- Yes. NFS is essentially stateless. If the server reboots in the middle of
- an NFS operation, the client will pause until the server reboots then
- continue like nothing happened. Unmounting and remounting should not be
- neccessary.
-
- Stale filehandles can occurr when two or more computers are trying to
- use the same file. If machine 1 asks for the filehandle for "/tmp/foo"
- then, before it can use it, machine 2 deletes /tmp/foo, then when machine
- 1 tries to use the filehandle, it will get a stale filehandle error.
- Obviously client cacheing can make this problem worse.
