I have several PCs mounting its home directory as well as other data directories from a NFS server. Until now I was using good (?) old NFSv3. Today I tried a switch to NFSv4 in order to decrease locking the problems Firefox has with its sqlite databases being on a NFS filesystem. Quick notes:
- if you use (and need) ACLs (the default POSIX ACLs), do not switch to NFSv4. It probably will take ten more years to be fully working (the speed of NFS development seems to be close to GNU Hurd).
- if you modify the “Domain” entry in /etc/idmapd.conf, modify it on all clients and the server, otherwise all users and groups will be mapped to “nobody”.
- I don’t know yet if the Firefox locking problems are gone (I hope so …)

Dear Philipp,
we are fighting NFS firefox sqlite database problems and were wondering if we need to switch to NFS4: did you manage to fix the problems like that, or in any other ways?
Any suggestions greatly appreciated!
Thanks
Ciao
Pietro

I cannot say what exactly fixed the problems, the switch to NFSv4 or newer Firefox/sqlite versions, but since writing this post over a year ago I never had locking problems again. We are currently running Firefox 3.6.
