hastart post hastop -all -force disables NFS share on the vcs cluster
Hi,
Had to do a hastop -all -force to make some config changes and restart a process. When I did hastart post the changes all was OK except the NFS share exported out through VCS SG went offline and had to manually restart it.
Any ideas?
This is a system I inherited where Share resource does not depend on NFS resource and NFS + NFSRestart resource have no dependencies within the service group. This I'm fixing right now but don't think if it has got to do anything with the hastop issue. I would have expected the share to stay on during the process
More info:
After going through Symatec docs, I've now changed the config as follows and now on a "hastart" post a "hastop -all -force", the share goes offline and almost after a minute, VCS restarts the NFS resource and then the Share resource. While the situation is better I still have a 1minute outage.
Also, is NFSRestart a requirement if so, preonline requirements a must as well. I don't see NFSRestart adding any value if Lock failover is not enabled.
This could be 5.1 version issue as I don't seem to hit this issue with 5.1Sp1
