Hi,

Possible, I dont know.
I always make sure my nfs servers are 100% up by clustering
them using HA and coda etc.
NFS is not only handling the voicemail store, but also the
data for a lot of other stuff so I never (cept for my mp3
and movies at home) deploy a single, standalone nfs server.

There are some options on mounting nfs, maybe you can try
soft.

Here is my brainwave:
make the complete directory structure for the voicemail
boxes on the asterisk box. Mount the nfs on
/var/spool/asterisk.
That way, when the nfs goes down your system will still have
the dir structure so asterisk will stay responsive.

OR......
make your nfs server HA ;)


Just curious, but using NFS like that, do you allow your main call servers handle voicemail or do you have a specific voicemail box for that? My boss's view on voicemail is that it's not mission critical for the phone system, we're mainly concerned about the level of uncertainty. It's better to have the phone system up and capable of dialing 911 with no voicemail, than lose the voicemail and risk losing actual call volume, plus the more HA the non-critical parts get, the more it costs.
