+.SH NAME
+e2scrub_all - check all mounted ext[234] file systems for errors.
+.SH SYNOPSIS
+.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 file systems 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 file system 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] file systems even if they are not mounted.
+.TP
+\fB-V\fR
+Print version information and exit.
