logredo(8) JFS utility - replay journal log logredo(8)
logredo - "replay" a JFS formatted device's journal log
logredo applies all committed transactions recorded in the JFS journal log since the most
recent synch point. Its goal is to put the JFS file system in the state it would have
been in if all transactions had been applied, in order, by the JFS file system itself.
device is the special file name corresponding to the actual device on which the journal
log will be replayed (e.g. /dev/hdb1 ).
logredo must be run as root.
logredo is called from within fsck.jfs, and is not recommended to be run as a stand-alone
utility unless completely necessary, and only by advanced users with a clear understanding
of journaling in a file system.
If you find a bug in JFS or logredo, please report it via the bug tracking system ("Report
Bugs" section) of the JFS project web site:
Please send as much pertinent information as possible, including any logredo error mes-
sages and the complete output of running fsck.jfs with the -v option on the JFS device.
