How many spares? Best way to use extras?
by pdunkin＠lucent.com 24 Sep '03

24 Sep '03

Our F760 has 6 shelves and 42 36GB drives (running Data OnTAP 6.3.3 if that matters). Four volumes have been configured, with one RAID group in each volume; two have eight disks each, one has seven, and one that is mostly inactive archived stuff has four disks. That leaves fifteen (count 'em, 15) spares. All the volumes except the archive are at or near 90% of capacity, a point at which I understand performance starts to plummet, and the storage needs of the users of the three active volumes continue to increase. What is the optimal way to make use of the oversized pool of spares? Thoughts I've had: - Create a new volume, put new projects there, and maybe move some projects over from existing volumes, so everyone who needs it has room to grow. - Add disks to the existing volumes gradually as needed, to keep capacity under 90%. If I do this, is it better to add new disks one at a time or several at once? Is going over 90% really a problem, or is that just unfounded rumor? Other suggestions are welcome. Also, how many spares would it be appropriate to keep as spares? I've been told that one per shelf would be enough, but some postings in the archives indicate that that may be on the generous side.

Hey, toasters has been quiet lately, good to see some solid technical discussion on the agenda! The 90% issue. I have only ever seen it degrade performance from an application/user perpective when the volume is holding database device files and being pounded. For flat files that don't change much, I wouldn't stress. If you have large snapshots for say, snapmirror, then I wouldn't go above 80% just in case. Adding disk? Without sounding like a Netapp salesman, "the more the better". Never add one disk at a time. The rule is 3 minimum to provide better striping. Add one and you could see a significant performance hit as that disk thrashes away. NOW has more details on this. From a pure technical design and efficiency perspective, I like Jim's suggestion. If you can afford the disk, keep vol0 small and sacred, if you can't, then there is no reason why not to use the space. The major caveat is the full volume backups and restores. I would do some careful calculations based on what I know about my backup solution. If your daily data changes are large and your backup windows small, you will have some backup problems. Even though double disk failure is extremely rare as Jim points out, if you have SLA's that specify a strict full restore window for that volume AND the volume DOES die ............. I hope your restores are fast. Get your ducks lined up before you shoot with this one. I don't think backing out of the 1 volume will be as easy as going into it.

Best way to use extras? Let's start a warm thread. My two cents is to: 1. build a ten disk raid from the 16 spares and set raid size to 9+1 2. migrate one of your eight disk raid/volumes to it as a qtree 3. destroy unused eight disk/volume 4. build another ten disk raid from left overs and previous volume 5. add this raid to the previous ten disk raid/volume to make big volume 6. migrate the next eight disk raid/volume to big volume as another qtree 7. continue to destroy old raids and migrate old to new volume as qtrees 8. when you are done you should have one big volume of four 10 disk raids and two hot spare disks. I've had two disks fail on one system once in 4+ years and that was during the disk firmware upgrade that only temporarily failed them (had to power cycle). We have had several TB of data on NetApp filers at this sight over that period. Use qtrees for all your exports to control space usage instead of building several volumes/raid strategies. It's simpler and more flexible. You can reapportion the space with little pain and no raid or volume reconfigures just by changing quotas. Some may say "Whoa, you have to have a separate root volume!" I say "Baloney!. The only time I came close to losing a root volume was in the infancy of NetApp; we did have to reboot and use a different volume as root volume (I had copied the /etc to the non-root volume) because of a problem with the wack program, but even then we recovered the volume. Another concern might be that "We're afraid the root volume will get full!" which you can easily avoid by judicious and simple quotas. The only other thing I can think of is the time it takes to back up and restore by volume size. At 11:56 AM -0400 9/23/03, Patricia A.

non root volume etc was Re: How many spares? Best way to use extras?
by Jim Harm 23 Sep '03

23 Sep '03

When I backed up the root /etc directory from root volume to non-root volume, I did use rsync. About 2 years ago, that operation started crashing the filers because when some sensitive files were removed in preparation for replacement, the filer would crash and reboot even though it was a non-root volume that was being changed. I stopped rsync'ing and have not restarted that practice. We currently back up the /etc directories on all our filers to other systems. There may be someone on the list that can testify as to whether NetApp has made the non-root volumes more forgiving when it comes to /etc files being changed and removed. I didn't follow it for lack of time.

ASSISTANCE!!!
by MARTINS JOHN 20 Sep '03

Dear Brethen, As you read this, I don't want you to feel sorry for me, because, I believe everyone will die someday. My name isJohn Martins, a merchant in Dubai, in the U.A.E.I have been diagnosed with Esophageal cancer which was discovered very late, due to my laxity in carrying for my health. It has defiled all forms of medicine, and right now I have only about a few months to live, according to medical experts. I have not particularly lived my life so well, as I never really cared for anyone not even myself but my business. Though I am very rich, I was never generous, I was always hostile to people and only focus on my business as that was the only thing I cared for. But now I regret all this as I now know that there is more to life than just wanting to have or make all the money in the world. I believe when God gives me a second chance to come to this world I would live my life a different way from how I have lived it. Now that God ! has called me, I have willed and given most of my properties and assets to my immediate and extended family members and as well as a few close friends. I want God to be merciful to me and accept my soul and so, I have decided to give alms to charity organizations, as I want this to be one of the last good deeds I do on earth. So far, I have distributed money to some charity organizations in the U.A.E, Algeria and Malaysia. Now that my health has deteriorated so badly, I cannot do this my self any more. I once asked members of my family to close one of my accounts and distribute the money which I have there to charity organization in Bulgaria and Pakistan, they refused and kept the money to themselves. Hence, I do not trust them anymore, as they seem not to be contended with what I have left for them. The last of my money which no one knows of is the huge cash deposit of twenty four million dollars that I have with a Bank in Amsterdam. I will want you to help me collect this deposit and dispatched it to charity organizations.email me I have set aside 10% for you for your time and patience. God be with you. John Martins

RE: Running Postgresql with db on Netapp
by Blake, Delroy 19 Sep '03

What are the specs on your PC? Say you have an ATA 100 controller and a drive with 8MB ram you can probably get hit a 30MB/s transfer rate while if you are doing nfs over 100 BASET the best you can hope to do is 12MB/s. If you have a PCI 64/66 or PCI-X bus in You may hit transfer rates of over 50-60MB/S with GE in both filer and PC. When your PC needs to read and write data he just does it he does not have to create IP traffic every time. That means he has to do a little more work to transfer using jumbo frames will free up some of this overhead. Its an option to consider. You might also want to dd a 1 GB file over the network using different block size to see what performance you get. -----Original Message----- From: 'Aditya ' [mailto:aditya@grot.org] Sent: Monday, September 15, 2003 7:04 PM To: Maxwell Reid Cc: 'toasters(a)mathworks.com ' Subject: Re: Running Postgresql with db on Netapp On Mon, Sep 15, 2003 at 03:41:28PM -0700, Maxwell Reid wrote: > Is it possible to install a Gigabit adapter in the *BSD box and > filer?

I'd consider that, however I'm having a hard time believing that a PC a *stinkeen* plain-ol-IDE drive is doing better than my filer. I can blame (in order of cost of upgrade): - a configuration mistake - mount options - filer options - network hardware - nfs - pc hardware - postgresql and I'm slowly working my way down that list...(grin) I suspect that folks running Oracle/Informix with a filer aren't seeing more than a 10% performance reduction, otherwise very few would opt to do it, so I suspect that it works, it works well and I must be missing something...
