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.

BUGS

       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:
       http://oss.software.ibm.com/jfs

       Please  send  as  much  pertinent information as possible, including any logredo error messages and the complete output of running fsck.jfs
       with the -v option on the JFS device.
