Hi Simon,

Latest is much better on this end :). After the reboot, I get :

# clform -join
INFO  24/01/2005 19:36:35 Validated checksum for cluster configuration
INFO  24/01/2005 19:36:35 Checking cluster status...

INFO  24/01/2005 19:36:46 Node p-5.ednet.ns.ca successfully joined cluster.

After which the cluser shows as active.

But... then it appears that I must load the drbd module myself or the 
syncing doesn't startup. Maybe I do not wait long enough?

Then the sync begins, but during this time I get a small perl error when 
I issue clstat :

# clstat -application mysql
Cluster: cluster1 - UP

Which goes away once the sync is complete.

Also... :(, the sync takes as long as if I was syncing from nothing. I 
thought during my tests of drbd alone that if on in the drbd pair was 
off line for just a while then the sync happened quite fast? It appears 
to be syncing as if a new Secondary is being brought into the cluster? 
Of course maybe I'm just expecting it to be too fast ;).

Thanks for your quick responses. Now to do more tests :).

take care,
JES
