These are qtree snapmirrors, yeah? What are you trying to do? Make the targets r/w? Or resync?

All Flash FAS?
by Philbert Rupkins 20 Mar '15

20 Mar '15

Hi Toasters, Curious if anybody has experience with an all flash FAS deployment? We currently utilize Flash Cache and Flash Pool backed by SAS 15K and 10K drives but are considering an all flash FAS solution for our next system. What prompted you to go with an all flash config versus leveraging flash as a cache tier? What size SSD's are you using? Not interested in an E-series array as we depend upon the features of ONTAP. Also not interested in fronting an E-series array with an ONTAP system. I am aware of the 96 disk per stack limitation that goes along with FAS and flash. Cheers! -Phil

Flexscale lopri_blocks
by Edward Rolison 17 Mar '15

17 Mar '15

I'm currently contemplating caching on my filers. Specifically - setting those 3 flags on a flexscale cache appropriately. I _think_ given the workload I'm putting through one of my set of filers, enabling lopri_blocks is beneficial When I do, a 'stats show -p flexscale-access' gives me more disk reads replaced, and a better cache hit ratio. However I'm also looking at wafl:wafl:read_io_type and seeing that mostly - my cache module is only servicing about 10% of the IOPs going through my system anyway. Of the remainder, it's a pretty even split between disk/cache. And with 'lopri_blocks' set to on, my cache is churning data faster - but with it off, hit rate drops to <10%. I'm wondering if anyone can offer suggestions as to a good way to compare the two states - filer side. Are there any metrics I _should_ be looking at, that I'm not? Primarily looking at: - total IOPs (there's only one volume on this filer) - response time. - Disk utilisation (definitely increases when lopri_blocks is off). - cache stats as above. CP types - mostly this system is doing log_full CPs, and is getting a fairly steady stream of RW IOPs. Most IOs are NFS getattr and lookups though, which are mostly metadata. Of 100K iops, it's about 90% non-RW and 5% read, 5% write. I think I'm right in saying that these metadata IOs are going to be fairly small and thus served out of RAM (mostly) anyway. I'm also (re) reading TR-3832 - Flash Cache best practice. This is a little more vague than I'd like on figuring out whether 'lopri_blocks' will actually be useful. I _think_ they are based on a better hit rate, and a better reads-replaced rate. Any read replaced is one that's served from a faster tier, and is therefore 'better' objectively, right?

Re: SSLv3, POODLE, and NetApp...
by James Andrewartha 15 Mar '15

15 Mar '15

Yes, I had problems with OnCommand Host, ie my VMware backups stopped, when I disabled SSLv3 last week. Since it's no longer supported I just re-enabled it again. My guess is it's related to old Java? Also, while looking at it I noticed that the SSL certificates had expired some years ago but nothing complained or stopped working. James Sent from my Samsung device -------- Original message -------- From: RM <RM(a)richardmay.net> Date: 2015/03/15 05:41 (GMT+08:00) To: toasters(a)teaparty.net Subject: SSLv3, POODLE, and NetApp... My apologies if this has been discussed. I searched the archives and didn’t come up with anything. Customers are asking about disabling SSLv3 due to the POODLE vulnerability. Looking over the kb articles, NetApp’s guidance is rather sparse. Has anyone disabled SSLv3 in their storage environment and if so, what did you see? I have a preliminary report that the vSphere side of things has some issues when SSLv3 is disabled but I don’t have reliable details yet. Best to all, RM

Symantec Enterprise Vault + OnTAP based DR
by Momonth 12 Mar '15

12 Mar '15

Hello, I'm currently working on implementing DR for Symantec Enterprise Vault (EV), all EV data partitions are on NetApp filer (EV's SQL instance is out of the scope here), being accessed via FCP. I was hoping there was EV plugin for NeApp SnapManager, but it's not the case, also Symantec don't provide anything in that regard. I wonder if anybody looked at EV + SnapMirror integration? What were your approaches? My idea so far: 0. Setup SM jobs for EV volumes. 1. Set EV into 'backup mode'. 2. Trigger SM update for the EV volumes. Steps 1. ans 2. can be triggered from a powershell script, I think. Cheers, Vladimir

CDOT CIFS shares import?
by Basil 12 Mar '15

12 Mar '15

Does anyone know of a clean way to import CIFS shares? In 7-mode, I'd manipulate the /etc/cifsconfig_share.cfg directly if I ever needed to, but in CDOT, there's no such thing. I'm trying to plan a cutover from an EMC NAS to a Netapp SVM, and once we've got the shares on the Netapp configured and have done our final robocopy, I need to unjoin the SVM from the domain and rejoin it with the computer account of the old EMC. Doing this causes all the shares to be deleted. If there's no clean way to do this, I'll be building a command file of vserver cifs share create commands, but I'd really prefer not to have to. Thanks!

CMOD /etc/messages of SVM

Can I still mount what used to be /vol/vol0, aka root volume from NFS SVM and read /etc/messages?
