NAME

6       e2scrub_all - check all mounted ext[234] file systems for errors.
7

SYNOPSIS

9       e2scrub_all [OPTION]
10

DESCRIPTION

12       Searches  the  system  for  all LVM logical volumes containing an ext2,
13       ext3, or ext4 file system, and checks them for problems.  The  checking
14       is  performed by invoking the e2scrub tool, which will look for corrup‐
15       tions.  Corrupt file systems will be tagged as having  errors  so  that
16       fsck  will  be invoked before the next mount.  If no errors are encoun‐
17       tered, fstrim will be called on the file system if it is mounted.   See
18       the  e2scrub manual page for more information about how the checking is
19       performed.

OPTIONS

22       -n     Print what commands e2scrub_all would execute  to  initiate  the
23              e2scrub  operations.  (Note: these commands will not actually be
24              executed; however, since e2scrub_all needs  to  run  some  addi‐
25              tional,  privileged  commands  to  query the system to determine
26              which e2scrub commands would be executed, it still needs  to  be
27              run as root.)
28
29       -r     Remove e2scrub snapshots but do not check anything.
30
31       -A     Scrub all ext[234] file systems even if they are not mounted.
32
33       -V     Print version information and exit.
