Re: Unexplainable unresponsiveness of F820

When I have run into the bug, it didn't seem to have anything to do with how busy the filer was. It *did* seem to be related to pending output on the telnet connection. So, if you connected, ran a command, and then closed the telnet connection while the filer was still sending results, the filer would freeze. Another scenario is when "console log" messages randomly stream from the telnet conneciton. Closing the connection while the console logs message is being written triggers it also. It interesting that you mentioned "Big Brother", because I never hit the bug while actually typing interactively via telnet. It was always via some automated telnet connection ( Expect, Perl, etc). I guess a human typing always tends to wait before sending the <ctrl-D>, while the scripted connections aren't anticipating "extra output". == Kerry >>> <mcope(a)isisph.com> 09/05/01 04:46PM >>> Kerry, Thanks for the info. I use Big Brother (bb4.com) to monitor the Filers. One of the things it does every 5 minutes is open and close a telnet session to test telnet. It's a pretty ugly method because it just kills the telnet session as opposed to closing it. The problems on the previous Filer only manifested when it was getting hammered. I've been using Big Brother for a number of months now and haven't had any problems keeping telnet sessions open to a Filer.

I've run into a bug with the telnetd daemon on the F820. Closing a telnet session to the filer while it has pending output sometimes causes the whole filer to "hang". This is occuring on 6.0.1R3. I did find some related bugs in the knowledge base, but I've resorted to not using the telnet interface for now. == Kerry >>> <mcope(a)isisph.com> 09/05/01 10:46AM >>> I've recently moved files from a F740 onto a new F820.

netapp bad disk bug
by Collin LeGault 05 Sep '01

05 Sep '01

Hey everyone, I have a couple of netapps that are doing this same weird thing. They both are reporting a bad disk, and when you replace the disk, the red light comes on for the new disk, and the netapp marks it as a broken disk. They are F760, running 5.3.5R3 of ontap. Someone thought we should take a down time and reboot them to see if that fixed it, but I wanted to avoid the huge amount of work that would be and see if anyone here has any suggestions. If you need more information about the filers to figure this out, let me know. Thanks in advance, coLLin LeGault

BCS VS ZCS Zone Disks
by Noll, Kevin 05 Sep '01

05 Sep '01

Hi All We have 9 x F760 Netapp Filers, 4 in Cluster Mode and the 9th one is what we have reserved for Snapmirror. We currently snapmirror volumes from these 8 filers to the backup filer. However, All existing filers have the old FC9 Disk Shelves with 36 gig disks in, and the new F760 Backup Filer has the new DC14 Disk Shelves with 72 gig drives. What should have been a disk for disk snapmirror configuration, either by having 36 gig to 36 gig or 36 gig x 2 to 72 gig disk, has become more complicated as the new disks have a different Zone. The new zone makes the new 72 gig disks slightly smaller than 2 x old 36 gig disks. I was wondering if anyone else might have encountered this problem yet, and if there is any workarounds as to disk zoneing, etc etc. Thanks KEVIN -----Original Message----- From: Jay Newton [mailto:jnewton@chkenergy.com] Sent: 04 September 2001 21:05 To: 'toasters(a)mathworks.com' Subject: Snapshots of QTREEs Is there a way to snapshot an individual QTREE from command line or must it be the entire volume.

Somehow, a comparison of block for block of the zcs disks and the bcs disks come out with zcs having a slightly bigger size. Under normal conditions, this small size difference would not really be seen, but if you try to do a snapmirror between the two, having the bcs disks as the destination, the filer complains that there is not enough space. So far we have had to work our disks with this formula. If a volume size of BCS disks is 4 = 1 parity 3 data (36 gig disks), then BCS disks would have to be 3 = 1 parity 2 data(72 gig disks. If a volume size of BCS disks is 9 = 1 parity 8 data (36 gig disks), the BCS disks would have to be 6 = 1 parity 5 data (72 gig disks instead of 5 = 1 parity and 4 data. So hence 4 data 72 gig disks are smaller than 8 36 gig disks.

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

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.

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 can't speak for the other DBs, but in Oracle you would try and use 2GB or 4GB datafiles.

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.

As far as I am aware of, a snap shot is ONLY Per VOLUME. -----Original Message----- From: Jay Newton [mailto:jnewton@chkenergy.com] Sent: 04 September 2001 21:05 To: 'toasters(a)mathworks.com' Subject: Snapshots of QTREEs Is there a way to snapshot an individual QTREE from command line or must it be the entire volume. I have a volume set up for databases and I want to snapshot from command line individual QTREEs that represent different types of databases. Any help would be appreciated!

When you create a snapshot, it's the entire volume. But with 6.x, you've got 31 snapshots to play with so you can use different snapshots for different databases. Make sense?

Oracle I/O block size tuning
by Brian Tao 03 Sep '01

03 Sep '01

Our senior DBA asked about Oracle's block size and I/O chunk size settings... are there optimal settings for the two values when running over NFS to a filer (a pair of F740's in our case)? Our Oracle instances run on Solaris 2.6, talking NFSv3 over UDP to the Netapps with 32K block sizes. My first reaction was to say "you don't need to tune this", but what do people use? It sounds natural to me to use 8K block sizes and an I/O chunk size of 4 to take advantage of the 32K NFS reads and writes. Does it make a difference? -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

My Earlier e-mail to Toasters
by venkatesh sampath vankipuram 02 Sep '01

02 Sep '01

Hello, First of all I aplogize on e-mailing my resume to this mailing list on June 9-10 2001. I would bring to attention those who ridiculed my e-mail and making it sound real foolish, that maybe you also were looking for ajob one day and you too have your bad days. You did not fall off from the sky with a cushy desk job which you might be having now. I feel embarassed on being openly ridiculed in a company mailing list. Maybe I should talk to the "right" people ??. to Mr.Fred Berfl, maybe you are not a high powered technocrat, but i am sure you probably know how to use a mailing list to abuse someone else !. You dont have to organize a fundraiser to transport me to Cambridge,UK. Try e-mailing your thoughts about some one superior than you and pick on some one your own size. I am sure you are diligent enough!. Mr.Chris thompson, the same applies to you too. I respect Mathworks as being a great company and I dont want to be bullied by some people who think they are superior than others.Its a pity that this mailing list has characters who have utter disrespect for fellow human beings and their education and who want to display their superiority at every chance they get. I felt this e-mail was necessary to get my point of view across and I refuse to be treated like this for a small mistake of mine. I apologize once again for my unsolicited e-mail on June 10,2001 with subject "Resume" Hope my email drills some sense into some thick skulls ! Venkatesh

RE: Mass chown + preserve NT ACLs

Brian, You could use a third party NT tool like Small Wonder's "Security Explorer" to backup the NT ACL's on the whole tree then restore them when you have completed the uid and gid changes.

Brian, I believe it depends on what you want to be as a result at the end. If you'll flip the qtree to ntfs, do the chown, you will end up with ACLs. What do you want the files to be at the end - with or without ACLs ? Eyal. ----------------------------------------------------------------- eTraitel - I'm the new eBuzzword around !!!
