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,
