How do I get NFS locking to work? (And why doesn't it "just work"
anyway?)
I am unable to use monotone properly over an NFS mount because it very
sensibly tries to lock its repository before modifying it.
My only clue to the problem is messages that keep being reported by
logcheck:
> Security Events
> =-=-=-=-=-=-=-=
> Dec 11 12:15:34 lovesong kernel: nsm_mon_unmon: rpc failed, status=-13
> Dec 11 12:15:34 lovesong kernel: lockd: failed to monitor 172.25.1.11
> Dec 11 12:15:34 lovesong kernel: nsm_mon_unmon: rpc failed, status=-13
> Dec 11 12:15:34 lovesong kernel: lockd: failed to monitor 172.25.1.11
etc. etc.
I have not installed a firewall between the two machines.
The server is 172.25.1.11, aka "april", an AMD-64 runnin etch (updated
yesterday)
I have installed the nfs-kernel-server package, version 1:1.0.10-4
The client is 32-bet AMD machine running sarge.
Here's the output of some status-reporting commands, in case they might
be useful. Should I provide anything else?
