Latency reporting
by Peta Thames 20 Jul '12

20 Jul '12

Hi all, I'm a bit new to OnCommand and its many variants so I'm after some advice. I need to start generating regular latency reports for management. I have an idea on what to do, but as dfm has changed so much but I'd like to pick the collective toaster brain. - What do you think is the best level to report on? Lun/volume/aggregate/controller/entire filer? - What's the best means of generating these reports? I don't have Insight Balance, just basic OnCommand manager/perfadvisor/console/dfm/probably100othersIdon'tknowof Thanks, Peta

find files owned by a particular user? (quota trouble)
by Randy Rue 18 Jul '12

18 Jul '12

Hello All, I have an IT user who's getting quota alerts despite only having a fraction of the default quota in his actual home folder. If I run quota report on his home drive this reports correctly. However, as he was previously a Desktop Tech for another division (they have their home drives on another volume of the same vfiler), a quota report for that volume shows him as right at the limit. I'm pretty sure there are files somewhere on that other division's home volume that he is the owner of. How can I find those files? Preferably without flipping the archive bit and needing a full backup of the whole volume? Hope to hear from you, Randy Rue

translate disk info?
by Mark Flint 18 Jul '12

18 Jul '12

Hi all, I'm trying to translate the disk identity given by the stats show command, into a system ID, and having some difficulty. The command I'm using is:- stats show disk:*:disk_busy which produces info like this:- disk:4C33D0CF:CC7E4D5B:0B46C331:A990D3B1:00000000:00000000:00000000:00000000:00000000:00000000:disk_busy:53% And I'd like to translate it into a 1b.24 or similar if possible. Thanks, `Mark Mark Flint -- The Wellcome Trust Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is 215 Euston Road, London, NW1 2BE.

ndmpcopy oddities
by Thomas Nail 10 Jul '12

10 Jul '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 And speaking of data migrations... I performed an ndmpcopy of a filesystem to move it off of a set of DS14 Mk1 shelves (72 GB FC drives, which are now end of support) to a newer set of DS14Mk4 shelves containing 300 GB FC drives. The problem is that after ndmpcopy has finished, the source and destination volume sizes are different: filer*> df -k old_vol Filesystem total used avail capacity Mounted on /vol/old_vol/ 547880960KB 401694484KB 146186476KB 73% /vol/old_vol/ filer*> df -k new_vol Filesystem total used avail capacity Mounted on /vol/new_vol/ 547880960KB 401639832KB 146241128KB 73% /vol/new_vol/ So we're looking at ~50 MB of difference between the two. After doing filesystem checks on both, I found that both contain the same number of files, all of which are equivalent in size. The directory structures are also equivalent, with one exception: one directory is 12KB on the source and 4KB on the destination. Another anomaly is that a 'df' of the filesystems on Solaris 10 show a difference of 16 files between the source and destination. /usr/SAG/db-backup (filer:/vol/new_vol/db-backup):292482200 blocks 19023148 files /mnt/old_vol (filer:/vol/old_vol/db-backup):292372920 blocks 19023132 files So, I know that ndmpcopy is a logical (not physical) copy of the volume, but how is that accounting for more files with fewer blocks? Is it an artifact of fragmentation and metadata changes in WAFL when the data is dumped? I don't have a good explanation for my customer, so I'm hoping someone here will have a quick and easy answer.

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
