RE: NFS equivalent of "cifs top"?
by Fox, Adam 12 Jan '07

Yeah, that's a front-end to nfsstat -l. There's also a lun_top in the ToolChest as well that does the equivalent for LUNs. It front ends the lun stat command as well as some others. -- Adam Fox adamfox(a)netapp.com _____ From: Charles H.

Check and see if you have a "cifs top" command in ONTAP. I'm not sure what release introduced it, but it's on my 7.2 simulator, but I think it's older than that. It has an accompanying option cifs.per_client_stats.enable option like the nfs one. -- Adam Fox adamfox(a)netapp.com _____ From: Jeff Mery [mailto:jeff.mery@ni.com] Sent: Friday, January 12, 2007 1:15 PM To: toasters(a)mathworks.com Subject: NFS equivalent of "cifs top"?

Re: Netapp support

Hi, Glenn: Third parties (non-authorized NetApp resellers) provide the full range of NetApp product and support services, with the principal exception of continuous DataOntap fixes and updates, and can provide a LOT of difference in pricing. Nevertheless, if and when required, unbundled software update contracts can be purchased directly from NetApp or an authorized reseller.

RE: Preventative/proactive filer maintenance
by Glenn Walker 12 Jan '07

12 Jan '07

I'd recommend the scheduled WAFL reallocates to help defrag. I'm curious about the fact they question the last time it was wafl_ironed - this looks for and fixes corruption, not poor layout. I'd start by monitoring performance - stats output\sysstat and statit. Perfstat (from the now site) is a good tool to collect a lot of data, but unless you've been working on filers for a number of years, it will be mostly gibberish (though some output is similar to what you'd find on unix systems).

NetApp support inquired about various details on the 810, such as the last time it was wafl_ironed, etc. Indeed, the 810 had spun in production for years with minimal admin intervention. Apparently this contributed to the performance hit we took during our data migration. My question to the list is what are some 'best practices' for caring-and-feeding of a 7.x filer, ala preventative steps to take within OnTAP in order to prevent said problem from happening again in the future.

We currently use this filer in production with windows 2000 and windows xp clients. I have had no user permission problems up until this point. The filer allowed us to join it to our domain and we can access the filer from windows clients and set AD permissions on folders in the file share using windows xp or 2000. I am guessing this is Microsofts way of making windows more secure or maybe a small protocol difference with CIFS in Vista that the filer is not able to deal with. BTW as I said I can connect to the filer with CIFS using accounts I explicitly setup in the filer, just not active directory accounts.

But that doesn't *replace* any of the 50GB disks, which is what I understood as the original question. The rules are different if you add a disk vs. fail out a disk. If you were to fail out one of the 50GB disks in your scenario, and only a 100GB disk was available, WAFL would only use 50GB of the 100GB disk and even if you failed out both 50GB disks, the two 100GB disks that replaced them would still be 50GB.
