[DRBD-user] Drbd 8.0.1 Inconsistent vs UpToDate

[Laurent CARON]

Hi

I did set up 2 servers with Drbd 8.0.1.

I've got 2 drbd devices (/dev/drbd0 and /dev/drbd1)

/dev/drbd0 is about 700	GB (XFS filesystem on top of it)
/dev/drbd1 is about 50 GB (XFS filesystem on top of it)

drbd1 is fine and UpToDate on both nodes

After waiting 6 hrs for drbd0 to sync, it is as follows on the nodes:

Node1:
version: 8.0.1 (api:86/proto:86)
SVN Revision: 2784 build by root at picsou, 2007-04-03 17:06:35

Node2:
version: 8.0.1 (api:86/proto:86)
SVN Revision: 2784 build by root at picsou, 2007-04-03 17:06:35

changed:45476
        act_log: used:0/257 hits:0 misses:0 starving:0 dirty:0 changed:0

/var/log/syslog of Node2 is filled with the following messages repeated
over and over:

Apr  5 11:36:41 node2 kernel: drbd0: Retrying drbd_rs_del_all() later.
refcnt=1

Messages appearing in node1's syslog:
Apr  5 11:33:56 node1 kernel: drbd0: ASSERT(
mdev->net_conf->wire_protocol == DRBD_PROT_A ) in
/usr/src/drbd-8.0.1/drbd/drbd_receiver.c:3193


If I try to reboot a node, drbd1 resyncs only the changed parts, however
drbd0 does a full resync.

Did I miss something ?

Thanks

Laurent
