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


       e2scrub_all [OPTION]


       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.


       -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.
