Ok, tested and now ok. I've also seen your mail on the DRBD mailling-list and the Lars' answer about the testing request (http://lists.linbit.com/pipermail/drbd-user/2009-May/012019.html). So the question is : do we want to provide both 8.2.7 (as drbd82 package) and 8.3.1 (as drbd83) ? It seems to me that drbd83 is 'just' an update to the 8.2.x branch (it could be named 8.2.10 in the Lars' answer)
Okay, did some tests on a heartbeat cluster.
At the moment I am running
[root@on3-temp1 ~]# head -1 /proc/drbd version: 8.3.1 (api:88/proto:86-89)
on one side of the cluster,
[root@on3-temp2 mnt]# head -1 /proc/drbd version: 8.0.16 (api:86/proto:86)
on the other side of the cluster withour problems (well, some advanced setup options are turned off, as 8.0 does not know about them.
Upgrading through the three versions was painless, failovers also work without problems between those two versions.
I haven't done any real stress tests, but the systems seem to work (I've bzip2d and bunzip2d for about an hour on each on node and then upgraded to the next drbd version, md5sums are still okay after that).
All tests on CentOS 5, I didn't have time for any tests on CentOS 4.
