We were having a 10-node cluster and reduced it to 4 nodes. On the cluster we did have some svm's using NFS. Each SVM's did have 10 lifs, 1 lif per node. As we reduced the amount of nodes to 4 with did want to do a cleanup of the LIFS, so removing IP-addresses... We did it using following steps:
- Adapt DNS so only 4 instead of 10 IP-addresses will be used
- We waited for 14 days and then brought down the LIF's
What happend?
- A lot of servers were not able to mount the SVM's anymore but i don't understand why, as mounts are done using FQDN...
Any idea's.... Does the NFS-server remembers the IP-address when doing the mount initially or .... ?
