Hi,
I have two FreeBSD servers mount NetApp NAS via NFS and run
under layer 4 switch to be redundant. I upgraded FreeBSD version
from 4.2R to 4.6.1-RC2, the panic crash still happen very often.
The messages I got from every crash are all the same which is about
"vinvalbuf: flush failed". Once the server-1 crashes, server-2 will
crash very soon. I guess there's some problems with accessing NFS
files on NAS, so when server-1 crashes, server-2 keeps accessing
the same file and then crahes, too.
So is there any suggestion? Does it help to upgrade to 4.7R?
PS: Both servers are with dual CPU with SMP enabled. I tried to
turn off SMP, but it didn't help anything.
Thanks!
Best regards,
Gareth
