| 6 | .SH NAME |
| 7 | e2undo \- Replay an undo log for an ext2/ext3/ext4 filesystem |
| 8 | .SH SYNOPSIS |
| 9 | .B e2undo |
| 10 | [ |
| 11 | .B \-f |
| 12 | ] |
| 13 | .I undo_log device |
| 14 | .SH DESCRIPTION |
| 15 | .B e2undo |
| 16 | will replay the undo log |
| 17 | .I undo_log |
| 18 | for an ext2/ext3/ext4 filesystem found on |
| 19 | .IR device . |
| 20 | This can be |
| 21 | used to undo a failed operation by an e2fsprogs program. |
| 22 | .SH OPTIONS |
| 23 | .TP |
| 24 | .B \-f |
| 25 | Normally, |
| 26 | .B e2undo |
| 27 | will check the filesystem UUID and last modified time to make sure the |
| 28 | undo log matches with the filesystem on the device. If they do not |
| 29 | match, |
| 30 | .B e2undo |
| 31 | will refuse to apply the undo log as a safety mechanism. The |
| 32 | .B \-f |
| 33 | option disables this safety mechanism. |
