Hello

Hello,
Need help to repair and mount command be done to use a reiser4 volume ?
[located /dev/sdb]
# mount /dev/sdb /media/disk
- mount command [for sdb]
see http://www.spinics.net/lists/reiserfs-devel/msg04810.html
- These commands were run using opensuse 64 bit x86_64
- Steps run so far in this order:
# fsck.reiser4 --build-sb --force /dev/sdb
# fsck.reiser4 --build-fs --force /dev/sdb
# fsck.reiser4 --check /dev/sdb
Entire output see [1]
message sequence from commands:
-------------------------------
# fsck.reiser4 --build-sb --force /dev/sdb
2 fatal corruptions were detected in FileSystem. Run with --build-fs option to
fix them.
# fsck.reiser4 --build-fs --force /dev/sdb

my observations:
It seems to go loop around these commands.
No way to complete repair sequence to allow mount on volume.
So stuck in a loop of commands.
I know files and data are on disk but just cannot get to it.
Questions:
- Is this because of a bug in fsck: 'it jumps to wrong branch' ?
see http://www.spinics.net/lists/reiserfs-devel/msg04206.html
- How can repair be done to allow ?
Thanks
