Questions regarding snapshots
by Steven Mandrake 04 Jan '07

04 Jan '07

Hello, Just a generic question. Can I run ndmp backups and run snapmirrors and snapshots at the same time? Will this affect my backups or snapshots in anyway? Integrity of the backup or performance? Thanks, Steve

RE: 3020 Cluster: which one is management interface
by Fox, Adam 03 Jan '07

There never was any requirement or designation of a "management" port in ONTAP. Most filers pre-3000 series had a single on-board 100Mb port that many decided would be a management port, but it possesed no special privledges or function other than it was the port that the filer would obtain its first address via DHCP if the filer booted and was not configured. For filers with multiple on-board ports, that port is the "e0a" port (same as the FAS 250/270). But that's really the only thing special about the on-board port. If you CHOOSE to make one of the ports a management port, you can, but you don't have to. You could use vlan tagging as specified below so you don't chew up a port. Or if by "management" port you just want a separate port to login to the port, consider using the RLM port (if your filer has one, I think you have to order a 3020 with one, but the 3050 and above have them standard) as the management port. Just a thought. -- Adam Fox NGS Tools Developer adamfox(a)netapp.com _____ From: Linux Admin [mailto:sysadmin.linux@gmail.com] Sent: Wednesday, January 03, 2007 6:01 PM To: Blake Golliher; toasters(a)mathworks.com Subject: Re: 3020 Cluster: which one is management interface Blake, Thanks!

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

03 Jan '07

Folks, Not familiar with 3020 series at all. I see 4 nics (e0a, e0b, e0c,e0d) on the back of each head. Does it mean I have sacrifice one to be management and only 3 are available as data? Have NetApp change things? Or can I used all 4 in single/multi vips? I was going to do e0a and e0c in single A, e0b and and e0d in single B, and Multi VIP C on top of Sinlge A and Single B. Not sure what to do about management. Thanks for help

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-####

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.

Addendum: ID in quota report showing up as 911-####

Okay... Had a major brain glitch. The accounts were deleted in Windows and that's why the name didn't appear. But now I have another question.

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

RE: Aggregrate snap reserve (again)
by Glenn Walker 19 Dec '06

19 Dec '06

I'm pretty sure that the aggr snap reserve is not needed for core dump - this is written to the 10% overhead space (or to spare drives, depending on how you've configured your filer), then when the filer comes back up and the 'savecore' is performed, it is written to the /etc/crash directory. As for the aggr copy command, that is news to me (you see how often I've used it). The one thing you did overlook: restoring an aggregate - not individual volume, mind you. This is the same concept as vol snap restore.

Core dump does not go into aggr snap reserve. During panic, core is dumped into a reserved area (the space chopped off by rightsizing) on one or more non-broken disks (outside of WAFL, since WAFL code runs in memory, which we might no longer trust depending on what went wrong and we're dumping it). During reboot, savecore (see the man pages and System Admin Guide) moves the core from reserved area to /etc/crash, where it can be picked up by the user or other process. I could be wrong about which disks it uses, but I'm sure it doesn't use aggr snap reserve.

RE: CF Disk Configuration Question
by Learmonth, Peter 18 Dec '06

18 Dec '06

This is completely supported. I would suggest putting loopback plugs on the unused ports. This was best practice on FAS900, but I'm not sure about FAS3000. The loopback plugs slightly improve takeover and reboot times by not having the filer wait for timeout on an open loop. LC loopback is X6521-R6 http://now.netapp.com/eservice/partDetails.do?partNumber=X6521-R6&produc tId=60420&rohsCompliant=R6 I know it says FAS270 on there, but it is used on any LC connector where loopback is needed. You can even use it to test Ethernet ports, although there is no value in terminating unused Eth ports. Enjoy! Peter -----Original Message----- From: Stephen C.

RE: iSCSI Cluster help
by Glenn Walker 16 Dec '06

Yeah - the default SCSI timeout in windows is 10 seconds - that should be increased to at least 180 seconds as a failback could take up to 3 minutes. If you have snapdrive, it does this for you automatically. FYI - leaving it at only 10 seconds could be REALLY bad if you have a performance hungry application like Exchange (verification plus normal operation could create havoc with undersized spindle count).
