I had a problem when Oracle used mounts that were not explicitly listed in exports. For example, I had mounted /vol/vol1/orafiles to /orafiles, but in the exports file on the filer I only had listed /vol/vol1. Everything was fine for weeks until I failed over. At that point, it was still mounted but it wasn't really there(permission denied, other weird messages) even though other similar mounts were fine and usable. I have since gone back and exported every directory that I mount to and I have failed over (and even survived some core dumps) without any further problems.

F85 retrofit ???
by Benoit Artuso 05 Sep '01

05 Sep '01

Hello, in my NOW console, i have a case opened called "F85 retrofit". I pretty sure that I never opened such a case and support(a)netapp.com does not answer my email. It really seems that NetApp opened a case behind my back to change something on our F85 (that works perfectly). Is there a problem with the F85 ? Does anyone know something more about that ? And, if there is such a problem, why NetApp does not tell me so ? Is it something that must be hidden ? I know there were some problems with the early F85 (they stopped selling them for 3 months !!!) but the marketing guy didn't know much more than "We don't sell this products until a 'we dont know' date". -- Benoit

Unexplainable unresponsiveness of F820
by mcope＠isisph.com 05 Sep '01

05 Sep '01

I've recently moved files from a F740 onto a new F820. This happened on Monday and on Tuesday morning the F820 suddenly stopped serving data. It became so unresponsive that I was unable to even get in thru the console. I got prompted for a password but it never got to a command line prompt. The Filer didn't appear to be excessively busy beforehand and the network connection (Gigabit) still appeared to be fine. Basically, the Filer appeared fine externally and the LCD panel showed that there were 0 ops a second. The only way I could get the Filer "running" again was to cycle power. The Filer has been fine since then. There were no messages in the syslog and it didn't dump a core file (I know now how to force it to dump a core for diagnosis), so NetApp tech support hasn't been able to provide much assistance or explanation. I've seen this same behavior twice on the the F740 in the last 2 months but that had been diagnosed as a faulty Fibre Channel controller seizing up when the workload got too high. Other than the actual data files, the only thing these two Filers have in common is Data ONTAP 6.1R1. I'm running 6.1R1 on two other Filers and have had no problems. It just seems very coincidental that I didn't experience this on the F740 until after I installed this version of ONTAP. Anyone else seen this behavior before or noticed any irregularities with 6.1R1 (I'm not running in a cluster so the latest updates/bug fixes don't appear helpful) Thanx, Michael Cope UNIX/Linux Systems Administrator Isis Pharmaceuticals mcope(a)isisph.com UNIX is very user friendly... it's just highly selective about who it makes friends WITH!

Volumes unmounting

Hi All We have an oracle Database mounted on an E4500. We then have 2 filers Filer A has volumes /vol/u01 /vol/u02 /vol/u03 Filer B has volumes /vol/u04 /vol/u05 /vol/u06 All volumes are mounted on this one E4500, but what we have expereienced is that from filer A, the /vol/u01 mount point UNMOUNTS periodically. About 10 times a day. Yet the rest of the volumes dont. Has anyone experienced this?

We are not using automounter for this volume. The Oracle Binaries are on the local disks as opted by our Oracle DBA's The u01 volume has the Archive Logs so oracle does not fall over with the loss of this volume. However, oracle does pause while the volume is down. I have done a snoop on the system and it looks as though there is an NFS mismatch, whereby its mounted up with NFS version 3, but some time later, it changes to NFS version 1 and then unmounted. This definalty looks like fun. -----Original Message----- From: Brian Tao [mailto:taob@risc.org] Sent: 05 September 2001 03:44 To: Noll, Kevin Cc: 'toasters(a)mathworks.com' Subject: Re: Volumes unmounting On Wed, 5 Sep 2001, Noll, Kevin wrote: > > All volumes are mounted on this one E4500, but what we have > expereienced is that from filer A, the /vol/u01 mount point UNMOUNTS > periodically.

Even with automounter, assuming Oracle is actually running, Solaris tends not to umount filesystems with open files on them. I'm guessing your Oracle binaries and config files are in /u01/app/oracle/product/etc, etc. and so the loss of that filesystem pretty much means your database has to be shut down first. -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't" ******************************************************************************************** " This message contains information that may be privileged or confidential and is the property of the Cap Gemini Ernst & Young Group.

RE: Snapshots of QTREEs
by Lenzer, Mike 05 Sep '01

I can't speak for the other DBs, but in Oracle you would try and use 2GB or 4GB datafiles. If there's a corrupt block, you'd only need to goto .snapshot/hourly.0 and copy that one 2GB file back to the active filesystem, then start a point-in-time recovery. SnapRestore when you have a major meltdown or when small number of spindle volumes don't matter, such as in development environments. -----Original Message----- From: Egner, Michael [mailto:Michael.Egner@netapp.com] Sent: Tuesday, September 04, 2001 3:27 PM To: Jamey Maze; Jay Newton; 'toasters(a)mathworks.com' Subject: RE: Snapshots of QTREEs Correct.

But you can place several DB instances, in seperate qtree's, into hotbackup mode and take a snapshot of the entire volume. Takes less time than to shutdown your DB and "waste" one snapshot per instance. Hence, you can consolidate more DB's on a larger volume (read: more spindles) and increase performance overall. Be sure to keep your redo logs on different volume! If you have different *types* of DB's, group them by how fast you can place them into a consistent state and then take one snapshot. /M/ -----Original Message----- From: Noll, Kevin [mailto:Kevin.Noll@capgemini.co.uk] Sent: Tuesday, September 04, 2001 1:48 PM To: 'Jay Newton'; 'toasters(a)mathworks.com' Subject: RE: Snapshots of QTREEs Good question.

Snapshot/SnapRestore works on volume basis and not on qtree level. 31 Snapshots mean, you can have 31 backup copies of the volume using Snapshots. Hope this clarifies!! --Sri -----Original Message----- From: Jamey Maze [mailto:maze@cs.utk.edu] Sent: Tuesday, September 04, 2001 1:30 PM To: Jay Newton; 'toasters(a)mathworks.com' Subject: Re: Snapshots of QTREEs When you create a snapshot, it's the entire volume.
