I am not sure which group to post this to. If this isn’t the right one, please let me know. I have set up a DRBD cluster for replicating a drbd volume across two servers. Each server has its own IP address (10.89.99.31 and 10.89.99.32). I also have a collocated IP address (10.89.99.30) used for mounting the volume on other computers. I am using cman and pacemaker. I can mount the volume with no issues using 10.89.99.30. When I unplug the network cable from my second storage server, the computer will lose connectivity to the NFS share, even though the IP address shows it is shared. I can still ping 10.89.99.30, but I can’t find the share using showmount -e 10.89.99.30 I have attached the cib.xml and cluster.conf files from my drbd cluster. I am just looking for a push in the right direction. William |
