>Description:
>How-To-Repeat:

>Fix:
By the way is there any effort to support ext3? Ext2 partitions corrupt on crashes, xfs seems to be unstable. Besides this ext3 would pose the only way to share a common home partition between Linux, FreeBSD and Windows.

 ERROR: The filesystem has valuable metadata changes in a log which needs to
 be replayed.  Mount the filesystem to replay the log, and unmount it before
 re-running xfs_check.  If you are unable to mount the filesystem, then use
 the xfs_repair -L option to destroy the log and attempt a repair.
 Note that destroying the log may cause corruption -- please attempt a mount
 of the filesystem before doing this.
