NAME
update-smart-drivedb - update smartmontools drive database
SYNOPSIS
update-smart-drivedb [OPTIONS] [DESTFILE]
DESCRIPTION
[This man page is generated for the Linux version of smartmontools. It does not contain info specific to other platforms.]
update-smart-drivedb updates /var/lib/smartmontools/drivedb/drivedb.h or DESTFILE from smartmontools SVN repository.
It tries to download first from the current branch and then from trunk. The tools used for downloading are either curl(1), wget(1),
lynx(1), or svn(1).
The old file is kept if the downloaded file is identical (ignoring the differences in Id string) otherwise it is moved to drivedb.h.old.
OPTIONS
-s SMARTCTL
Use the smartctl(8) executable at path SMARTCTL for drive database syntax check. The form '-s -' disables the syntax check. The
default is /usr/sbin/smartctl.
-t TOOL
Use TOOL for download. TOOL is one of: curl wget lynx svn. The default is the first one found in PATH.
-u LOCATION
Use URL of LOCATION for download. LOCATION is one of:
sf (Sourceforge code browser via HTTPS),
svn (SVN repository via HTTPS),
svni (SVN repository via HTTP),
trac (Trac code browser via HTTPS).
The default is svn.
--cacert FILE
Use CA certificates from FILE to verify the peer.
--capath DIR
Use CA certificate files from DIR to verify the peer.
--insecure
Don't abort download if certificate verification fails. This option is also required if a HTTP URL is selected with '-u' option.
--dryrun
Print download commands only.
-v Verbose output.
EXAMPLES
# update-smart-drivedb

NAME
smartd - SMART Disk Monitoring Daemon
SYNOPSIS
smartd [options]
FULL PATH
/usr/sbin/smartd
PACKAGE VERSION
smartmontools-6.2 2013-07-26 r3841
DESCRIPTION
[This man page is generated for the Linux version of smartmontools. It does not contain info specific to other platforms.]
smartd is a daemon that monitors the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into most ATA/SATA and
SCSI/SAS hard drives and solid-state drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive fail-
ures, and to carry out different types of drive self-tests. This version of smartd is compatible with ACS-2, ATA8-ACS, ATA/ATAPI-7 and
earlier standards (see REFERENCES below).
smartd will attempt to enable SMART monitoring on ATA devices (equivalent to smartctl -s on) and polls these and SCSI devices every 30 min-
utes (configurable), logging SMART errors and changes of SMART Attributes via the SYSLOG interface. The default location for these SYSLOG
notifications and warnings is system-dependent (typically /var/log/messages or /var/log/syslog). To change this default location, please
see the '-l' command-line option described below.
In addition to logging to a file, smartd can also be configured to send email warnings if problems are detected. Depending upon the type
of problem, you may want to run self-tests on the disk, back up the disk, replace the disk, or use a manufacturer's utility to force real-
location of bad or unreadable disk sectors. If disk problems are detected, please see the smartctl manual page and the smartmontools web
page/FAQ for further guidance.
If you send a USR1 signal to smartd it will immediately check the status of the disks, and then return to polling the disks every 30 min-
utes. See the '-i' option below for additional details.
smartd can be configured at start-up using the configuration file /etc/smartmontools/smartd.conf (Windows: EXEDIR/smartd.conf). If the
configuration file is subsequently modified, smartd can be told to re-read the configuration file by sending it a HUP signal, for example
with the command:
killall -HUP smartd.
On startup, if smartd finds a syntax error in the configuration file, it will print an error message and then exit. However if smartd is
already running, then is told with a HUP signal to re-read the configuration file, and then find a syntax error in this file, it will print
an error message and then continue, ignoring the contents of the (faulty) configuration file, as if the HUP signal had never been received.
When smartd is running in debug mode, the INT signal (normally generated from a shell with CONTROL-C) is treated in the same way as a HUP
signal: it makes smartd reload its configuration file. To exit smartd use CONTROL-
On startup, in the absence of the configuration file /etc/smartmontools/smartd.conf, the smartd daemon first scans for all devices that
support SMART. The scanning is done as follows:
LINUX: Examine all entries "/dev/hd[a-t]" for IDE/ATA devices, and "/dev/sd[a-z]", "/dev/sd[a-c][a-z]" for SCSI or SATA devices. Disks
behind RAID controllers are not included.
smartd then monitors for all possible SMART errors (corresponding to the '-a' Directive in the configuration file; see the smartd.conf(5)
man page).
OPTIONS
-A PREFIX, --attributelog=PREFIX
Writes smartd attribute information (normalized and raw attribute values) to files 'PREFIX''MODEL-SERIAL.ata.csv' or 'PREFIX''VEN-
DOR-MODEL-SERIAL.scsi.csv'. At each check cycle attributes are logged as a line of semicolon separated triplets of the form
"attribute-ID;attribute-norm-value;attribute-raw-value;". For SCSI devices error counters and temperature recorded in the form
"counter-name;counter-value;" Each line is led by a date string of the form "yyyy-mm-dd HH:MM:SS" (in UTC).
MODEL and SERIAL are build from drive identify information, invalid characters are replaced by underline.
If the PREFIX has the form '/path/dir/' (e.g. '/var/lib/smartd/'), then files 'MODEL-SERIAL.ata.csv' are created in directory
'/path/dir'. If the PREFIX has the form '/path/name' (e.g. '/var/lib/misc/attrlog-'), then files 'nameMODEL-SERIAL.ata.csv' are
created in directory '/path/'. The path must be absolute, except if debug mode is enabled.
-B [+]FILE, --drivedb=[+]FILE
[ATA only] Read the drive database from FILE. The new database replaces the built in database by default. If '+' is specified,
then the new entries prepend the built in entries. Please see the smartctl(8) man page for further details.
-c FILE, --configfile=FILE
Read smartd configuration Directives from FILE, instead of from the default location /etc/smartmontools/smartd.conf (Windows:
EXEDIR/smartd.conf). If FILE does not exist, then smartd will print an error message and exit with nonzero status. Thus, '-c
/etc/smartmontools/smartd.conf' can be used to verify the existence of the default configuration file.
By using '-' for FILE, the configuration is read from standard input. This is useful for commands like:
echo /dev/hdb -m user@home -M test | smartd -c - -q onecheck
to perform quick and simple checks without a configuration file.
-C, --capabilities
Use capabilities(7).
Warning: Mail notification does not work when used.
-d, --debug
Runs smartd in "debug" mode. In this mode, it displays status information to STDOUT rather than logging it to SYSLOG and does not
fork(2) into the background and detach from the controlling terminal. In this mode, smartd also prints more verbose information
about what it is doing than when operating in "daemon" mode. In this mode, the INT signal (normally generated from a terminal with
CONTROL-C) makes smartd reload its configuration file. Please use CONTROL- to exit
-D, --showdirectives
Prints a list (to STDOUT) of all the possible Directives which may appear in the configuration file /etc/smartmontools/smartd.conf,
and then exits. These Directives are also described later in this man page. They may appear in the configuration file following the
device name.
-h, --help, --usage
Prints usage message to STDOUT and exits.
-i N, --interval=N
Sets the interval between disk checks to N seconds, where N is a decimal integer. The minimum allowed value is ten and the maximum
is the largest positive integer that can be represented on your system (often 2^31-1). The default is 1800 seconds.
Note that the superuser can make smartd check the status of the disks at any time by sending it the SIGUSR1 signal, for example with
the command:
kill -SIGUSR1 <pid>
where <pid> is the process id number of smartd. One may also use:
killall -USR1 smartd
for the same purpose.
-l FACILITY, --logfacility=FACILITY
Uses syslog facility FACILITY to log the messages from smartd. Here FACILITY is one of local0, local1, ..., local7, or daemon
[default]. If this command-line option is not used, then by default messages from smartd are logged to the facility daemon.
If you would like to have smartd messages logged somewhere other than the default location, this can typically be accomplished with
(for example) the following steps:
[1] Modify the script that starts smartd to include the smartd command-line argument '-l local3'. This tells smartd to log its mes-
sages to facility local3.
[2] Modify the syslogd configuration file (typically /etc/syslog.conf) by adding a line of the form:
local3.* /var/log/smartd.log
This tells syslogd to log all the messages from facility local3 to the designated file: /var/log/smartd.log.
[3] Tell syslogd to re-read its configuration file, typically by sending the syslogd process a SIGHUP hang-up signal.
[4] Start (or restart) the smartd daemon.
For more detailed information, please refer to the man pages for syslog.conf, syslogd, and syslog. You may also want to modify the
log rotation configuration files; see the man pages for logrotate and examine your system's /etc/logrotate.conf file.
-n, --no-fork
Do not fork into background; this is useful when executed from modern init methods like initng, minit or supervise.
-p NAME, --pidfile=NAME
Writes pidfile NAME containing the smartd Process ID number (PID). To avoid symlink attacks make sure the directory to which pid-
file is written is only writable for root. Without this option, or if the --debug option is given, no PID file is written on
startup. If smartd is killed with a maskable signal then the pidfile is removed.
-q WHEN, --quit=WHEN
Specifies when, if ever, smartd should exit. The valid arguments are to this option are:
nodev - Exit if there are no devices to monitor, or if any errors are found at startup in the configuration file. This is the
default.
errors - Exit if there are no devices to monitor, or if any errors are found in the configuration file /etc/smartmon-
tools/smartd.conf at startup or whenever it is reloaded.
nodevstartup - Exit if there are no devices to monitor at startup. But continue to run if no devices are found whenever the config-
uration file is reloaded.
never - Only exit if a fatal error occurs (no remaining system memory, invalid command line arguments). In this mode, even if there
are no devices to monitor, or if the configuration file /etc/smartmontools/smartd.conf has errors, smartd will continue to run,
waiting to load a configuration file listing valid devices.
onecheck - Start smartd in debug mode, then register devices, then check device's SMART status once, and then exit with zero exit
status if all of these steps worked correctly.
This last option is intended for 'distribution-writers' who want to create automated scripts to determine whether or not to automat-
ically start up smartd after installing smartmontools. After starting smartd with this command-line option, the distribution's
install scripts should wait a reasonable length of time (say ten seconds). If smartd has not exited with zero status by that time,
the script should send smartd a SIGTERM or SIGKILL and assume that smartd will not operate correctly on the host. Conversely, if
smartd exits with zero status, then it is safe to run smartd in normal daemon mode. If smartd is unable to monitor any devices or
encounters other problems then it will return with non-zero exit status.
showtests - Start smartd in debug mode, then register devices, then write a list of future scheduled self tests to stdout, and then
exit with zero exit status if all of these steps worked correctly. Device's SMART status is not checked.
This option is intended to test whether the '-s REGEX' directives in smartd.conf will have the desired effect. The output lists the
next test schedules, limited to 5 tests per type and device. This is followed by a summary of all tests of each device within the
next 90 days.
-r TYPE, --report=TYPE
Intended primarily to help smartmontools developers understand the behavior of smartmontools on non-conforming or poorly-conforming
hardware. This option reports details of smartd transactions with the device. The option can be used multiple times. When used
just once, it shows a record of the ioctl() transactions with the device. When used more than once, the detail of these ioctl()
transactions are reported in greater detail. The valid arguments to this option are:
ioctl - report all ioctl() transactions.
ataioctl - report only ioctl() transactions with ATA devices.
scsiioctl - report only ioctl() transactions with SCSI devices.
Any argument may include a positive integer to specify the level of detail that should be reported. The argument should be followed
by a comma then the integer with no spaces. For example, ataioctl,2 The default level is 1, so '-r ataioctl,1' and '-r ataioctl'
are equivalent.
-s PREFIX, --savestates=PREFIX
Reads/writes smartd state information from/to files 'PREFIX''MODEL-SERIAL.ata.state' or 'PREFIX''VENDOR-MODEL-SERIAL.scsi.state'.
This preserves SMART attributes, drive min and max temperatures (-W directive), info about last sent warning email (-m directive),
and the time of next check of the self-test REGEXP (-s directive) across boot cycles.
MODEL and SERIAL are build from drive identify information, invalid characters are replaced by underline.
If the PREFIX has the form '/path/dir/' (e.g. '/var/lib/smartd/'), then files 'MODEL-SERIAL.ata.state' are created in directory
'/path/dir'. If the PREFIX has the form '/path/name' (e.g. '/var/lib/misc/smartd-'), then files 'nameMODEL-SERIAL.ata.state' are
created in directory '/path/'. The path must be absolute, except if debug mode is enabled.
The state information files are read on smartd startup. The files are always (re)written after reading the configuration file,
before rereading the configuration file (SIGHUP), before smartd shutdown, and after a check forced by SIGUSR1. After a normal check
cycle, a file is only rewritten if an important change (which usually results in a SYSLOG output) occurred.
-w PATH, --warnexec=PATH
[NEW EXPERIMENTAL SMARTD FEATURE] Run the executable PATH instead of the default script when smartd needs to send warning messages.
PATH must point to an executable binary file or script. The default script is /etc/smartmontools/smartd_warning.sh.
-V, --version, --license, --copyright
Prints version, copyright, license, home page and SVN revision information for your copy of smartd to STDOUT and then exits. Please
include this information if you are reporting bugs or problems.
EXAMPLES
smartd
Runs the daemon in forked mode. This is the normal way to run smartd. Entries are logged to SYSLOG.
smartd -d -i 30
Run in foreground (debug) mode, checking the disk status every 30 seconds.
smartd -q onecheck
Registers devices, and checks the status of the devices exactly once. The exit status (the bash $? variable) will be zero if all went
well, and nonzero if no devices were detected or some other problem was encountered.
Note that smartmontools provides a start-up script in /smartd which is responsible for starting and stopping the daemon via the normal init
interface. Using this script, you can start smartd by giving the command:
/smartd start
and stop it by using the command:
/smartd stop
CONFIGURATION
The syntax of the smartd.conf(5) file is discussed separately.
NOTES
smartd will make log entries at loglevel LOG_INFO if the Normalized SMART Attribute values have changed, as reported using the '-t', '-p',
or '-u' Directives. For example:
'Device: /dev/hda, SMART Attribute: 194 Temperature_Celsius changed from 94 to 93'
Note that in this message, the value given is the 'Normalized' not the 'Raw' Attribute value (the disk temperature in this case is about 22
Celsius). The '-R' and '-r' Directives modify this behavior, so that the information is printed with the Raw values as well, for example:
'Device: /dev/hda, SMART Attribute: 194 Temperature_Celsius changed from 94 [Raw 22] to 93 [Raw 23]'
Here the Raw values are the actual disk temperatures in Celsius. The way in which the Raw values are printed, and the names under which
the Attributes are reported, is governed by the various '-v Num,Description' Directives described previously.
Please see the smartctl manual page for further explanation of the differences between Normalized and Raw Attribute values.
smartd will make log entries at loglevel LOG_CRIT if a SMART Attribute has failed, for example:
'Device: /dev/hdc, Failed SMART Attribute: 5 Reallocated_Sector_Ct'
This loglevel is used for reporting enabled by the '-H', -f', '-l selftest', and '-l error' Directives. Entries reporting failure of SMART
Prefailure Attributes should not be ignored: they mean that the disk is failing. Use the smartctl utility to investigate.
LOG TIMESTAMP TIMEZONE
When smartd makes log entries, these are time-stamped. The time stamps are in the computer's local time zone, which is generally set using
either the environment variable 'TZ' or using a time-zone file such as /etc/localtime. You may wish to change the timezone while smartd is
running (for example, if you carry a laptop to a new time-zone and don't reboot it). Due to a bug in the tzset(3) function of many unix
standard C libraries, the time-zone stamps of smartd might not change. For some systems, smartd will work around this problem if the time-
zone is set using /etc/localtime. The work-around fails if the time-zone is set using the 'TZ' variable (or a file that it points to).
RETURN VALUES
The return value (exit status) of smartd can have the following values:
0: Daemon startup successful, or smartd was killed by a SIGTERM (or in debug mode, a SIGQUIT).
1: Commandline did not parse.
2: There was a syntax error in the config file.
3: Forking the daemon failed.
4: Couldn't create PID file.
5: Config file does not exist (only returned in conjunction with the '-c' option).
6: Config file exists, but cannot be read.
8: smartd ran out of memory during startup.
9: A compile time constant of smartd was too small. This can be caused by an excessive number of disks, or by lines in /etc/smartmon-
tools/smartd.conf that are too long. Please report this problem to smartmontools-support@lists.sourceforge.net.
10: An inconsistency was found in smartd's internal data structures. This should never happen. It must be due to either a coding or
compiler bug. Please report such failures to smartmontools-support@lists.sourceforge.net.
16: A device explicitly listed in /etc/smartmontools/smartd.conf can't be monitored.
17: smartd didn't find any devices to monitor.
254: When in daemon mode, smartd received a SIGINT or SIGQUIT. (Note that in debug mode, SIGINT has the same effect as SIGHUP, and makes
smartd reload its configuration file. SIGQUIT has the same effect as SIGTERM and causes smartd to exit with zero exit status.
132 and above
smartd was killed by a signal that is not explicitly listed above. The exit status is then 128 plus the signal number. For example
if smartd is killed by SIGKILL (signal 9) then the exit status is 137.

An introductory article about smartmontools is Monitoring Hard Disks with SMART, by Bruce Allen, Linux Journal, January 2004, pages 74-77.
This is http://www.linuxjournal.com/article/6983 online.
If you would like to understand better how SMART works, and what it does, a good place to start is with Sections 4.8 and 6.54 of the first
volume of the 'AT Attachment with Packet Interface-7' (ATA/ATAPI-7) specification Revision 4b. This documents the SMART functionality
which the smartmontools utilities provide access to.
The functioning of SMART was originally defined by the SFF-8035i revision 2 and the SFF-8055i revision 1.4 specifications. These are pub-
lications of the Small Form Factors (SFF) Committee.
