hi,
debian lenny,
pacemaker 1.0.9-74392a28b7f31d7ddc86689598bd23114f58978b,
drbd 8.3.10 5c0b0469666682443d4785d90a2c603378f9017b,
ocf ra 1.3 shipped with (self-compiled drbd debian package)
kernel 2.6.27.57+ipax
every couple of hours, i encounter a digest mismatch:
> Digest mismatch, buffer modified by upper layers during write: 0s +4096
leading ro a disconnect and reconnect (by pacemaker+drbd) and
a split view after the resync, e.g.:
node1:
> version: 8.3.10 (api:88/proto:86-96)
> GIT-hash: 5c0b0469666682443d4785d90a2c603378f9017b build by [email protected],

node2:

> oos:0
as you can see, node1 reports ds: "UpToDate/DUnknown" whereas
node2 reports "UpToDate/UpToDate"
config and dmesg logs attached. for your information:
Feb 16 06:25:03: devices get out of sync.
Feb 16 13:34:32: i manually disconnect and reconnect from node01 to
start resync.
looks like a bug to me, doesn't it?
i have a couple of 2 node clusters running this setup.
for a test, i will upgrade one of them to a more recent kernel from
squeeze and thus will downgrade drbd to squezze's drbd 8.3.7.
cheers,
raoul
