How mixed are you?
by David N. Blank-Edelman 22 Feb '10

22 Feb '10

Hi- I realize this may be a simple question, but I don't think I've ever seen an answer to it. We've been mulling over the idea of trying to reduce or eliminate the use of mixed-mode qtrees at our site because of some of the hassles they cause. One big question is how much our users would notice a change like that which leads to my real question: is there any clever way to determine just how "mixed" a mixed qtree is? (i.e stats on which way parts of it have flipped)? -- dNb

OSSV and Protection Manager
by steve klise 17 Feb '10

17 Feb '10

Current setup: Windows 2003 clients with OSSV agent 2.6.1 and host agent 2.7: V31xx series Filer all licenses needed Doing some testing with OSSV. I have the policy backup from primary to backup and keep for 30 days via Snapvault... I then snapmirror the volume over to a FAS3170. Pretty basic stuff. Question 1: I backup the guest. It takes about 1 hour, and PEGS the CPU of all VM's tested so far. I am not backing up the vmdk option, just the file system walk. No biggie to be honest. Here is the kicker. If I add a hard drive after I have done my initial backup/basline, the protection manager does not create a new SV relationship and protect the new resouce. I then go into NMC, Host tab, OSSV, select my test host, click ok the paths tab at the bottom, and it see the new drive, and SHOWS IT AS PROTECTED. Wrong!! I take a backup to see if a relationship is created, but is not. Very bad design. I would expect to see the resouce as unprotected, or give me some sort of alert. Maybe I am wrong. Am I missing something here? I legacy backup client would automatically pick up the new drive. Maybe I need to check something that is not obvious. Question 2: I have about 80 windows servers to backup. The thought was to put all the clients in 1 volume. I am expecting around 1 to 1.5TB of data. Maybe 30 of them will be VM's. I am concerned that although the 1st backup is the most intensive, will this impact if I kick off 30 VM's and the CPU's hit the roof. Not good I would guess, but anyone have any thoughts, opinions, I would love them. So far I have ~ 10 windows boxes. Seeing 25% dedupe. Love it. Sorry for being so verbose. Any help is appreciated. -- View this message in context: http://old.nabble.com/OSSV-and-Protection-Manager-tp27557891p27557891.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

Windows Groups and Quotas
by ifstat 10 Feb '10

10 Feb '10

Hi I know in the past Windows Groups where not supported for quotas only UNIX Groups are, this is true upto ONTAP 7.2.6.1. Does anyone know if this has changed in newer ONTAP versions or even if there is a plan to modify it? Also is there an alternate solution to enabling quotas for Windows Group, i.e. possibly using the usermap.cfg file Thanks -- View this message in context: http://old.nabble.com/Windows-Groups-and-Quotas-tp27527110p27527110.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

RE: Changing a LUN type
by Page, Jeremy 10 Feb '10

10 Feb '10

It can be pretty signifigant, it's not as well documented as VMDK misalignment but I'd expect similar numbers. It looks like the Solaris configuration shouldn't be an issue, it's got a larger offset but still aligned the same way as an AIX LUN. ________________________________ From: MRWILLIS(a)UP.COM [mailto:MRWILLIS@UP.COM] Sent: Wednesday, February 03, 2010 10:49 PM To: Roach, Steven; Page, Jeremy; toasters Subject: Re: Changing a LUN type Anyone ever get an IO performance delta on the misalignment created between the file system and the LUN?

Once it is created, I don't think you can change the LUN type, you would have to create a new one (same size) with the correct LUN type and copy over the data.

Ops Mgr/DFM Monitoring of CPs
by Fred Grieco 23 Jan '10

23 Jan '10

Does anyone know a good way to monitor Consistency Points and disk utilization in newer versions of OpsMgr? Or another way? These correspond to "CP ty" and "Disk Util" on a sysstat -x output. In previous versions of DFM and Management console (3.6 and 2.2), Management console had View under the logical views called "storage system - CP Details." It's not listed anymore in version 3.8. This was very handy, as high back to back CPs corresponded to performance issues we had. TIA, Fred

RE: Autosupport post - soo_write Failure

Hi, tested myself, the deletion did not solve the problem, sadly.... Searching for other solutions besides rebooting the system. Regards Jochen -----Original Message----- From: Willeke, Jochen Sent: Monday, January 11, 2010 4:16 PM To: toasters(a)mathworks.com Subject: Autosupport post - soo_write Failure Hey Toasters, I do have a question regarding a problem with autosupport from one filer. We use the post-method, due to mail-delivery-restrictions. Since some days we do see error-msg like these: [filername: asup.log.socket.err.post:error]: soo_write failed in autosupport post due to the error - Resource temporarily unavailable. Sadly this seems to be related to a bug, which needs a reboot which cannot be done in the next days. I found out that there are two files under /etc/log/autosupport which have the ending .post. Those files are the directly from the point in time when autosupport stopped working and start spaming the messages-file. My question is, are those files the blocking point, and can the deletion of the files solve this issue?? The files do have size 0kb and now content. Anybody ever come across this?

Re: SnapMirror for data migration within the same controller
by André M. Clark 15 Jan '10

15 Jan '10

So after trying a wide variety of things there was nothing that I could do to prevent snapmirror from using the loopback adapter for in controller snapmirrors. I really wish that 7G had the volume move command like GX. Thanks anyway for the suggestions.

SnapMirror for data migration within the same controller
by André M. Clark 15 Jan '10

15 Jan '10

Is there a way to perform a SnapMirror migration within the same controller without using the internal loopback adapter (~40Mbs). I have a situation where I need to migrate close to 6TB of data (multiple volumes) off of older smaller drives to larger 300G drives. Ideally I'd like to use SnapMirror multiplexing, however, I'm not sure that, even with direct connection between interfaces, this would even work (I'm thinking that the internal loopback would still take over). I don't want to do multiple snapmirrors (orig. controller> temp controller> orig. controller) but this may be my only path in order to get the speed that I need for the transfer. Any ideas?
