slow dumps
by Rogers, Jamie 11 Nov '03

11 Nov '03

Toasters, I have an F760 running data ontap 6.3.1 with 4 FC-9 (7x32) shelves attached. I use Ultra 10 with a HP SureStore718 LVD autoloader for remote backups. I use rsh (rsh filer dump 0uf sunbox:/dev/rmt/1 /vol/vol1) via a cron job to run the dump. The Ultra10 and the filer are connected on a private network via 100TX crossover cable. Local file system backups (from the Ultra 10) to this tape drive go at about 4+ Meg/sec, great. The root volume of my filer and /vol3 dump at 4+ Megs/sec, this is great. However 2 volumes, vol1 and vol2, dump at 571Kb/sec. This performance is independent of the interface used, I get the same results using my 100TX or my gigabit. Likewise I get the same results when the dump is run from the filer, that is eliminating rsh. Sysstat looks normal during both dumps. The only difference in the volumes is the number of files, volumes 1 and 2 each have about 2 million files where as volume 3 has 1.2 million files and the root is about 10,000 files with out quotas. The data on volumes 1 and 2 consists of lots of small files and changes frequently whereas volumes 0 and 3 are pretty static. I have already cut the volumes up into 4 qtrees of 30G each. A quota report does not look out of the ordinary and no single quota tree has more than 950,000 files, see quota report below. What could be causing the dumps to progress so slowly? Any suggestions to speed up my backups?

Raid group and volume...
by Art Hebert 05 Nov '03

05 Nov '03

I have a volume called vol0 which shows 254gb of space. I believe it has 7 data disks (34.5gb) and 1 parity disk in raid group 0. There is also a raid group 1 that contains a 1 data disk and 1 parity disk. I don't think these disks are being used in the volume vol0. How do I tell if they are or aren't? If they aren't being used how can I get them added into vol0 as 2 data disks?

The interesting thing about this is that the behaviour changed in ONTAP 6.3 and beyond. ONTAP 6.2 had the volumes sorted so they always appeared in the same order for both a "df" and for SNMP.

Unfortunately, my answers may not be sufficient to satisfy your mental hunger. To be honest, I don't know exactly what the D8 does. I was informed that it fixes the snapmirror code. The error was found to occur only in our "specific" circumstance. So what was/is our circumstance? 1) F880 source snapmirroring 3 batch area volumes to an F820 target across a 20Mbit Ethernet WAN. 2) The amount of data change per day is high. Approximately 10-40Gb per volume. 3) We were experiencing poor throughput across the WAN link (carrier issue) and had to frequently abort the snapmirror and delete snapshots from the F880 source in order to prevent snapshot space over-running production data space. This throughput has since been addressed (before D8). 4) The F820 target panicked a couple of times and dumped to the ok prompt. One of the target volumes was found to be corrupt. It was difficult to say if the source filer caused it or the target filer developed the corruption independently. We had some cases open and ran wafl checks and scans on both filers as a result. No errors were turned up. 5) The crash dump file was ftp'd to NetApp. This lead to the 6.3.1D8 debug release. When I get some more time, I might read into it a bit further. For now, I am more than happy that they have addressed the issue and fixed it very quickly. We have not had any problems with 6.3.1 or the D8 releases.

Dear Sir, My name is William Ume, Presently, I am working in an African country. I got your contact via an online network and felt you may be willing to pursue this with me. This proposal may sound strange to you or probably you may even think it is a joke, because of lots of funny mails circulating over the Internet. Well if you do, I really understand, but honestly my friend, I am really handicaped, because this is the only means available to me to communicate to you. Honestly, I think you should give me a trial, I need your assistance and the deal is good. The deal involves the transfer of funds, safely abroad. For your role, you are to receive a percentage of the funds, based on a sharing formula that will be agreed by both parties. If you are interested in pursuing this further please contact me via e-mail so that I can furnish you with the relevant details about the origin of the fund and the modalities for the deal. Please send your response to my private e-mail williamume(a)indiatimes.com William.
