RAIDFILE-CONFIG(8)						    Box Backup							RAIDFILE-CONFIG(8)

NAME

       raidfile-config - Configure Box Backup's RAID files

SYNOPSIS

       raidfile-config config-dir blocksize dir1 [dir2 [dir3]]

DESCRIPTION

       raidfile-config creates a raidfile.conf file for Box Backup. This file holds information about the directories used to store backups in.
       Box Backup supports userland RAID, in a restricted RAID5 configuration, where 3 and only 3 'drives' are supported. You can read more about
       RAID5 (and other RAID-levels) here[1].

   Parameters
       The parameters are as follows:

       config-dir
	   The directory path where configuration files are located. Usually this is /etc/box.	raidfile.conf will be written in this directory.

       blocksize
	   The block size used for file storage in the system, in bytes. Using a multiple of the file system block size is a good strategy.
	   Depending on the size of the files you will be backing up, this multiple varies. Of course it also depends on the native block size of
	   your file system.

       dir1
	   The first directory in the built-in RAID array.

       dir2
	   The second directory in the built-in RAID array. If you are not using the built-in RAID functionality, this field should be ignored.
	   You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software RAID (like md on
	   Linux).

       dir3
	   The third directory in the built-in RAID array. The same notes that apply to dir2 also apply to dir3.

       Note that there are currently no way to add multiple disk sets to the raidfile.conf file using command line tools, etc. See
       raidfile.conf(5) for details on adding more disks.

BUGS

       If you find a bug in Box Backup, and you want to let us know about it, join the mailing list[2], and send a description of the problem
       there.

       To report a bug, give us at least the following information:

       o   The version of Box Backup you are running

       o   The platform you are running on (hardware and OS), for both client and server.

       o   If possible attach your config files (bbstored.conf, bbackupd.conf) to the bug report.

       o   Also attach any log file output that helps shed light on the problem you are seeing.

       o   And last but certainly not least, a description of what you are seeing, in as much detail as possible.

NAME

       raidstart, raidstop, - command set to manage md devices.

SYNOPSIS

       raidstart [options] <raiddevice>*

       raidstop [options] <raiddevice>*

DESCRIPTION

       RAID  devices  are  virtual  devices  created  from two or more real block devices. This allows multiple disks to be combined into a single
       filesystem, possibly with automated backup and recovery. Linux RAID devices are implemented through the md device driver.

       If you're using the /proc filesystem, /proc/mdstat gives you informations about md devices status.

       Currently, Linux supports linear md devices, RAID0 (striping), RAID1 (mirrroring), and RAID4 and RAID5. For information on the various lev-
       els of RAID, check out:

	    http://ostenfeld.dk/~jakob/Software-RAID.HOWTO/

       for new releases of the RAID driver check out:

	    ftp://ftp.fi.kernel.org/pub/linux/daemons/raid/alpha

       Avaible commands are :

       mkraid : configures (creates) md (RAID) devices in the kernel, banding multiple devices into one.

       raidstart : activates (starts) an existing 'persistent' md device

       raid0run : activates old nonpersistent RAID0/LINEAR md devices

       raidstop : turns off an md device, and unconfigures (stops) it

       By default, a systems RAID configuration is kept in /etc/raidtab, which can configure multiple RAID devices.

       All  of	these  tools  work similiarly. If -a (or --all) is specified, the specified operation is performed on all of the RAID devices men-
       tioned in the configuration file. Otherwise, one or more RAID devices must be specified on the command line. For example:

       raid0run -a

       Starts all of the 'old' RAID0 RAID devices specified in /etc/raidtab. If only /dev/md1 should be started, the following command	should	be
       used instead:

       raidstart /dev/md1

OPTIONS

       -a, --all
	      Apply the command to all of the configurations specified in the config file.

       -c, --configfile filename
	      Use filename as the configuration file (/etc/raidtab is used by default).

       -h, --help
	      Displays a short usage message, then exits.

       -V, --version
	      Displays a short version message, then exits.

NOTES

       The  raidtools  are  derived from the md-tools and raidtools packages, which were originally written by Marc Zyngier, Miguel de Icaza, Gadi
       Oxman, Bradley Ward Allen, and Ingo Molnar.

BUGS

       no known bugs.
