.SH NAME
|
|
e2undo \- Replay an undo log for an ext2/ext3/ext4 filesystem
|
|
.SH SYNOPSIS
|
|
.B e2undo
|
|
[
|
|
.B \-f
|
|
]
|
|
.I undo_log device
|
|
.SH DESCRIPTION
|
|
.B e2undo
|
|
will replay the undo log
|
|
.I undo_log
|
|
for an ext2/ext3/ext4 filesystem found on
|
|
.IR device .
|
|
This can be
|
|
used to undo a failed operation by an e2fsprogs program.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-f
|
|
Normally,
|
|
.B e2undo
|
|
will check the filesystem UUID and last modified time to make sure the
|
|
undo log matches with the filesystem on the device. If they do not
|
|
match,
|
|
.B e2undo
|
|
will refuse to apply the undo log as a safety mechanism. The
|
|
.B \-f
|
|
option disables this safety mechanism.
