Hi all.
I'm trying to doing a simple cluster fo two nodes.
Every node is master for few services and in case of failure those
services will be transfered on the slave node.
On node1 will run a mail and db server, on the node2 will run dns and web.
For this i made four drbd block devices to serv each service.
I'm using heartbeat 2.1.3 with crm(v2) to manage the services and drbd
8.2.4.
Till yesterday no poblems...the servers were running smootly without
problems.
Then i tried to tune a bit drbd and here came the problems.
Everytime i changed something in drbd, i was cleaaning the crm config,
shut down the heartbeat, make sure all the services are stopped.
After every modify, i was trying running alone drbd and ahd always no
problems.
Then when i start heartbeat (that should manage the drbd devices), i see
many errors in crm_mon, so then i check drbd and i get this:
server1:
srv-clu-1:~# cat /proc/drbd
version: 8.2.4 (api:88/proto:86-88)

I cleaned again everything....resync all the drbd devices (i never
mounted a filesystem on them) restarted all the servers and started
again heartbeat. Everything seems ok, but when i go to check drbd i found:
1: cs:StandAlone st:Secondary/Unknown ds:UpToDate/DUnknown r---
ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0
resync: used:0/31 hits:0 misses:0 starving:0 dirty:0 changed:0
act_log: used:0/1801 hits:0 misses:0 starving:0 dirty:0 changed:0
It's not possible...i forced the sync on all to make them uptodate.
Why this error?
Anybody had a similar experience?
Thanks all.
Pier
