is it possible to mount a vinum-fs on 2 hosts?

[Michael Schuh]

Hello,

i have a little problem.

I hav Host A   and    Host B  both are connected to an SAN
through an QLA2200 Fibre-Channel (man isp).
On the SAN are 14 Disks da0-da13 these Disks are configured
w/ vinum to an RAID 10 Filesystem.

Now i have the Problem i would make Host A to an PDC and
HOST B to an BDC. 
To be redundant in an fail of the PDC (Host A) i would have access to the SAN
from BDC (Host B).

Now i Know the Problem of an already mounted Filesystem.
I would mount the Filesystem on both Hosts, may i cannot update
the Filesystemdescriptors from Host A on Host B.

Give it an option or knob for these problematic situation,
or must i  junk through the Shell-Scripting-Hell with ping/pong...;-)

Can anyone help me?

Tahnks for your interrest an Help.

Greetings

Michael
