Running Cassandra on FAS
by Kalra, Manish 20 Feb '17

20 Feb '17

Does anyone has experience running Cassandra DB on Netapp All Flash Array. We are planning to deploy cassandra on Netapp AFF but everywhere I see online they discourage running Cassandra on shared storage. Any good/bad experiences you would like to share? Manish

Fwd: cDOT 9.1 , Netapp Volume encryption (NVE) and an external key management server.
by jordan slingerland 16 Feb '17

16 Feb '17

Based on this slide from the netapp university and the following doc, it looks to me like NVE is OKM only. Anyone have any information to support otherwise? https://library.netapp.com/ecm/ecm_download_file/ECMLP2572742 (my screenshot of university slide was blocked due to size) https://netapp.sabacloud.com/Saba/Web_spf/NA1PRD0047/common/leclassdetail/ regdw000000003193830 On one of the slides here in the 9.1 new features document it says "Federal Internet processing standards 140...level 2 compliance, NSE systems and external KMIP server still required) I take that to have the unfortunate meaning that NVE cannot be used with an external key management server. --Jordan

compute-reclaimable failing
by Ehrenwald, Ian 16 Feb '17

16 Feb '17

Hello Has anyone else run into an issue where a compute-reclaimable on a snapshot times out or fails after about 4 minutes of execution? I've tried this multiple times with the same result each execution. My-Cluster1::> volume snapshot compute-reclaimable -vserver MY_SVM -volume LARGE_FLEXVOL -snapshots SOME_BIG_OLD_SNAP Error: command failed: Cannot determine the status of Snapshot copy reclaimable operation on volume "LARGE_FLEXVOL" on Vserver "MY_SVM". If necessary, try the operation again. My-Cluster1::> The node the operation is running on is pretty hot in terms of CPU and disk and the volume the snapshot is part of is large (18t) and busy too in terms of IOPS, anywhere from 8K to 18K throughout the day. Am I hitting some sort of internal timeout for calculation? -- Ian Ehrenwald Senior Infrastructure Engineer Hachette Book Group, Inc. 1.617.263.1948 / ian.ehrenwald(a)hbgusa.com This may contain confidential material.

cDOT 9.1 , Netapp Volume encryption (NVE) and an external key management server.
by jordan slingerland 15 Feb '17

15 Feb '17

I am just beginning to research a possible deployment of a new 9.1 system hoping to utilize NVE with an external key management server. It turns out the Onboard Key Manager does not appear to be FIPS compliant. I am not very far down this rabbit hole yet, but the documents I am reading so far only mention the Onboard Key Manager for use with NVE in 9.1 Could anyone (a) confirm the NVE feature is able to work with an external key management server and (b) recommend any that i might research. Thanks, Jordan

CDOT change SNMP traphost port?
by BERNTSEN Basil 14 Feb '17

14 Feb '17

Hi folks, Does anyone know whether it's possible to set CDOT 8.2.3 up to send SNMP traps to a traphost using a specific port number? I tried system snmp traphost add xxx.xxx.xxx.xxx:xxxx and it didn't work. I googled around a bit on this subject and couldn't find any results either. Thanks!

Broken file on CIFS Share
by Alexander Griesser 13 Feb '17

13 Feb '17

Hey there, I've never seen something like this before, so maybe someone can help me with that. I do have a file on a CIFS share which can be deleted on a windows client accessing this file, but it immediately reappears after you hit F5 in the explorer window. On the filer itself (7-mode installation), I can also see this file: netapp02*> ls "/vol/CIFS_SHARES/some/folder/structure" . .. file01.jpg I've mounted this share on a linux system and there it looks like this: # ls -l ls: Access to file01.jpg not possible: File or directory does not exist total 0 -????????? ? ? ? ? ? file01.jpg I'm not sure where this is coming from and how to fix that - any ideas?

CIFS Migration - 7.3.7 to 8.3.2
by Stephen Stocke 08 Feb '17

08 Feb '17

Hello Fellow Admins Sorry for the long email. I'm planning a migration of CIFS data from a FAS2020 (7.3.7) to a FAS2552 (CDOT 8.3.2). I'd like to share my rough migration plan and see if anyone has advice/cautions/optimisations to share. In my case, I don't need to just migrate the share data, I also need to split the data on the single CIFS source volume to several volumes on two SVMs on the destination cluster. Luckily, I also have a 7-mode system running 8.2.4 (FAS2240-2) at my disposal. My rough plan is as follows: 1. Qtree-SM the various departmental subfolders from FAS2020:/vol/cifsvol/folder[1,2,3,..] to FAS2240:vFiler[1,2]:/vol/cifsvol[1,2,3,...]. These subfolders aren't Qt's but my understanding is that this is possible. 2. During a maintenance window, update the QSMs, break, create shares, re-point DFS folder targets, etc. 3. Upgrade vFiler volumes to 64-bit (I believe this happens automatically). 4. Use 7MTT or manual transition-SM relationships to sync the data from the FAS2240 to the cluster SVMs. 5. During a second maintenance window, update the SMs, break, re-point DFS folder targets, etc. 6. Cleanup the FAS2020 and send it to live on a farm somewhere. Of course, we could just setup the new SVMs & vols and use a tool like Robocopy to migrate the data but we feel more comfortable using storage level functions if possible. Does anyone have any thoughts on the above? I'm about to start running through this process with test data and I'm hoping your advice/experiences might help me on my way. Thanks in advance. Steve

Issue with CIFS shares and .temp files
by Mark Saunders 03 Feb '17

03 Feb '17

Hi I am the administrator of a c mode filer for one of my companies customers and the customers are having some issues with CIFS shares. This issue is that they are getting .temp files left in all folders of the share regardless of the application used which they think are creating a mess and are manually removing. Is there anything that can be checked or changed on the storage end to change this behavior or is it more likely to be an issue somewhere else ?

super secret flags
by Peter D. Gray 03 Feb '17

03 Feb '17

Hi people Just out of idle curiosity, am I the only netapp admin who does not know about the super secret flags to allow snapmirror to actually work at reasonable speed? We were running 8.3.2 cluster mode, and spent weeks looking into why our snapmirrors to our remote site ran so slowly. We were often 2 days behind over 40G networks. Obviously, we focussed on network issues. And we wasted a lot of time. We could make no sense of the problem at all since sometimes it appears to work ok, the later the transfers slowed to a crawl. We eventually opened a case and it did not take to long for a reply which basically said "why don't you just disable the global snapmirror throttle." I had already looked into such a beast, but found nothing. As you may or may not know, it turns out to be a per node setting. The name of the flag is repl_throttle_enable. Of course, you can only see such flags or change them on the node, in privileged mode. Setting the flag to 0 immediately (and I do mean immediately) allowed our snapmirrors to run at the speed you might expect over 40G. Instead of taking 2 days, snapmirror updates now took 2 hours. We have since upgraded to 9.1. The flags reverted to on, but again can be set to off. I think there is a documented global snapmirror throttle option in 9.1, but I have not looked into that yet. Are we the only site in the world to have seen this issue? We use snapmirror DR for all our mirrors which may be a factor. As I said, just idle curiousity and maybe helping someone avoid the time wasting we had.
