|E2UNDO(8)||System Manager's Manual||E2UNDO(8)|
- Normally, 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, e2undo will refuse to apply the undo log as a safety mechanism. The -f option disables this safety mechanism.
