maximum agitation to a filer
by Willeke, Jochen 10 Mar '09

10 Mar '09

Hi toasters, does anybody have a clue whats the maximum agitation is, a filer can handle? Maybe there is an official statement from netapp?!? The background is, that our facility-department is planing to start some aktivities near to our datacenter and we are afraid of any impact and want to give them some limits. Thankful for any thoughts!

vmware ESX and volumes/aggrs
by steve klise 07 Mar '09

07 Mar '09

I was always under the impression you wanted to put as many disks into an aggr, then setup the volumes inside the aggr. Here is what we are doing, and I am just trying to see what others are doing, best practices, etc. We have an AGGR that we use for VMware sitting on a 6030 running 7.2.4 FCP. The aggr is ~ 9TB or so, usable and we have 1 volume that is ~ 5TB or so. We do not currenlty use SMVI (waiting for the budget to open) :) but we will use SMVI and hopefully snapmirror over to another filer. All VM's are windows (for the most part) The primary storage is still on 7.2.4, so no dedupe, or thin provisioning until we upgrade to 7.3.2 sometime this year. This is coming btw to a store near you... Pros/cons to creating smaller/bigger volumes: potentially easier to snapmirror less dedupe % if we create smaller volumes (less vm's, less dedupe) Is there anything wrong with creating 1 volume to 1 aggr and grow the volume to 80%? Am I missing something here? We are thinking of reducing our snap reserve as well. Yes, I have read the vmware best practices doc. VERY GOOD BTW.

The issue has to do with how locks are handled during snapshot commits, and other functionality that uses delta files. The fix has nothing to do with VMware tools. For ESX 3.5 updates 1 and 2, you need to install ESX350-200808401-BG (or a bundle that includes it). For ESX 3.5 Update 3, the patch is already there and you just need to activate it. To activate it, add the following line to /etc/vmware/config prefvmx.consolidateDeleteNFSLocks = "TRUE" and reboot. Details are in TR3428 http://www.netapp.com/us/library/technical-reports/tr-3428.html Enjoy!

The latest theory is that the fixes in the latest version of VMWare tools sorts it out. VMware don't have a firm idea of what's causing it in our environment, but we've seen numerous bugs based on the locking mechanism (which is different in NFS to iSCSI or FC).

Re: FCP Partner Path Misconfigured - Host I/O access through a non-primary and non-optimal path was detected.
by Angelescu, Silviu 06 Mar '09

06 Mar '09

Make sure ALUA is enabled on Solaris as well as on NetApp and set the cfmode to single image on NetApp. I suspect ALUA may be off on Solaris. If you installed the host utilities for solaris run "basic_config -ssd_set", "reboot -- -r", "stmsboot -e" (do not let stmsboot to reboot; use reboot instead in next step), "reboot -- -r". This should work.

I also see the same issue with Solaris server Ironically, I overheard my co-workers talking about this very subject outside my office just a few minutes ago. There are apparently still problems with ESX with Linux (and maybe Solaris) VMs where there is a minor hiccup and the pre-configured primary path is replaced by ESX with the alternate path. Unlike what happens when you do a VMotion, the OS is not stopped by ESX during this process -- all the VM sees is that the disks have gone away (albeit for a brief period of time), so they mark the disks as read-only and then you're hosed until someone logs in and reboots the VM or otherwise fixes it. I think this is caused by a disconnect with the multipathing done at the ESX level and no multipathing done at the VM level. I strongly suspect you'll need to install multipathing software at the VM level that is compatible with the multipathing used by your storage -- so, EMC PowerPath, if the underlying storage is on EMC, etc.... Even if ESX is doing multipathing just fine, that doesn't necessarily mean that the hosted VMs can also automatically do multipathing in a way that will work with what the storage vendor supplies, what ESX does, and so on. Our solution is that the storage is simply never allowed to go down, and we don't touch anything that is served to the ESX machines without first getting prior approval and coordination with the ESX administrators, as well as with the appropriate VM administrators. And when you have hundreds of VMs on a set of ESX servers in a single infrastructure which could potentially be VMotion'ed at any time from one node to another, that is a hell of a lot of pre-coordination. Even the slightest bump of a cable could do something that the storage or ESX doesn't like, they do their multipath thing, and then all the affected VMs on the box are screwed.

programs to stress/saturate nfs traffic on filer
by Roscoe P Coltraine 03 Mar '09

03 Mar '09

i want to generate and measure as much load as possible on a unix host via nfs to our filer to capture the max throughput the host can generate. we have used iozone but this does not generally saturate the server or the filer. what i am looking for is something along the lines of host can sustain X MB/sec throughput and at the same time measure the filers performance/response. im sure someone has a page with tools on this somewhere
