Hi there, We are trying to setup a two-nodes cluster using clumanager. After add the two member to the cluster and create the rawdevices, all the member are inactived, the clustat's output is: Cluster Status - mail-cluster 15:04:38 Incarnation #0 (This member is not part of the cluster quorum) Member Status ------------------ ---------- 192.168.0.151 Inactive 192.168.0.152 Inactive <-- You are here No Quorum - Service States Unknown ------------------------------------------------------------------- Both member have access to the shared raw partition in the storage, here is the clurawtest's output: Starting exercises... 1 iterations run in 0 days, 00:00:05 Write Exercise Passes: 1 * 269 successful writes Read Exercise Passes: 3 * 621 successful reads * 617 successful data integrity checks Overall result: Pass ------------------------------------------------------------------- and these are the entries in message: Dec 10 15:06:33 atmail-1 clumanager: cluquorumd startup succeeded Dec 10 15:06:33 atmail-1 cluquorumd[6347]: <warning> STONITH: No drivers configured for host '192.168.0.151'!

Dec 10 15:06:33 atmail-1 cluquorumd[6347]: <warning> STONITH: Data integrity may be compromised! At this time we don't have any service created just the two cluster's member. Any idea? Regards, fausto
