5.2.1 blues
by Brian Rice 03 Mar '99

03 Mar '99

My client has a computing environment that includes six F630's, an F540, and an F330, all doing CIFS, NFS, and quotas. In January, we decided to get them all running the same OS revision, and based on the bug list we chose 5.2.1 as a target. So we upgraded one of the F630's to 5.2.1 in mid-January to see how it'd do. It did great, so Friday before last we upgraded the remainder of the filers from various 5.1.x flavors to 5.2.1. At midnight on Saturday night/Sunday morning, all but one of the filers panicked. The F630 that had been up for a month on 5.2.1 joined the group in panicking, but an identical F630, just upgraded the previous day with the rest of the group, did not. The next day, NAC technical support told us, even before they saw the dump, that this was bug 12363 ("Terminated DC connection causes crash in stub code") which is new to 5.2.1 and occurs when a CIFS-enabled filer loses contact with its domain controller. This bug is fixed in 5.2.1P1. We were skeptical of this diagnosis at first, since we hadn't had any known network events or DC events at that time, but conveniently a filer panicked again on Monday when we tried to delete a share. That data point plus NAC's report on Sunday's dumps, which confirmed their diagnosis of bug 12363, convinced us to begin a careful yet urgent move to 5.2.1P1. We installed 5.2.1P1 on one of the F630's that had panicked. No problems for the rest of the week. So Sunday we installed 5.2.1P1 on the rest of them. Two filers (one F630 and the F330) panicked Monday after we did a "quota on" on them. The panics occurred on the same failed assertion: "../common/wafl/quota.c:926: Assertion failure." (Because the "quota on" is part of a script that various folks run frequently, it took two panics before we drew a straight line between the "quota on" and the panic.) The panics recurred on attempt to reboot. We had to boot off floppy, leaving quotas off. So now we are running without quotas on the filers that panicked on 5.2.1P1. And we can't do a "quota on" on any of the others; I personally am even afraid of "quota resize". And we are faced with the difficult decision between regressing to 5.1.x (which wasn't a rose garden either) or waiting for a new 5.2.1Px. Either way, we've submitted the most recent dumps to NAC tech support, and we're waiting on a response. If you are thinking of moving to 5.2.1, I encourage you to think carefully. Brian

RE: Will F760 work with IBM ADSM backup system?
by Mohler, Jeff 02 Mar '99

Yes, and slower'n hell. NFS mounting is not ADSM the way it needs to be done. Williams has a -lot- of holes where EMC bailed out, and ADSM support is an unbearably large hole in the NetApp strategy here. Everyone loves it, everyone wants it, but can't go near it.

The ADSM folks are looking into the possibility of providing support for NetApp, but there is no commitment. This is still under evaluation. In the meanwhile, ADSM works with NetApp over NFS mounts and I believe over CIFS shares.

Dell Deal
by Simmons, Charlie 01 Mar '99

01 Mar '99

In response to Philip Thomas's question below: Dell plans to resell some of NetApp's filers. The products will be offered under the Dell brand and therefore will have new bezels. They plan to use their own disk subsystem with the filers instead of NetApp's, but this doesn't change the function of the product at all. It's still "Network Attached." Dell will continue to offer their own server attached products as well. All of NetApp's functionality, including Snapshot, should be available on the filers from Dell. Dell's focus for the filer product line is the Windows market and thus the CIFS protocol. We'll have to wait until they formally announce their products to see if they also offer the NFS protocol as an option.

We are using Netbackup on 5 filers with a StorageTek 9710 and a StorageTek 9730. After a few initial problems, we essentially have a "lights out" operation. ------- Kelly Wyatt, saskww(a)wnt.sas.com <mailto:saskww@wnt.sas.com> Integrated Solutions Consulting SAS Institute Inc. / SAS Campus Drive / Cary, NC 27513 (919) 677-8000 X4279 (Voice) / (919) 677-4444 (FAX) http://www.sas.com <http://www.sas.com>

Re: nightly.1 busy: snapshot rollovers not happening
by Mark Muhlestein 01 Mar '99

01 Mar '99

The best way to do this is to create a special snapshot specifically for the backup, then delete it when the backup completes. This avoids the problem of the snapshot being changed out from under you. And this can all be automated with scripts. See Paul Benn's message for a pointer to a description of how to do this.
