Are you sure? [y/n] y current lock table name = "arev_clust:LogVol01" new lock table name = "arev_clust:LogVol01" Done mkfs.gfs2 -p lock_dlm -t arev_clust:LogVol01 -j 1 /dev/VolGroup01/LogVol01 This will destroy any data on /dev/VolGroup01/LogVol01. It appears to contain a gfs2 filesystem. Are you sure you want to proceed? [y/n] y Device: /dev/VolGroup01/LogVol01 Blocksize: 4096 Device Size 240.00 GB (62913536 blocks) Filesystem Size: 240.00 GB (62913535 blocks) Journals: 1 Resource Groups: 960 Locking Protocol: "lock_dlm" Lock Table: "arev_clust:LogVol01" BUT when i want to mount th e gfs FS i got: # mount -t gfs2 /dev/VolGroup01/LogVol01 /appli/prod /sbin/mount.gfs2: can't connect to gfs_controld: Connection refused And the starting of the service gives the same error: cman not started: Multicast and node address families differ. /usr/sbin/cman_tool: aisexec daemon didn't start [FAILED] When i creating the cluster via Conga this is below the error i got: The following errors occurred: * Unable to add the key for node gs21spli004.occ.lan to the trusted keys list. * Unable to connect to host2.occ.lan: Unable to establish an SSL connection to host2.occ.lan:11111: ClientSocket(hostname, port, timeout): connect() failed * host1.occ.lan reports it is a member of cluster "arev_clust" Of course the port 1111 is opened: tcp 0 0 0.0.0.0:11111 0.0.0.0:* LISTEN 0 573641 9435/ricci SO what can you advise me i'm really lost. greetings <DIV> ntoughe@hotmail.com</DIV> <hr />See all the ways you can stay connected <a href='http://www.microsoft.com/windows/windowslive/default.aspx' target='_new'>to friends and family</a></body> </html>
