[Klug-general] Tweaking NFS parameters

[Alan @ COMM-TECH]

Greetings,

Am having some nfs server/client issues and wonder if anyone can help.

Ubuntu Server 8.04, 10 workstations running 9.04

In summary, the server exposes /home via nfs, when a user logs into the 
workstation, they are authenticated via ldap on the server and their 
home directory is automounted. Full roaming desktop/profiles are the 
result, and a good one.

All works wonderfully apart from:

- User profiles in Firefox keeps getting corrupted daily. Need a restore 
of yesterdays backup to recover.
- Evolution stores get messed up when IMAP mailboxes get too large
- Openoffice is crashing and going into perpetual fire recovery cycles, 
requiring a nuking and recovery of home/.openoffice.org* folders

Seems like it's pointing to an unstable nfs. Does anyone know what 
mistakes I am making in the nfs parameters.

WORKSTATIONS SETUP:

/etc/auto.master:

  /home /etc/auto.home

/etc/auto.home

  10.1.1.2:/home/&/profile hard,intr,wsize=8192,rsize=8192,time=10,nfsvers=3
  ^^^
  (that's on one line)

SERVER SETUP:

/etc/exports:

  /home 10.1.1.0/24(rw,sync,no_subtree_check)

One other thing, nfsstat on the workstations shows stats for V3, nfsstat 
on the server shows statss for V2 AND V3. Can't see why server runs both...

Any ideas appreciated!

Alan
