If you are able to unmount the file system cleanly, you won't lose anything. You can reformat the journal with mkfs.jfs -J journal_dev /dev/xxx. Then you will need to run jfs_tune -J device=/dev/xxx /dev/fsdev to associate the journal with the file system. If the journal is lost after a system crash or power failure before fsck was able to replay the journal, you may lose some data. fsck will fail to replay the journal, and will attempt to repair anything it finds to be inconsistent. fsck should attempt to reformat the journal if it can still open the journal device. > Also what happens when the logfile hits max size? The journal is logically circular and should never run out of space. -- David Kleikamp IBM Linux Technology Center _______________________________________________ Jfs-discussion mailing list [EMAIL PROTECTED] http://www-124.ibm.com/developerworks/oss/mailman/listinfo/jfs-discussion
