Hello All,
I've been a slient member for awhile, now I have a question/problem I
hope someone can answer.
I have an Oracle 9i RAC set up consisting of 3 database servers, two
apps servers and an EMC Clarion CX700 SAN. The servers are all running
Red Hat 2.1, the db servers are at kernel .34 and the apps servers are
at .49. I have 5 nfs mount points shared out by the first database
server. One mount point is for logs from the database servers (only
they connect to it), and the others are for miscellaneous files and
storage. We have been doing failover testing, shutting down a database
server and seeing if the other two keep processing requests. We have a
problem when we shut down the first database server, the one sharing the
nfs volumes. The other two servers just hang trying to connect to the
shares. I have tried every option in my fstab file to make the servers
stop trying to reach the nfs shares if the server is not available, but
nothing has worked. Here is one of the lines from the fstab file where
I mount a share:
shoprod1:/applcsf /applcsf nfs
soft,rsize=8192,wsize=8192,retrans=6,timeo=14,intr
Can you see anything wrong with this line, or can anyone suggest
something else to try. I can't even forceably unmount the shares with
an umount -f.
And if we try to kill any processes accessing the shares the kill
command just hangs (even with a kill -9).
Any suggestions?
Thanx,
