nfs

I've got server A and server B. B acts as an nfs server, A mounts from B.

Both are running on EC2.

Sometimes I have to shut down B and start a new instance (identical instance). After B is back up, trying to do anything inside the mounted directory on A (ls for example) just hangs.

I'm trying to set up a cron that checks the status of the mount, and remounts if anything is wrong.

Is there any way to check the status of a mount?
