E2SCRUB(8)                  System Manager's Manual                 E2SCRUB(8)

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

SYNOPSYS
       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 corrup-
       tions.  Corrupt filesystems will be tagged as  having  errors  so  that
       fsck  will  be invoked before the next mount.  If no errors are encoun-
       tered, fstrim will be called on the filesystem 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  addi-
              tional,  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] filesystems even if they are not mounted.

       -V     Print version information and exit.
