NFS share doesn't failover due to being busy
We are trying to implement a failover cluster, which hosts database and files on clustered NFS share.
Files are used by the clustered application itself, and by several other hosts.
The problem is, that when active node fails (I mean an ungraceful server shutdown or some clustered service stop), the other hosts still continue to use files on our cluster-hosted NFS share.
That leads to an NFS-share "hanging", when it doesn't work on the first node, and still cannot be brought online of the second node. Other hosts also experience hanging of requests to that NFS share.
Later, I will attach logs, where problem can be observed.
The only possible corrective action found by us is total shutdown and sequential start of all cluster nodes and other hosts.
Please recommend us a best-practice actions, required for using NFS share on veritas cluster server (maybe, some start/stop/clean scripts being included as a cluster resource, or additional cluster configuration options).
Thank you, in advance!
