Thanx for the info John. Unfortunately I can't use the Red Hat GFS, it requires v3.0 and we cannot upgrade to that yet. I have been pushing for it, but Oracle won't give me an definite answer as to whether their apps are certified for RH 3.0. We could go with Veritas' Storage Foundation for Oracle RAC, but that would require considerable change, and no one here knows the software. For the time being I'll probably have to go with a NAS device and make it as redundant as possible. -----Original Message----- From: wlug-bounces(a)mail.wlug.org [mailto:wlug-bounces@mail.wlug.org] On Behalf Of John Stoffel Sent: Wednesday, October 13, 2004 9:28 AM To: Worcester Linux Users Group Subject: Re: [Wlug] NFS question Don> I have an Oracle 9i RAC set up consisting of 3 database servers, Don> two apps servers and an EMC Clarion CX700 SAN.

This is the problem, the fact that you're using NFS in a clustered environment. Have you looked into using a Cluster Filesystem for your needs?

Getting a NAS box which provides NFS service to the DB servers and which has the require reliability you need. I personally like NetApps, but they can be pricey. But even with a single head, they're reliable and run well. I had one box with an uptime of almost 500 days. Oh yeah, UPS and Generator backup helps as well. *grin* You could get away with using another cheaper NAS, but since you spent the money on the SAN, why not just use that and GFS to provide the storage you need. Esp if most of the filesystems you provide are read (mostly) then you shouldn't have many problems.

NFS question
by Don Peterson Oct. 13, 2004

Oct. 13, 2004

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, Don Peterson Network/Telecomm Mgr. Sterilite Corporation

RE: [Wlug] NFS question
by Don Peterson Oct. 12, 2004

Oct. 12, 2004

I'm not sync'ing data, all three servers are writing logs to the share constantly (the applcsf share). We didn't buy Veritas volume manager, and we are not running Red Hat 3.0 yet, so I had to go with NFS for a shared file system. Believe me, I wish I didn't have to use NFS. I am looking into buying a NAS device to store the shares on, that way any of the servers can go down and the others won't be affected. But the NAS will still be a single point of failure. -----Original Message----- From: wlug-bounces(a)mail.wlug.org [mailto:wlug-bounces@mail.wlug.org] On Behalf Of Charles R.

I don't think there is any good solution. Using the "soft" and "intr" mount options is an extremely bad idea. Do it only if you don't care about losing/corrupting your data. Important data should always be mounted "hard,nointr". Personally, I avoid NFS like the plague. I only use it for readonly mounts (where soft,intr is less of a problem). Instead, I've standardized on rsync over ssh with RSA keys to get data between servers that need to be synchronized. _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

Howdy, This is Patrick from the Worcester Computer Co - Op, as you may or may not know we are holding an install fest on Saturday the 9th, for the purpose of installing Linux on old machines that will be donated to members of the community. This information was sent out by Andy earlier. I can send you more information if anyone needs it. The main purpose of this message is to ask who was planning on attending.

Internet service for newbies
by Patrick Sawyer Oct. 6, 2004

Oct. 6, 2004

This is in regards to the install fest that will be happening Saturday at the Worcester Computer Coop. These machines will be given to people with little computer experience / money. All they need for an Internet service is a very simple dial up. Has anyone tried Net zero for Lindows(linspire) and got it running under Linux? If not can someone recommend a good ISP. The cheaper the better. Thanks Patrick
