ReiserFS - deadlock

Hi,

DRBD + ReiserFS is doing some crazy stuff.
Just wondering if there are patches out there that fix anything :-)
I just copied (successfully) 3.5Gig of data from a RAID1 ReiserFS drbd device
on node 1 to a ReiserFS drbd device (no RAID) on node 2.

All went well - no error messages and very fast during copy (mode B was used)
But - when I went to make the primary a secondary, a deadlock occured
(ReiserFS complained about finding a block which belongs at a different
address, or something ... I will try to recreate this ... too bad my root
partition, which is SCSI and was not used for DRBD at all, seems to have
commited suicide :-(

I'm using kernel 2.2.17 with the ReiserFS 3.5.27 patch and Marcelo's DRBD
deadlock patch. Also, mingo's RAID patches where applied. DRBD is latest CVS
version as of this morning.

Any help appreciated :-)

Best Regards,

As Marcelo posted previously on the list you may want to use the pre 18
See the list archive for more info

Is reiser not needing to write the block in order to keep the journaling
information sync with what is on the drive ?

You should not use RAID1 on 2.2x with any journalling filesystem.
