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

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 sys‐
       tem, 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 informa‐
       tion 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.
