NSF client listing
by Weasner, Matthew K 19 Oct '12

19 Oct '12

This is probably a silly question, but what is the most reliable way to get a list of NFS clients that have an export mounted? OnTap 7.3.3, and the share is exported R/W to the world.

I need to check if the firewall is open between filers on snapmirror ports. I cannot find a "telnet" command so I can telnet from fi ler to to filer on specific port. How do I check from filer CMD line if the ports on the snapmirror partner are open Thanks!

Expand SATA aggregate or buy SAS disks
by James Andrewartha 10 Aug '12

10 Aug '12

Hi, We have a small metrocluster with 2TB SATA disks in DS14mk2 trays, mostly used for VMware. We desperately need more IOPs, and are tossing up another 14x2TB SATA tray, which would have the benefit of just expanding the aggregate, vs 12 of 600GB 15krpm SAS (half a DS4243), which would give more IOPs but be more admin overhead since we'd have to move VMs amongst the shelves. Capacity isn't a problem, and when we built the metrocluster the ATTO 6500N fibre bridge wasn't available, so SATA was our only option at the time. We're getting quotes for both options, but does anyone have an opinion on expanding the SATA aggregate vs setting up a new SAS one?

ndmpcopy from 6.x to 8.1
by Jon Bousselot 23 Jul '12

23 Jul '12

Has anyone used ndmpcopy to migrate volumes from ontap 6.5 to 8.1 without going through any intermediate steps? The 8.1 docs say qtree snapmirror doesn't support source volumes prior to 6.5, so I'm looking for success stories on possible alternatives in case it doesn't work as advertised. rsync takes a long long time, but it works fine. This is all linux data, nfs. -Jon

FAS2240 Twinax Support
by Dan Olson 29 Jun '12

29 Jun '12

Hi All, We're currently in the specification phase of a project using a FAS2240 with 4x 10gbE ports. I'm trying to figure out if the FAS2240 supports "active" twinax from a Brocade VDX 6720. The Brocade ethernet switches seem to be relatively strange that twinax at <5M is active, usually it is only long twinax runs that require that. Anyone out there have a FAS2240 working with a Brocade switch via twinax?

OSSV being abusive of the secondary filer.
by Jeff Cleverley 27 Jun '12

27 Jun '12

Greetings, I'm running OSSV3.0 on some RH5.4 clients to a 6040 NearStore running 8.1 with 10G networking. The process works OK, but when I have an OSSV transfer running, the system load on the filer goes to 100%, it starts behaving very sluggishly, and the regular filer to NearStore backups start running very long, in some cases 2-3 days when they should complete in no more than 6 hours. I've gone through the installation and best practices guide and don't see anything about tuning the secondary. I've looked at sysstat during the load times and disk and network throughput are hardly above 60 MB/s. I know I can try throttling the backup, but it doesn't appear to be a throughput or bottleneck issue. Has anyone else seen this or is there anything I can do to help this? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

$BACKUP_PRODUCT <-> NetApp integration.
by Ray Van Dolson 27 Jun '12

27 Jun '12

Hello all; We are exploring a couple of different ways to integrate our backup product (CommVault FWIW) with our NetApps (N-Series to be exact). CommVault integrates by leveraging FlexClone and SnapRestore. This operates at the volume level and so we either grab the entire volume or nothing at all. No way to get granularity into specific files or folders. Due to licensing constraints, we can't just grab "everything". This may change in the future, but until then we're looking at several options including setting up dedicated flexvols where VM's which need backups are placed and other flexvols where VM's we won't back up are placed. CV also has integration natively with vCenter, but there are some performance downsides here. How do some of you out there handle this sort of scenario? Thanks, Ray

WORKAROUND: AutoSupport cannot connect to url https://support.netapp.com/
by Fletcher Cocquyt 25 Jun '12

25 Jun '12

Well, I followed Netapp support's recommendation to add a static route route add 216.240.18.16 <gatewayIP> 1 I post this followup under the category of WORKAROUND since the ASUPs are flowing now, but IMO the root cause is not determined (it should not be necessary to add this static route if the routing table is being obeyed) More info: Our firewall is set to LOG egress (outgoing) connections For the working node I could see the connections made from the default gateway net VIF But, on the problem node, this connection was being attempted from one of the other VIFs (not in the default gateway net) I've asked netapp support to review the fresh ASUPs to see what they might reveal about these apparent routing issues. thanks On Jun 4, 2012, at 11:00 AM, Jayanathan, David wrote: > I am very interested in what you find out.

shrinking snap mirror destination volume size does not return space
by Fletcher Cocquyt 23 Jun '12

23 Jun '12

I'm teaching our storage team to use the System Manager to resize volumes (both source and destination snap mirror volumes) Then one team member noticed this old issue - when the SM src/dest pair volumes are shrunk - the new size is not reflected on the destination - even after a SM update. Last year I wrote about this http://www.vmadmin.info/2011/04/shrinking-snapmirror-destination.html and the solution at the time was to break the SM to have the destination space reclaimed. But is there a better method? This script shows I have volumes with space reclaimable: ssh na01 -l root vol status -b | awk '{print $0" diff = "($3-$4)*4096/1024/1024" gb"}' Volume Block Size (bytes) Vol Size (blocks) FS Size (blocks) ------ ------------------ ------------------ ---------------- vol0 4096 78643200 78643200 diff = 0 gb pweb 4096 249036800 249036800 diff = 0 gb vm64 4096 810675078 805306368 diff = 20971.5 gb eweb2 4096 13369344 13107200 diff = 1024 gb sbackup2 4096 311951361 308543488 diff = 13312 gb vds 4096 191365120 180879360 diff = 40960 gb svm2 4096 563714458 563714458 diff = 0 gb sarchive 4096 562141594 549034394 diff = 51200 gb svm4 4096 629145600 603979776 diff = 98304 gb vb2 4096 2883584 2685440 diff = 774 gb cldb 4096 1184890880 1184104448 diff = 3072 gb cl2 4096 1848377344 939524096 diff = 3550208 gb thanks

Cluster mode - Market vs field
by Milazzo Giacomo 22 Jun '12

22 Jun '12

Hi all, I've recently attended an official event where people from NetApp in few words said: "DOT 8 7-mode has done its time, it's over, it has been a great os but It's now time to move and push DOT 8 Cluster Mode, everytime, everywhere..." and this also if with a simple two node HA system, including 2220! What do you think about? Also let us assume that cluster mode can (I add 'theoretically') do all what 7 mode does, don't you think that is quite premature to trumpet this out? Regards,
