NAME
       e2scrub_all - check all mounted ext[234] file systems for errors.

SYNOPSIS
       e2scrub_all [OPTION]

DESCRIPTION
       Searches the system for all LVM logical volumes containing an ext2,
       ext3, or ext4 file system, and checks them for problems.	 The checking
       is performed by invoking the e2scrub tool, which will look for
       corruptions.  Corrupt file systems will be tagged as having errors so
       that fsck will be invoked before the next mount.	 If no errors are
       encountered, fstrim will be called on the file system if it is mounted.
       See the e2scrub manual page for more information about how the checking
       is performed.

OPTIONS
       -n     Print what commands e2scrub_all would execute to initiate the
	      e2scrub operations.  (Note: these commands will not actually be
	      executed; however, since e2scrub_all needs to run some
	      additional, privileged commands to query the system to determine
	      which e2scrub commands would be executed, it still needs to be
	      run as root.)

       -r     Remove e2scrub snapshots but do not check anything.

       -A     Scrub all ext[234] file systems even if they are not mounted.

       -V     Print version information and exit.
