E2fsprogs version 1.47.2                          January 2025                                        E2SCRUB(8)

       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.

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

-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.
