Re: 3020 Cluster: which one is management interface
by Linux Admin 03 Jan '07

so i can do level 1vif : multi1 + mutli2 level 2 vif: single1 (out of 2 multi) vlans: 2 vlans on top of single 1 in cluster config? Have this been done?

That's a good point.

Everyone has a challenge with high numbers of small files and to add to that challenge; you are using one of the slowest ntap gear out in the market. -----Original Message----- From: Thomas Bleek [mailto:bl@gfz-potsdam.de] Sent: Fri Dec 29 09:46:45 2006 To: Toaster Admins Subject: Snapmirror transferrates?? Hello, I wonder what transferrate I could expect for snapmirror volumes (an/or qtrees) between 2 FAS270 directly connected with Gigabit Ethernet. We use one filer as NFS backing store for our Mailsystem (Communigate Pro) with mdir mailbox format, so we have many small files here. I see abnormal high lags with really moderate sizes of the transferred data. For instance we need about 20 to 40 minutes to transfer 100 to 600 MBytes! The filesystems a 50% filled 250 GByte Volume/qtree with 10.3 million files (with 7 mio free inodes). so the average filesize is about 12KByte. We use Ontap 7.0.4 here and will upgrade to 7.0.5 next week. But I don't really have much hope that this will change the problem. Could anybody give me some data about his/her transfer rates? I really can't believe, that this slow transfers are normal. An repeatedly snapmirror status command on the filer shows this: at first the transfer startet and transferred about 68 MByte in 80 seconds. after that it paused for 15 minutes (output constantly "transferring 68MB done"). from minute 16 to 26 it says "transferring inodes". in these 11 minutes it transferred 225.000 inodes. after that it transfers data again. in minute 28 it has transferred 550 MBytes. after that one minute pause and then the status is idle. Has netapp/snapmirror a big problem with small files? I don't want to switch to mailbox format because I like the advantages of mdir (single copy mailstore, easier backup?) Thanks for any hints, thomas

RE: Addendum: ID in quota report showing up as 911-####
by Glenn Walker 29 Dec '06

29 Dec '06

My First Thoughts: The Adminis ID is (I'm just guessing here) a Domain Admin account - by default, these are also admins on the filer. All administrator accounts (in the windows world) show ownership as the builtin\administrators group (this is a Microsoft thing, not a NetApp thing). This means that ANYONE that is a member of this group will show files that they own as belonging to this group - no matter where they are located. It's highly likely that these files are scattered about your file system and not located in a single place.

How do I derive sysstat "Disk Util" percentage from SNMP data?
by Andrew Siegel 21 Dec '06

21 Dec '06

I'm trying to use SNMP to record the "Disk Util" percentage numbers that are given by the sysstat command. The MIB doesn't present this number directly. The sysstat man page defines "Disk Util" as "The disk utilization (percentage) of the busiest disk", but I can't find any OIDs from which I could derive this. Does anyone know what to read and calculate in SNMP to obtain this number? -- Andrew Siegel Head of Systems Blue Sky Studios, Inc. 44 South Broadway, 17th floor White Plains, NY 10601 914-259-6336 direct 914-259-6500 main 914-259-6499 fax abs(a)blueskystudios.com

V-Series with NDMP backup
by Ammar Zolkipli 20 Dec '06

20 Dec '06

Gents, Let me first explain the overall layout. I've got a D2D2T design. Both primary and secondary filers are v-series, and snapvaulted. We have 16TB of CIFS home dir data volumes backing up to tape via NDMP. And the tape backup is on LTO-3 running at sustained throughput of 20mbps, (F**king slow, I know). Does anybody have experience how to speed up NDMP backup? At this point, the LTO-3 is shoe-shining as the minimum sustained throughput on that drive is 40mbps. And also, does anybody have any experience with NDMP to tell us why this is happening? Thanks
