DRP plan

Anyone have a good Disaster Recovery Procedure for when the primary filer would fail? Our environment: OnTap 6.4.2 for F960 (primary filer) w/ R150 (nearStore) which contains snap mirrors of the F960 data volumes... all in a Windows 2000 AD domain. Filers are used by CIFS clients only (9x, NT4, W2k, XP). If the F960 would "die", we would want to break the snap mirror to the R150 and make this data read/write. Additionally, we thought we could give the R150 a Netbios alias name equal to the F960. We probably would have WINS and DNS changes to make as well and we would need to recreate the shared folders and quota settings on the R150. We do snap mirror the vol0 of the F960 to a volume on the R150. And, of course, how would you revert back to the F960 upon it's "rebirth". Anyone have experience or some "best practices" for such a process. Thanks! Paul M.

Another disaster recovery solution
by Jason Truong 01 Oct '03

01 Oct '03

Hello toasters, (thanks for the MRTG ideas) We have a F820 in our office which we currently back up to tape. We are in the process of moving some servers to a collo location for disaster recovery options. I wondering if there is a cheap IDE solution (or cheap SCSI) to running something similar to a NetApp. Like maybe a Linux machine with the ONTAP simulator. (does the simulator perform snapshots?) Basically, we If anyone has some good ideas/solutions/share their case examples, that I would really appreciate it. Also, I think many others can benefit from this. Thank you. Jason T.

The version would help, and also, you are not finding a default site, so it will go alphabetically to the next site. You seem to be dropping to NT4 mode by looking for those BDC/PDC's. This means that the AD insertion is most likely failing. > -----Original Message----- > From: Stephane Bentebba [mailto:stephane.bentebba@fps.fr] > Sent: Wednesday, October 01, 2003 2:56 PM > Cc: toasters(a)mathworks.com > Subject: Re: Active directory problem > > what about your Ontapp version ? > try to contact netapp support on this problem could help you a lot > > Thanigai Velan wrote: > > > Hi guys, > > > > Need help here.

Wrapping pktt trace?
by Edward Hibbert (eh＠dataconnection.com) 01 Oct '03

To catch an application problem, I want to leave pktt trace running on a filer...overnight. If I do, it'll fill it up. I know you can tell it to bound the amount of space it uses, but I think it stops tracing once it hits that. Is there any way to get it to keep tracing within a bounded amount of disk space, just overwriting old trace files? That way I would have the last few hours of trace.

Re: Dump performance
by Michel GELDENHUYS 29 Sep '03

29 Sep '03

Hi Duncan, I think you'll not see difference between native dumps and NDMP. Indeed, NDMP can ben seen as some kind of "remote control", so using NDMP to make backup with a Filer actually implies using dump. So NDMP is, for its most part, a mean to control dump operation, plus, and that's the added value, getting a catalog of the files backed up to easily recover them. For further info regarding how to tune tape backup, see here : http://www.netapp.com/tech_library/3066.html#6.

I'm particularly thinking of home and shared directories with millions of small files - the usual junk that accumulates on these types of shares with hundreds of users. I've seen amazing performance from dumps of Oracle datafiles, in the order of 90MB/s to three fibre-attached LTO-1s from an F840, but I know many small files will reduce thruput significantly. The question is how much and what would you do differently ? I'd be grateful for any numbers people could share. We'll probably use NDMP but I guess simple dumps would give a similar performance.

Dump performance
by Duncan Greenwood 26 Sep '03

26 Sep '03

Boring I know, but I'd be interested to learn what kind of backup performance people are getting for Windows/CIFS shares. I'm particularly thinking of home and shared directories with millions of small files - the usual junk that accumulates on these types of shares with hundreds of users. I've seen amazing performance from dumps of Oracle datafiles, in the order of 90MB/s to three fibre-attached LTO-1s from an F840, but I know many small files will reduce thruput significantly. The question is how much and what would you do differently ? I'd be grateful for any numbers people could share. We'll probably use NDMP but I guess simple dumps would give a similar performance.

Alternatives?
by Tuc 26 Sep '03

26 Sep '03

Hi, We currently have a customer with an F760 and 6 shelves of 36's, and an F720 with 6 shelves of 18's. We've had problems with both that of course should never have happened. About the only thing we came up with is another F760 with 6 shelves of 72's, vol copy to it, and then having the customer FTP to both to keep things in sync. This solution is a bit pricey for the customer. (About $47K) Has anyone looked at any of the IDE based solutions to replace a F760 class filer? We do about 4500 to 5K NFSops. Anyone had any other ideas? Thanks, Tuc/TTSG Internet Services, Inc.

C4.log?
by Gifford, Josh 26 Sep '03

26 Sep '03

Hello Toasters, In troubleshooting latency issues between our main site and a remote location, we have noticed a lot of traffic going to our filer and erroring out. Each machine in the remote location is trying to get to a file called \%username%\c4.log on a filer in our main site, but is unable to find it. Between all 20 users in this site, these events are occurring every minute or two. This traffic is coming from machines running Windows XP and 2000, some of the machines are in our active directory domain, some are in our NT 4.0 domain. I can't even find a single application outside of MS Office that they are all using. An example of the packet trace is provided below. Does anyone know what the c4.log is? Josh J.

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.

RE: How many spares? Best way to use extras?

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. Aaron -----Original Message----- From: Jim Harm [mailto:jharm@llnl.gov] Sent: Wednesday, 24 September 2003 3:03 AM To: pdunkin(a)lucent.com; toasters(a)mathworks.com Subject: Re: How many spares? 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

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
