NFS has 2 mount types, soft and hard. http://tldp.org/HOWTO/NFS-HOWTO/client.html http://tldp.org/HOWTO/NFS-HOWTO/client.html Soft mounts report errors immediately, hard mounts hang. And for permissions, NFS provides everything under the sun that you could possibly need via ACLs. NFSv4 is a very modern protocol, much as SMBv2 is (not SMB though, it's awful). Linux has had NFSv4 for what, 6 years now, at least, and even v2 and v3 had some limited ACL support? http://wiki.linux-nfs.org/wiki/index.php/ACLs http://wiki.linux-nfs.org/wiki/index.php/ACLs

That's nice to know, it seems that we have the "hard" configuration at the lab and it's a real pain. Backwards compatibility, you know. For my mini-cluster we use SMB and couldn't be happier.

  Not sure what your lab's trying to be backwards compatible with (NFS has had those mount options since at least 1989), but whatever works for you :) It's a mount option on the client, not the server, so maybe you can change it yourself. http://www.ietf.org/rfc/rfc1094.txt http://www.ietf.org/rfc/rfc1094.txt

  In a lot of cases, hard is what you want. Some systems can't deal with fs errors very well, and it's better to wait than to risk data inconsistencies.
