vol clone split
by Chris Hague 12 Oct '18

12 Oct '18

Hi Toasters, I have a number of volumes running from a common snapshot and would like to split them out. All these volumes are snapmirrored to our DR site. However, when I try to perform a vol clone split, it complains about an in-use snapshot. Reading further, it appears that the split will delete all snapshots, so doesn't like the snapmirror snap. What is the best way to split these volumes? Ideally without having to re-baseline \ lose my snapmirror destination volume \ snaps. ONTAP v9.1P2 Error below; Time Node Severity Event ------------------- ---------------- ------------- --------------------------- 8/30/2017 09:02:17 filer1 INFORMATIONAL mgmtgwd.jobmgr.jobcomplete.failure: Job "Clone Split" [id 6716] (Split vol1) completed unsuccessfully: Volume has locked snapshots (1). 8/30/2017 09:02:17 filer1 DEBUG wafl.config.req.error: Config request 'VV_CONFIG_REQ_CLONE_SPLIT_START' by WAFL for volume vol1 is not being processed because of the error: '387 - CR_VV_VOLUME_SNAPSHOTS'. 8/30/2017 09:02:17 filer1 NOTICE wafl.vv.clone.splitBusySnap: Volume 'vol1 has locked snapshots, not splitting.

Chicken/egg dillema doing a hardware upgrade on a FAS3250
by Jan-Pieter Cornet 20 Dec '17

20 Dec '17

We have a FAS3250 that's primarily backup storage. It hosts a lot of snapmirror targets, and a few mounted filesystems with backup data. As the hardware is getting old, we've purchased a shiny new FAS8200 with a couple of 8TB drive shelves. We assume that the FAS8200 can be initialized on 9.2 and above using the ADP on external drives feature, to partition those 8T disks, so we don't have to throw away about 50T of storage just on the root aggregates. However... the FAS3250 hardware can only run ontap 9.1. Newer versions of ontap are not available on that hardware. And to make the 8200 nodes join the existing cluster, it has to run the same sofware version (9.1), so... it cannot be initialized with ADP. And you can't initialize first and partition later, because repartitioning wipes all existing data. That's our dilemma. I've actually tried to "manually" partition the disks, by going into maintenance mode and using "disk partition" to force the 8200 nodes to see only partitioned disks, and then re-initializing them using boot menu "4 - clean config and reinitialize disks". That fails, and 9.1 doesn't want to write a root FS to partitioned disks (it does wipe them, though). Besides, it would likely be unsupported. I did learn some interesting things about the "disk partition" command, by the way, like the "-b" blocksize is in 4k blocks, and the '-i' option that numbers partitions starts at 1, which is a data partition, and number 2 is the root partition, at least in the 2-partition root/data setup. So we either have the option to throw away a large chunk of storage for root aggregates, initialize the new nodes on 9.1, join in cluster, and move the existing data using 'vol move' and all the cDOT goodness that comes with it. ... or build the new 8200 as a separate cluster, initialize it with 9.3, partition the disks via the boot menu, and then move the data over using snapmirror, and remounting the clients. That's doable because most of the data is snapmirror target anyway, and there's a limited number of mounted filesystems that would need a remount. It's a shame that cDOT doesn't have "snapmirror migrate" like 7mode did. Does anyone have any other options? All I could think is get swing gear and basically do the migration twice, first to hardware that supports ontap >= 9.2, then to our new 8200. But I'm not willing to spend a lot of money renting the swing gear and getting a lot of extra setup work basically because of a flaw in netapp software.

Re-cable existing shelf into new loop
by TAYLOR DANIEL 29 Nov '17

29 Nov '17

Hello, We need to re-cable a shelf out of its current loop into a new one, just interested to know if anyone had done this without issue? We want to do this non disruptively so keen to hear other peoples comments and thoughts on this and if possible without causing a panic. Running 9.1P8. Thanks Dan

3.5" 15KRPM -vs- 2.5" 10KRPM SAS
by John Adams 27 Nov '17

27 Nov '17

Hello, I have AGGRs made out of 3.5" 15KRPM SAS drives. One of these drives failed, and NetApp sent a 2.5" 10KRPM SAS drive in a 3.5 sled as replacement. After asking about this, they said: After investigating, the following were my findings: "As part of the NetApp qualification process, there is no performance degradation with the qualified X90-412B-R6 / SP-412B-R6 10K RPM drive as the seek distances are reduced to be equal to a full stroke 15K RPM drive." As for the physical size difference: "The only difference is that the 412A is a 3.5 inch HDD while the 412B is a 2.5 inch HDD. The difference in size is negated by a bracket within the carrier assembly in the 412B. So while the two HDD’s look different, the 412B is fully compatible with the 412A." So what's your take on this? The "don't mix 10K and 15K drives in the same aggr" keeps ringing away in my head. Thanks for your thoughts.

I think it’s time for a lab experiment with hybrid aggregates of different speeds. Maybe there’s a way to mix in some 7.2k drives for fun. .

But really, mixing is a BEST practice not-to-do, but when you explore the practicability of doing so, it's not so bad, and the differences exist only on paper* when you do whats said here, 2.5" in a 3.5" aggr. Its a lot of fun math, but sector density per RPM...etc...10k is the "same" as 15k. Smaller disk, shorter seeks (butterfly worst case)....there's really no argument that supports that this is a bad idea anymore. Because the best-practice back when, was when everything was equal. It no longer is..so it doesnt matter in the context of the old maths anymore.

cluster mode quota management?
by Sami Kapanen 22 Nov '17

22 Nov '17

Hi, What tools do you use for user quota management with clustered ontap? With 7mode we used the System Manager GUI, but now cmode 9.0P1 there is bug that won't list all users in GUI.. and that has been open for a long time now, apparently our case is the only one :/ Sk

FAS2240-2
by Sally Rogers 16 Nov '17

16 Nov '17

I have an FAS2240-2 that is out of maintenance. I'd like to buy some shelves off eBay and add them to it but I'm not sure if the number of shelves/disks is limited by the license codes. Does anybody know if there is any such restriction besides the 144 disk limitation? Thanks, Sal

NDMP to tape, cDOT 8.3, command line?
by John Stoffel 09 Nov '17

09 Nov '17

Guys, I need to write one damn volume to tape on a cDOT 8.3.2p9 four node cluster. LTO5 drives hooked up with FC. I can setup NDMP in VServer mode and get that part working. But I can't find the tool to start a dump to tape of the volume. ndmpcopy just does filer to filer copies. You can't use 'dump' any more from the console, it's all NDMP based now. I guess I'll have to just configure Netbackup 7.7.3 with NDMP to make this happen, but then I'll need to figure out how to backup a specific snapshot. Such a pain... John

Ontap 8.2.5 FAS8020 SP firmware 3.0.4
by Douglas Siggins 08 Nov '17

08 Nov '17

Greetings, Has anybody upgraded to Ontap 7mode 8.2.5 on FAS8020? I do have a case in, but as you can imagine it is moving slowly. I dont yet feel the need to start screaming. The Ontap update is autoupdating the SP to 3.0.4, and causing some issues: sp.device.fw.mismatch:warning]: Device firmware version mismatch detected: eth_switch:Rev:2,Img:3-mismatch Couple of oddities with this: There isn't a 3.0.4 SP firmware available via netapp website nor is it documented in the SP matrix https://mysupport.netapp.com/NOW/cgi-bin/fw?platform=FAS8020&type=sp_ontap&… https://mysupport.netapp.com/NOW/download/tools/serviceimage/support/Servic… I've gone into debug mode and issued SP netapp01*> sp switch-update Which seems to have worked, but the new error then becomes: sp.device.fw.mismatch:warning]: Device firmware version mismatch detected: 12:Rev:fan,Img:-mismatch So I presume I should run: SP netapp01*> system fan update Warning: system sensors monitor and system sensors thermal-mgmt should be disabled both on this controller and partner controller (if installed). Continue? [y/n] At which point I thought it best to figure out exactly what is going on here. I think the following message might be related. monitor.temp.unreadable:info]: The controller temperature (CPU0 Temp Margin) is not readable. Regards, Douglas
