Managers,
Yesterday I posted a question about netstat 'Ierrs' on an AlphaStation
255/233. The solution was to match the duplexing of the switch to the
network card. This did solve the 'Ierrs' problem and help the speed of
network transfers, but we are still not running as efficiently as hoped
for.
We have an AlphaStation 255/233 with a 10mbit card (I know we could
use a 100mbit card in it) and a large file holding directory. This
directory is NFS mounted on two different AS 2100s with 100mbit cards.
Users run processes that read and write from the NFS mounted location and
then load into the Ingres database. The AlphaStation 255/233 is now
reporting a large number of collisions (Like almost 50% of the output
packets), and on the AS 2100s the following messages are being reported
when the users are running their processes:
Mar 25 09:24:09 bubba vmunix: NFS2 server pluto not responding still trying
Mar 25 09:24:09 bubba vmunix: NFS2 server pluto ok
Mar 25 09:24:28 bubba vmunix: NFS2 server pluto not responding still trying
Mar 25 09:24:28 bubba vmunix: NFS2 server pluto ok
or,
Mar 25 09:45:10 athena vmunix: NFS3 server pluto not responding still
trying
Mar 25 09:45:10 athena vmunix: NFS3 server pluto ok
Mar 25 09:45:10 athena vmunix: NFS3 server pluto not responding still
trying
Mar 25 09:45:10 athena vmunix: NFS3 server pluto ok
I have NFS configured on all of the servers the same way - default
choices...
NFS_CONFIGURED="1"
export NFS_CONFIGURED
NFSSERVING="1"
export NFSSERVING
NONROOTMOUNTS="0"
export NONROOTMOUNTS
NUM_NFSD="8"
export NUM_NFSD
NUM_NFSIOD="7"
export NUM_NFSIOD
NFSLOCKING="1"
export NFSLOCKING
PCNFSD="0"
export PCNFSD
AUTOMOUNT="0"
export AUTOMOUNT
The NFS directory mounted has the follow entry in /etc/fstab on both AS
2100s:
/d_tran_at_pluto /d_tran nfs rw,bg,hard 0 0
Is there a better way to configure NFS, or some other parameter?
Is there something else I could look at to help determine my problems?
Any help would be appreciated,
Thanks in Advance,
