NDO & CIFS
by Milazzo Giacomo 29 Jul '15

29 Jul '15

Hi all, with cDOT is there a way to avoid that CIFS sessions fall during a takeover? In 7 Mode when an NDU operation is performed CIFS must is interrupted and open CIFS sessions fall if not closed before. Is there a way using failover groups of the data LIF to avoid this? Regards,

Deleted Performance Manager
by Carl Howell 28 Jul '15

28 Jul '15

How can I remove a cluster from a deleted installation of Performance Manager so that I can add it to a new instance of Performance Manager? When I attempt to add the cluster to the new Performance Manager, it tells me that it has to be removed from the deleted installation first. Thanks, --Carl

Hot Shelf Removal - check for mailbox disks first before remove ownership
by Gelb, Scott 24 Jul '15

24 Jul '15

The hot shelf removal feature is great, but the documentation at https://library.netapp.com/ecmdocs/ECMP1367947/html/GUID-2B80FBD2-007D-4D19… is missing a check. An edge case if you had mroot on those disks prior, and then moved mroot to other disks/shelves for the hot removal. If the disks on the shelf or shelves have mailbox disks, right after you remove ownership from the disks (even though all zeroed spares), the node will crash. The ha-partner will not be able to takeover. Then the ha partner will also crash with an inconsistent mailbox. We had both nodes drop after removing ownership from a shelf that was being removed. It is an easy fix to get to maintenance mode and mailbox destroy local, but add that to your run book for hot shelf removal. We didn't have any data on the ha-pair for the maintenance (the great thing about cDOT which averted any outage even during this maintenance). We recovered after reassigning the disks and deleting the mailbox (had to do that twice) then both nodes came back up after coredump and mailbox was recreated and storage failover was able to enable again. ::> set adv ::*> stor failover mailbox-disk show One other note on the move mroot procedure https://kb.netapp.com/support/index?page=content&id=3013873&locale=en_US The article now lists to turn on nvfail (submitted that update a while ago), but some systems also had create_ucode enabled on vol0, so I check "vol options vol0" prior to move, then match the settings after the move in addition to nvfail. Also, if you have cdpd.enable on and ip.fastpath.enable off, both of those need to be reset since mroot move sets them back to cdpd off and fastpath on defaults (8.3P1).

Cluster evolution
by Milazzo Giacomo 22 Jul '15

22 Jul '15

Hi everybody, suppose that for technical (i.e. a 3240HA controller pair that does not fit with a 8060HA one in the same cluster) reason I've to start with two different 2 nodes cluster, each of the two managing its respective aggregates and node. So I can have now: CLUSTER1-01 and CLUSTER1-02 (3240HA) and CLUSTER2-01 and CLUSTER2-02 (8060HA) In the future customer could have budget to do a tech refresh on the first cluster changing the heads to an 8000 pairs. Well, what's about the merge of the CLUSTER1 nodes to the CLUSTER2 preserving all data in CLUSTER1 aggregates? So I mean that I would have in the end a 4 nodes cluster and not two separate 2 nodes ones. Is there some procedure? Regards.

FAS-2554 cDOT sanity check requested
by Roy McMorran 22 Jul '15

22 Jul '15

Hi all, We recently purchased a NetApp FAS-2554 and I'm getting what I feel is less than stellar performance. I have a case open with support. But I'm trying to 'calibrate my expectations' a bit, so I thought I'd send this out to the list. Any feedback would be appreciated. Here's a some info about the configuration cDOT, 8.3.1RC1 2-node switchless cluster 22 SATA drives (3TB) in two RAID-DP aggregates + 2 spares 22 10K SAS drives (900GB) in two RAID-DP aggregates + 2 spares No flash (yet?) 10Gb cluster interconnect 10Gb to server(s) with jumbo frames 2 vFilers - the one under test has a volume on the sas_data_1 aggregate which is serving NFS v3 (TCP) I'm currently testing with a Cisco UCS C220 M4S running CentOS 6.6 as the NFS client. We noticed that performance (on a database load) seemed poor, so I started some benchmark testing with "iozone". The test I'm looking at in particular is sequential writes with an 8K record size. The write throughput was 2MB/S! There are no other workloads on the filer or the server. NetApp suggested a workaround for the bug described here: http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=876563 and that actually improved things - my sequential write throughput test can now do 15MB/S. Definitely better, but that still seems slow to me. So with all that background here is my question - does anyone have a similar configuration out there, and what sort of write speeds are you seeing? I'm just looking for a sanity check. Is 15MB/S reasonable? Thanks! Roy McMorran

Latency Counters - Perfmon versus Resource Monitor
by Philbert Rupkins 21 Jul '15

21 Jul '15

Hello Toasters, I have a situation in which Resource Monitor shows 100 - 400 ms disk Response Time (latency) for various processes in the Disk-Disk Activity tab. Resource Monitor doesnt break Response Time down into read/write/other so I hopped over to perfmon. I enabled the following perfmon metrics for the block device showing 100 - 400ms response time in Resource Monitor: Physical Disk: Avg. Disk Bytes/Read Avg. Disk Bytes/Write Avg. Disk Bytes/Transfer Physical Disk: Avg. Disk sec/Read Avg. Disk sec/Write Avg. Disk Sec/Transfer Those permon counters were chosen to have a look at block size and latency. Perfmon reported very large values for Avg. Disk Bytes/Read (up to 500,000) which may explain some of the higher Response Time numbers in Resource Monitor. HOWEVER, perfmon showed very low numbers for Avg. Disk sec/Read whereas Resource Monitor showed 100 - 400 ms. Does anybody know what might account for the difference in Response Times between perfmon and Resource Monitor? Specifically, the difference between Avg. Disk sec/Transfer (perfmon) and the Response Time column in Resource Monitor? Windows Server 2008, Exchange 2010, NetApp v3250 running 8.1.4P3 7-Mode. All LUNS presented via iSCSI. -Phil
