Dear All, The two nodes forming my cluster do not see each others file-system changes. Just as if each node would be mounting a cluster unaware file-system! My configuration is identical on both the nodes and looks like: ,----[ # cat /etc/ocfs2/cluster.conf ] | cluster: | node_count = 2 | name = ocfs2 | | node: | ip_port = 7777 | ip_address = 192.168.4.130 | number = 1 | name = gbgen01 | cluster = ocfs2 | | node: | ip_port = 7777 | ip_address = 192.168.4.161 | number = 2 | name = gbgen02 | cluster = ocfs2 `---- On the first node (gbgen01) the device /dev/sdd2 is formatted with: $> mkfs.ocfs2 -L share -N 2 /dev/sdd2 I exported the device via 'aoe' driver and could mount the device on both nodes with the same command: $> mount -t ocfs2 -L share /mnt/ocfs2 But fs changes became nor visible on the other node, until I unmount and mount the share again. Example: ,----[ gbgen01 ocfs2 # mount | grep ocfs2 ] | none on /dlm type ocfs2_dlmfs (rw) | /dev/sdd2 on /mnt/ocfs2 type ocfs2 (rw,_netdev,heartbeat=local) `---- gbgen01 ocfs2 # cd /mnt/ocfs2 gbgen01 ocfs2 # touch a gbgen01 ocfs2 # ls -l total 0 ,----[ gbgen02 ocfs2 # mount | grep ocfs2 ] | none on /dlm type ocfs2_dlmfs (rw) | /dev/etherd/e0.0 on /mnt/ocfs2 type ocfs2 (rw,_netdev,heartbeat=local) `---- gbgen02 ocfs2 # cd /mnt/ocfs2 gbgen02 ocfs2 # touch b gbgen02 ocfs2 # ls -l total 4 -rw-r--r-- 1 root root 0 Jan 11 15:09 b drwxr-xr-x 2 root root 4096 Jan 11 14:08 lost+found On both servers, 'o2cb status' does not report anything indicating the problem (everything active and loaded ok). I have tried the following kernel versions, but could see the same result no matter which I used: vmlinuz-2.6.17-hardened-r1 vmlinuz-2.6.18-gentoo-r6 vmlinuz-2.6.19.1 Is there something very basical I missed during my configuration? Thanks for your help in advance! Best Regards, Gerrit
