Hello all!
Some of our offices are NFS mounting main office filesystems
using VPN (Cisco VPN, Lan2Lan).
We're using direct maps, client /etc/auto_direct:
% cat /etc/auto_direct
/staff -rw odin:/staff
/smod -rw odin:/smod
/common -rw odin:/common
/projects -rw freya:/projects
/testdata -rw freya:/testdata
/seisdata -rw lom:/seisdata
Main office file servers:
odin & freya are Solaris 9, Sun 280R. Filesystem is vxfs.
lom is an Sun Ultra 10, Solaris 8, ufs.
Clients:
Ultra 10 & SunBlade 100, Solaris 8 and 9.
The problem is that the clients looses their NFS connections
from time to time, leaving the mounted filesystem unavailable...
From client saturn:/var/adm/messages:
Jan 31 13:56:30 saturn nfs: [ID 563706 kern.notice] NFS server freya ok

The client does not manage to restore the mount afterwards, we'll have
reboot the client... The servers are up and running all time time.
