Administrivia: twenty years old today
by Tom Yates 21 Feb '17

21 Feb '17

I apologise for adding to everyone's mailbox, but I noticed that this list is twenty years old today - on 21/2/1997 I initialised the list, which was then hosted at Mathworks, and run by majordomo. The 20th anniversary of the first post (which wasn't mine!) will be 5/3/2017 (that is, in about two weeks), but I won't be saying all this again. Many thanks to everyone who has shared so generously of their time and expertise over the years, helping other people on this list, and to Mathworks, who hosted it for most of the last two decades. Bonus thanks to Kendall Libby, who has co-moderated this list with me since the move to teaparty.net (and mailman). -- Tom Yates - http://www.teaparty.net

NFSv3 mount on NTFS volume on cDOT 9.0 - UID getting mapped to 65534
by Ray Van Dolson 20 Feb '17

20 Feb '17

Have an NTFS volume being shared out via NFSV3. SVM is part of AD and NIS. When an NIS-joined client lists directories under the export, everything seems to be mapped to UID 65534. I'm able to validate this: ::*> vserver security file-directory show -vserver file_ntfs -path /setup-staging/raytest_windows Vserver: file_ntfs File Path: /setup-staging/raytest_windows File Inode Number: 1317151 Security Style: ntfs Effective Style: ntfs DOS Attributes: 10 DOS Attributes in Text: ----D--- Expanded Dos Attributes: - UNIX User Id: 65534 UNIX Group Id: 65534 UNIX Mode Bits: 777 UNIX Mode Bits in Text: rwxrwxrwx ACLs: NTFS Security Descriptor Control:0x8004 Owner:DOMAIN\rvandolson Group:DOMAIN\Domain Users DACL - ACEs ALLOW-Everyone-0x1f01ff-(Inherited) ALLOW-Everyone-0x10000000-OI|CI|IO (Inherited) However, the following makes me think the filer knows how to map AD usernames to Unix (NIS) usernames just fine: ::*> diag secd name-mapping show -vserver file_ntfs -direction win-unix -name DOMAIN\rvandolson -node red-str-napcl-p03-02 ATTENTION: Mapping of Data ONTAP "admin" users to UNIX user "root" is enabled, but the following information does not reflect this mapping. 'DOMAIN\rvandolson' maps to 'rvandolson' ::*> diag secd authentication translate -node red-str-napcl-p03-02 -vserver file_ntfs -unix-user-name rvandolson 580345 I don't have a default-win-user set: ::*> vserver nfs show -vserver file_ntfs -fields default-win-user vserver default-win-user --------- ---------------- file_ntfs (but I think the default is 65534). Shouldn't cDOT be returning 580345 for the UNIX User Id rather than 65534? Seems to be the case on 7-mode... Thanks! Ray

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? Running OnTap version is: NetApp Release 8.2.3P4 7-Mode: Fri May 29 14:06:54 PDT 2015 Best, Alexander Griesser Head of Systems Operations ANEXIA Internetdienstleistungs GmbH E-Mail: AGriesser(a)anexia-it.com<mailto:AGriesser@anexia-it.com> Web: http://www.anexia-it.com<http://www.anexia-it.com/> Anschrift Hauptsitz Klagenfurt: Feldkirchnerstraße 140, 9020 Klagenfurt Geschäftsführer: Alexander Windbichler Firmenbuch: FN 289918a | Gerichtsstand: Klagenfurt | UID-Nummer: AT U63216601

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
