.TH E2SCRUB 8 "@E2FSPROGS_MONTH@ @E2FSPROGS_YEAR@" "E2fsprogs version @E2FSPROGS_VERSION@"
|
|
.SH NAME
|
|
e2scrub_all - check all mounted ext[234] filesystems for errors.
|
|
.SH SYNOPSYS
|
|
.B
|
|
e2scrub_all [OPTION]
|
|
.SH 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
|
|
.B e2scrub
|
|
tool, which will look for corruptions.
|
|
Corrupt filesystems will be tagged as having errors so that fsck will be
|
|
invoked before the next mount.
|
|
If no errors are encountered,
|
|
.B fstrim
|
|
will be called on the filesystem if it is mounted.
|
|
See the
|
|
.B e2scrub
|
|
manual page for more information about how the checking is performed.
|
|
.SH OPTIONS
|
|
.TP
|
|
\fB-n\fR
|
|
Print what commands
|
|
.B e2scrub_all
|
|
would execute to initiate the e2scrub operations.
|
|
(Note: these commands will not actually be executed; however, since
|
|
.B e2scrub_all
|
|
needs to run some additional, privileged commands to query the
|
|
system to determine which
|
|
.B e2scrub
|
|
commands would be executed, it still needs to be run as root.)
|
|
.TP
|
|
\fB-r\fR
|
|
Remove e2scrub snapshots but do not check anything.
|
|
.TP
|
|
\fB-A\fR
|
|
Scrub all ext[234] filesystems even if they are not mounted.
|
|
.TP
|
|
\fB-V\fR
|
|
Print version information and exit.
