41 .Nd journal file processing program
50 utility scans journal files for the purposes of debugging dumps, restoration,
51 undo, mirroring, and other journaling features.
52 .Bl -tag -width indent
54 dumps the contents of the journaling file in a human readable format.
56 will cause the journal be scanned backwards. Transactions will be dumped in
57 reverse order. However, note that due to parallelism the order will not be
58 the exact reverse of a forward scan, since large transactions are not dumped
59 until all stream segments have been collected for them.
67 This utility is currently under construction and not all features have been
68 implemented yet. In fact, most have not.
72 utility first appeared in DragonFly .
