A quick question:
Is there a way to replay the journal log for an XFS
filesystem after an unclean shutdown without actually
mounting the filesystem ?
No, replay only happens in kenelspace. It's possible to do it in
userspace, and it's been talked about, but never implemented.
I see that "mount" will replay the journal but then
it'll mount the filesystem too after the replaying is
I looked at various debug/admin tools in xfsprogs but
didn't see any such option although I could have very
well missed something.
