Hmm...trying to reproduce this on 2.4.6...and after applying the lvm 0.9.1
beta8 patch, the linux-2.4.4-VFS-lock patch and the above patch (in that
order), I still get this when trying to create and mount a snapshot:
reiserfs: checking transaction log (device 3a:00) ...
Using r5 hash to sort names
ReiserFS version 3.6.25
reiserfs: checking transaction log (device 3a:01) ...
clm-2076: device is readonly, unable to replay log
Replay Failure, unable to mount
reiserfs_read_super: unable to initialize journal space
Is there some other patch or magic I need to do to get ReiserFS snapshots
working? I thought the VFS-lock patch was supposed to fix that...
Regards,
