E2SCRUB(8)                (August 2021)                E2SCRUB(8)

     NAME
          e2scrub_all - check all mounted ext[234] file systems 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 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 initi-
               ate 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.
