try this. vol options vol0 nosnapdir on should be able to work
This appears to completely disable the directory -- i can't even cd into it.
I've been on systems where you didn't see it in, say, ls, but you could still change into the directory:
$ ls .snapshot ls: .snapshot: No such file or directory $ cd .snapshot $ ls hourly.0 hourly.2 [snip]
However, our installation can't do that. Has anyone been able to get this behavior over NFS?
