What background process?

If kill -9 doesn't work and it's not a zombie, you'll need to reboot.

Hello,

i try to kill 9321 & 24635 but it won't.

The process still there.

I think this is cause why mount/umount could not perform

server-a:/var/opt/ignite (root) ps -ef |grep nfs

Time to reboot, they are hung on I/O.

Hi,

I am also facing the same issue .Is there any way without rebooting the server?

I am also facing the same issue.  Is there any way without rebooting the server?

If on 11.31, have you tried "umount -f" on the client?

Have you fixed the server?
