Re: [Wlug] NFS question

by Adam Keck

Hello Don, True, but if you must use NAS for this, a redundant NAS device takes care of the single point of failure issue. Look at NAS solutions that provide clustered heads attached with redundant paths to redundant disks. Clustered Linux w/ SAN solutions would work or perhaps a blackbox like a Network Appliance filer cluster ($$$!) depending on your budget and time constraints. Moving the nfs shares off the first database server is important, because, in order to have redundancy in the cluster, members each must have the same function. Right now the first database server provides an additional unique function. Nothing can take over for it, as you have seen. -Adam On Oct 12, 2004, at 11:48 AM, Don Peterson wrote: > I'm not sync'ing data, all three servers are writing logs to the share > constantly (the applcsf share).

RE: [Wlug] NFS question

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

NFS question

by Don Peterson

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

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. You don't need to tell me you can just show up, I just wanted to know. We can use all the help you can give! Patrick Sawyer
