logredo(8) JFS utility - replay journal log logredo(8)
NAME
logredo - "replay" a JFS formatted device's journal log
SYNOPSIS
logredo device
DESCRIPTION
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.
WARNING
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.

with the -v option on the JFS device.
