DOT 6.4.2P11
by Kerry Herschel 03 Dec '03

03 Dec '03

I need to upgrade a R150 from DOT version 6.4.1P1D1 to DOT 6.4.2P11 because of bug 102089/Disk spin up errors could lead to wafl hung panic. My system did a system panic and rebooted last week due to this error. I'm a little nervous though about upgrading to a non-GA release. Is anyone out there running this release? (Netapp claims 20 systems are running it). If so any issues with it?

Default units for quotas in 6.4.2P6
by Chris Thompson 02 Dec '03

02 Dec '03

We have just upgraded from 6.3.3 to 6.4.2P6 (now it is "GA") and suffered a nasty consequence. If an entry in /etc/quotas doesn't specify any of "K", "M" or "G" for the limit, e.g. 261 user@/home 81920 4000 then the units are taken to be bytes rather than (as before, since time immemorial) kilobytes. In the example the limit becomes 80 KB rather than 80 MB. We have a daily useradmin job that runs overnight, and among other things builds a new /etc/quotas from another data source and then does a "quota resize". Our users weren't too happy to have all their quotas divided by 1024 in one swell foop... I have added an explicit "K" now, of course. All the documentation I can find still claims that "The default for the disk limits and warning threshold is kilobytes", so maybe this is a bug. Or maybe it will be reclassified as a feature when NetApp get around to updating the documentation. Anyway, it's something anyone upgrading ought to beware of. Chris Thompson Email: cet1(a)cam.ac.uk

Large directory performance bug? F760/6.1.2R3/Linux/2.4.20
by Chris Miles 01 Dec '03

01 Dec '03

Hi, we have over 20 webservers running a web application and serving all the data off a Netapp NFS mount. Netapp CPU normally sits at around 20-40% and NFS response is good. Today we hit what appears to have been a bug of some sort. All of a sudden, with no apparent increase in client connections, the F760 CPU went to 80-90% and the load on all the webservers rose sharply (from approx 0.5-1.5 up to 15-20). The site response went down the drain (20+ seconds for a page that normally takes under 1 second). It appeared to be caused by the application doing readdirs (along with other operations: read/write/getattr) on a specific directory, which at that time held about 70,000 files. We fixed the problem by disabling the readdirs within the application and also reducing the number of files in that directory down to about 45,000. We don't know exactly which fix (stopping readdirs or removing the files) did the trick, but after that Netapp CPU dropped back to normal and the webservers were happy and the site responsive again. It appeared that the combination of all the operations on the large directory were causing the NFS clients to hang and the Netapp CPU to max out. Although at the same time, other NFS operations were still performing at a reasonable speed (ie, the whole Netapp was not locked up). Any ideas on a bug or limitation on either the Linux or the Netapp side with regards to large (70,000+ files) directories? Info: Netapp F760C ONTAP 6.1.2R3 Linux 2.4.20 (Redhat) Mount options: rw,hard,intr,vers=3,proto=tcp,rsize=32768,wsize=32768 Cheers, Chris -- Chris Miles http://chrismiles.info/

Maintenance on a filer with FCP connections...
by Don Hickey 01 Dec '03

01 Dec '03

When rebooting a filer that has SAN connections via FCP what is the "proper" procedure? Should all LUNs be unmounted from their respective systems first? Is a sync all that's required or is that even necessary? We have a few oracle databases on netapp LUNs and I need to upgrade the os and reboot. Just didn't want to shoot myself in the foot. thanks, -- Don

ndmp DAR veritas FP3
by Jerry 01 Dec '03

01 Dec '03

I was wondering if anyone is using DAR with Veritas which came out in FP3. I am currently upgrading from Maintenance Pack 3 to Feature Pack 3 (and eventually feature pack 5) to get the DAR feature, but I was wondering if anyone had any bad/good experiences to share with DAR and with upgrading veritas to support it.

a dying man's plea
by larry moore 29 Nov '03

29 Nov '03

Greetings to you and your family in the name of God. In my search for a reliable and God fearing person and having gotten your contact through prayers and painstaking efforts I have decided to seek your help in carrying out my last wish .My names are Larry Moore. I'm a 65 years old man and a British living in Dubai (United Arab Emirate). I was a merchant and owned two businesses in Dubai. I was also married with two children. My wife and two children died in a car accident six years ago. Before this happened my business and concern for making money was all I lived for. I never really cared about other values in life. But since the loss of my family, I have found a new desire to assist helpless families. I have been helping orphans in orphanage/ motherless homes. I have also donated some money for humanitarian needs in Sudan, South Africa, Cameroon, Brazil, Spain, Austria, Germany and some Asian countries. Only recently I saw on television the colossal loss of pro perties and livelihood of people in Canberra, Australia through fire. I was moved with great pity and compassion that I decided to make a contribution on assisting people over there. Before I became ill, I kept $12.5 Million in a long-term deposit account in a finance company . Presently, I'm in a hospital where I have been undergoing treatment for oesophageal cancer. I have since lost my ability to talk and my doctors have told me that I have only a few months to live. It is my last wish to see this money distributed to victims of this fire outbreak in Australia and other charity organizations. Because relatives and friends have plundered so much of my wealth since my illness, I cannot live with the agony of entrusting this huge responsibility to any of them. Please, I beg you in the name of God to help me collect the deposit and the interest accrued from the company in Canada and distribute it accordingly. Use your judgement to distribute the money and keep 5% of it t o yourself. Feel free to reimburse yourself when you have the money for any cost you incur during the process of collecting and distributing the money. If you are willing to help, please reply as soon as you can. May the good Lord bless you and your family. Regards, Larry Moore ---------------- Powered by telstra.com

You can make new disks from the NOW site, or you can go to maintenance mode ( be sure to get your license keys off it first ( rsh ) and then change the root password in the maintenance menu.

Root recovery without diskettes? Ulp.
by Professor Frink 28 Nov '03

28 Nov '03

I have a F740 with 4 FC9 7x36G shelves that I'm prepping for putting up for sale, and want to scrub the old corporate data off of it. Unfortunately, the root password is long since been lost, and the OnTap diskettes are not available (in the ex-wife's house in a bitter divorce, d'oh!). Is there any way to recover the root password somehow without the original floppies; I'm even willing to pooch all the data, since I want it scrubbed anyway. Any thoughts would be greatly appreciated. As it is, the unit is just one deafening white noise generating, air blowing, heating system. :( Thanks. _________________________________________________________________ The new MSN 8: advanced junk mail protection and 2 months FREE* http://join.msn.com/?page=dept/bcomm&pgmarket=en-ca&RU=http%3a%2f%2fjoin.ms…

IPSec on OnTap 6.4
by Garrett Burke 27 Nov '03

27 Nov '03

Hi, Was wondering if anyone has tried using the IPSec support in OnTap 6.4, either with or without the accelerator module? What sort of throughput are you getting with a particular filer/client spec and what sort of CPU load is the filer experiencing? thanks, GB ---- Garrett Burke, Service Implementation & Support Manager, Eircomnet. http://www.eircom.net
