   2 .SH NAME
   3 e2scrub_all - check all mounted ext[234] filesystems for errors.
   4 .SH SYNOPSYS
   5 .B
   6 e2scrub_all [OPTION]
   7 .SH DESCRIPTION
   8 Searches the system for all LVM logical volumes containing an ext2, ext3, or
   9 ext4 file system, and checks them for problems.
  10 The checking is performed by invoking the
  11 .B e2scrub
  12 tool, which will look for corruptions.
  13 Corrupt filesystems will be tagged as having errors so that fsck will be
  14 invoked before the next mount.
  15 If no errors are encountered,
  16 .B fstrim
  17 will be called on the filesystem if it is mounted.
  18 See the
  19 .B e2scrub
  20 manual page for more information about how the checking is performed.
  21 .SH OPTIONS
  22 .TP
  23 \fB-n\fR
  24 Print what commands
  25 .B e2scrub_all
  26 would execute to initiate the e2scrub operations.
  27 (Note: these commands will not actually be executed; however, since
  28 .B e2scrub_all
  29 needs to run some additional, privileged commands to query the
  30 system to determine which
  31 .B e2scrub
  32 commands would be executed, it still needs to be run as root.)
  33 .TP
  34 \fB-r\fR
  35 Remove e2scrub snapshots but do not check anything.
  36 .TP
  37 \fB-A\fR
  38 Scrub all ext[234] filesystems even if they are not mounted.
  39 .TP
  40 \fB-V\fR
  41 Print version information and exit.
