Couple of random questions
by Mark Saunders 04 Jul '17

04 Jul '17

Hi all just wondered if anyone can just answer a couple of questions for me. 1 - We are migrating from a number of 7-mode filers to c-mode clusters and the clusters have AFF and FAS HA pairs, management do not want to move someone who is on HDD now onto flash to then move them back to HDD when the disk shelfs are all sorted out. I have suggested using QOS limits while the volumes are on the flash storage but the storage architect has said that it won't work and the customer will see a performance improvement even with QOS on but can't really explain the why behind what he is saying. This has put the whole migration on hold is there any reason a 1000IOPS limit on flash would give better performance that a 1000IOPS limit on HDD the only thing I can see happen is if the requests go over 1000 they will be served up at the start of the second and then there would be a pause until the next second. 2 - Has anyone had been using compaction on HDD aggregates I am thinking we can enable this on our vault volumes but have no idea what the performance hit on the controller would be currently our vault is hanging off of a FAS2554 but this will probably be getting swapped out for a FAS8020 during the working in question 1 so would like to think about saving as much space as is possible.

FreeBSD on NetApp hardware
by Bert Kiers 29 Jun '17

29 Jun '17

Hi, We have some abandoned NetApp 6290 hardware, that was replaced by FAS8080, and I want to run FreeBSD on it. The original software, OnTap, is also based on FreeBSD. Somebody once told me that it is simple, something like "just change the kernel loader address". Does anyone have more information about this? It would be so cool to run ZFS and bhyve on them (just for fun, not for production). Meanwhile, I am going to try netboot FreeBSD/amd64 and see how far I get. TIA, -- Bert Kiers, suspected terrorist Love MS-Windows? Must be Stockholm syndrome.

bsdsocket.queueLimit.reached
by TAYLOR DANIEL 27 Jun '17

27 Jun '17

Hello, We have been receiving this alert below intermittently and from what i believe this only reared its head after an upgrade to 9.1, we are operating on a version (9.1P2) where this supposed bug is fixed and it causes no issues that I am aware. Does anyone had any dealings with this alert? or know how to find out more about the potential cause? We are not aware of any network misconfigurations in the environment, but when I run a 'network connections active show' I see his port being used by our ESXi hosts for NFS. This also is reported by the other node in the cluster too and also at a remote site by another cluster. The alerts are random and appear maybe once a day. Maybe nothing to worry about but any information or help much appreciated...... Filer: filer-a Time: Tue, Jun 27 13:19:38 2017 +0100 Severity: LOG_ERR Message: bsdsocket.queueLimit.reached: Number of connection requests for the socket bound to port 924 having the IP address * has reached the limit of 7 connections. The socket uses TCP protocol. This event has occurred 1 times since the last warning. Description: This message occurs when the number of connection requests for a socket reaches the maximum. These connection requests include partially completed connections and connections that are ready to be accepted. Action: Network misconfigurations can cause connectivity issues such as asymmetric routing, which causes loss of ACKs. Check the network for any such misconfigurations.

Migrate root volume to partitioned disks after wipeconfig
by Alexander Griesser 23 Jun '17

Hey there, I've got a FAS2554 here which I've pushed through wipeconfig recently and interestingly, both controllers show different layouts after this process. Node 1 show the following root aggregate: RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- tparity 0b.00.1P2 0b 0 1 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 dparity 0b.00.3P2 0b 0 3 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 parity 0b.00.5P2 0b 0 5 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 data 0a.00.6P2 0a 0 6 SA:A 0 FSAS 7200 55176/113000448 55184/113016832 data 0b.00.7P2 0b 0 7 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 data 0a.00.8P2 0a 0 8 SA:A 0 FSAS 7200 55176/113000448 55184/113016832 data 0b.00.9P2 0b 0 9 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 data 0a.00.10P2 0a 0 10 SA:A 0 FSAS 7200 55176/113000448 55184/113016832 data 0b.00.11P2 0b 0 11 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 data 0a.00.12P2 0a 0 12 SA:A 0 FSAS 7200 55176/113000448 55184/113016832 data 0b.00.13P2 0b 0 13 SA:B 0 FSAS 7200 55176/113000448 55184/113016832 Node 2 does not have partitioned disks for root: RAID Disk Device HA SHELF BAY CHAN Pool Type RPM Used (MB/blks) Phys (MB/blks) --------- ------ ------------- ---- ---- ---- ----- -------------- -------------- dparity 0a.00.0 0a 0 0 SA:B 0 FSAS 7200 5614621/11498743808 5625872/11521787400 parity 0a.00.2 0a 0 2 SA:B 0 FSAS 7200 5614621/11498743808 5625872/11521787400 data 0a.00.4 0a 0 4 SA:B 0 FSAS 7200 5614621/11498743808 5625872/11521787400 Also, Node1 has raid_tec on the root aggregate, but that's OK I guess. So what I'd like to do now is to migrate the root aggregate on node2 to an aggregate with partitioned disks too, of course, but I cannot find any information on how to do that. I've tried to manually create an aggregate on node 2 and have manually assigned the root partitions to it, but it's always telling me that the disks are not owned by node 2 or the new migrate-root command just does not seem to support partitioned disks. Trying to avoid another wipeconfig here, since that will take ages again for zeroing all the disks... There's no data on the filer as of yet, so we're good to try with whatever someone can come up with :) Thanks, 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

Re: Metrics collection/reporting

Thanks Phillip! I did see this last week. It seems with the combining of OCUM and OCPM into one server the upgrade process might be a bit time consuming so I have it on the list to do once I read up on the process. Also, don't want to lose the feed from OCPM to NetApp Harvest and haven't verified that ability still exists in the new version. But yes, after reading the release notes I am anxious to see what this new combined server/interface looks like and test the functionality it provides. Q: Is the automation store going to live on? If so, will NetApp start providing new reports for OCUM/PM? The user community doesn't appear to be that lively.

Hi, I was recently tasked with presenting latency numbers for aggrs and vols on a regular basis. These would be numbers averaged over 30 days. We're on cDOT 9.1P2 and OCUM is, to say the least, anemic when it comes to reporting on such things.

Great question, and I don't know. :-) This is a request from our Architecture team. Quote: - Quarterly - 30 Days avg latency reports - Aggrs, total size, used size space free. - Aggrs, top 5 by latency - In those aggrs, top 5 volumes by latency. - Snapshots – volumes with snaps older than 4 weeks - Snapmirrors in lag longer than 48 hours. - Any outstanding issues with backups - Anything else they want to bring up, performance, scalability or operational concerns.

To clarify, yes, I can pull Graphite graphs into, say, SharePoint and am considering this route for some things. In fact, recent help I received from the Harvest author allowed me to create a graphical representation of inode usage in some volumes we have that are heavy inode eaters. This is a perfect case where Harvest/Graphite is very useful for reporting purposes. On Jun 12, 2017, at 10:27 AM, "s.eno" <s.eno(a)me.com> wrote: Thanks! And agreed!

AltaVault
by Chris Hague 06 Jun '17

06 Jun '17

Hi Toasters, We are looking at how AltaVault may help with our Backup environment and assist in a move towards a tapeless solution. We are not 100% NetApp so can't just rely on SnapVault as I would have in the past. One biggie would be our SQL maint plan's dump out .bak files to a share presented from AV.. But is it true WORM or are these files at risk of being deleted by human error? Appreciate Thoughts? Experiences? Gotchyas? On the AV technology as a whole. Many Thanks in advance, Chris.
