I checked; doesn't seem to be an issue:
# cat /etc/fstab
csddata7-vlan35:/vol/vol0/replica /replica nfs
proto=tcp,suid,rw,vers=3,proto=tcp,timeo=600,retrans=2,hard,fg,rsize=8192,wsize=8192
0 0
I'd be interested in any feedback on the settings. The connection
between server and NetApp is on a private vlan on a separate network
interface than the rest of the LAN. I'm not positive, but I think we
have jumbo frames (9K) enabled on that interface ... looks like we do:
# ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:09:6B:E6:33:B7 [...] UP BROADCAST RUNNING MULTICAST
MTU:9000 Metric:1
Thanks,
