thin_check - repair thin provisioning metadata on device or file
SYNOPSIS
thin_check [options] {device|file}
DESCRIPTION
thin_check checks thin provisioning metadata created by the device-mapper thin provisioning target on a device or file.
OPTIONS -q, --quiet
Suppress output messages, return only exit code.
-h, --help
Print help and exit.
-V, --version
Output version information and exit.
--super-block-only
Only check the superblock is present.
--skip-mappings
Skip checking of the block mappings which make up the bulk of the metadata.
--ignore-non-fatal-errors
thin_check will only return a non-zero exit code if it finds a fatal error. An example of a on fatal error is an incorrect data
block reference count causing a block to be considered allocated when it in fact isn't. Ignoring errors for a long time is not
advised, you really should be using thin_repair to fix them.
EXAMPLE
Analyses and repairs thin provisioning metadata on logical volume /dev/vg/metadata:
thin_check /dev/vg/metadata
The device may not be actively used by the target when running.
DIAGNOSTICS
thin_check returns an exit code of 0 for success or 1 for error.

Just was wondering how many CD's are required to install RedHat 8. I thought I remember reading that only the first 3 are needed. The last 2 are just source code.
Then talking with from friends, they said all 5 are needed.
What's the correct number?
Thanks!

How can I find out with a C program, on which RedHat version the program is being ran ? I do know through compilation variables that I'm on RedHat but so far cannot find out which one.
