Hi, I set up HA NFS Server according to the HOWTO from linbit. Basically it is a clone of the NFS server and a clone of the root filesystem. A group of the Filesystem, the exportfs and the ip address depends on a DRBD and the root- exportfs clone.
See below for the configuration.
Lets say, the group run in node A and I put node B into standby everything
looks good. But when I set node B online again the NFS-group restarts
although it runs on node A where which is not touched by the restart of the
second half of the clone.
Any explanation? I tried to set the clone interleave and non-globally-uniq,
but nothing helps.
Thanks for any hints.
