CPU usage and HA
by Martin 08 Apr '14

08 Apr '14

I know that if a Filer is not busy serving data it will run background task at a higher priority that will use the spare CPU while the Filer is not under load. In an active/active config the Filer CPU shouldn't be over 50% on each controller as above this the Filer is not longer HA. My question is if a Filer is showing low latency and isn't busy but its CPU is at 50% on each controller is this an issue? I'm not clear if you have two controllers showing 40/50% CPU due to background tasks that isn't busy whether it will still be HA if one controller were to fail? My thinking is those background tasks will just run at a lower level (some may not run in failover state??) -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/CPU-usage-and-HA-tp25… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

stats list instances disk output format
by Jordan Slingerland 07 Apr '14

07 Apr '14

Why does "stats list instances disk" show the disk instance name as what looks like hex but so far I have not been able to translate to anything meaningful. Example: 5000CCA0:0F91CAAC:00000000:00000000:00000000:00000000:00000000:00000000:00000000:00000000 Can anyone tell me how an easy way to map this to the disk name format I have grown to know and love. --Jordan For the seventh consecutive year, Independent Health was named one of the best companies to work for in New York State.

LACP oddness

Later, a packet arrives and the netapp ups the leg of the portchannel. Does anybody with a deep understanding of this know why we get these messages and why it appears the netapp is uping and downing the interface and if this is serious. Any help appreciated.

FAS3240c SAS Cabling Question
by Carl Howell 04 Apr '14

04 Apr '14

I have a FAS3240c that has been running for years. I noticed today, while putting in some new shelves, that the IOM modules in the last shelf of a stack of DS4243's are both cabled to the wrong nodes. Filer1 SAS port 3a goes to the circle port on IOM B instead of IOM A and visa versa. Do I have to take the entire cluster down to fix this? Thanks, --Carl

simulator 8.2 doesn't appear to be running NFS?
by Rue, Randy 28 Mar '14

28 Mar '14

Hello Again All, Trying to set up an 8.2 simulator to test the nfs.authsys.extended_groups_ns.enable option (more on that in yesterday's thread). Got it running in VMware player, can reach it from the real network, can manage it in OnCommand. Added the volume, qtree, export, etc >From the CLI "exportfs" shows the export as available with access to the specified netgroup. From the GUI the export is visible and the netgroup enumerates to its members. Added the simulator license for the correct serial number and the NFS stack is licensed (although its "State" is "-NA-" on the license page). But if I try to "showmount -e" the filer from any client (CentOS or Solaris) I get "mount clntudp_create: RPC: Program not registered" as if NFS wasn't actually running. If I run "rpcinfo -p" against the filer I get a long list of ports but nothing related to mountd. "options nfs" from the CLI shows v2 and v3 enabled. What did I miss? Thanks in advance... Randy in Seattle

DOT 8.1 disk in a DOT 7.3 filer
by R M 27 Mar '14

27 Mar '14

Gents, My Google-fu is exhausted. I am trying to use disks from an 8.1.3 system in a 7.3.7 filer. I am aware of the disk label problem and I have tried the half-dozen step process (documented in several places) for re-labeling the drives. I'm not able to wipe the label from the drives due to the following: *> label wipe 0a.17Error: label wipe not permitted as the disk has a bad RAID version. *>label makespare 0a.17*********************************************************Label editing is highly dangerous and should be attemptedONLY by NetApp Customer Support Engineers.Misuse can cause ALL data to be permanently lost.*********************************************************'Label save': Error while trying to save Label 1 on disk 0a.17: error 15. I get this in both diag mode and when booted into maintenance mode. Any ideas? RM

High CPU usage after upgrade to 8.1.4
by Marcus Nilsson 27 Mar '14

27 Mar '14

Hi, I have a FAS3160 7-mode system where CPU usage has increased by around 5x over all cores since after upgrade from 8.0.3P3 to 8.1.4P1. NetApp support is claiming the increase is due to different multicore behavior, but I find that a little hard to believe since the increase it happening on all cores and on both nodes in the HA pair. We have since the upgrade noticed longer running dedupe jobs and more sluggish ssh prompt.

CDOT 8.2p5, NFS w/ Win2012 or Win 7?
by Michael Garrison 26 Mar '14

26 Mar '14

We recently migrated a bunch of NFS volumes from 7mode to a cdot system. The CDot cluster has only NFSv3 enabled. We have some Windows 7 and Windows 2012 machines that can no longer mount the NFS volumes. No matter how they try it, they receive the following error: C:\Windows\system32>mount -o nolock \\server\share Z: > Network Error - 53 > Type 'NET HELPMSG 53' for more information. Yet, the exact same mount parameters work fine on the 7mode share. They've rebooted, tried multiple computers, and it's consistent behavior. Is anyone else out there running CDot 8.2p5 and have any success with Win7 or Win2012 machines? Thanks, Mike Garrison University of Michigan

Re: NFS Datastore Disconnect
by Philbert Rupkins 18 Mar '14

18 Mar '14

Thanks for the response! Yes. We are running 10g. I know flow control is enabled on the 10g adapters on the NetApps. Not sure if it is enabled on the switches. I'll have to check with our networking team. Do you know if a pause frame would show up somewhere in the port statistics? The switches are Nexus 5K's. We have been examining TCP Window Sizes during packet traces but have not found anything interesting. Of course, whenever we run a packet capture the problem never occurs so TCP Window Sizes could still be an issue.

NFS Datastore Disconnect
by Philbert Rupkins 18 Mar '14

18 Mar '14

Hello Toasters, Anybody have any issues with seemingly random ESXi 5.5 NFS datastore disconnects during heavy load? Our Environment: ESXi 5.5 F3240 ONTAP 8.1.2P4 It doesn't happen all the time. Only during heavy load but even then there is no guarantee that it will happen. We have yet to find a consistent trigger. Datastores are mounted via shortname. We are planning to mount via IP address to rule out any name resolution issues but that will take some time. DNS is generally solid so we are doubtful DNS has anything to do with it but we should align ourselves with best practices. We serve all of our NFS through vfilers. Some of our vfilers host 5 NFS datastores from a single IP address. I mention this because I have come across documentation recommending a 1:1 ratio of datastores to IP addresses. vmkernel.log just shows that the connection was lost to the NFS server. It recovers w/in 10 seconds. We have 11 nodes in this particular ESX cluster. Not all 11 ESXi nodes lose connectivity to the datastore at the same time. I've seen it affect just one ESXi node's connectivity to a single datastore. I've also seen it affect more than one ESXi node and multiple datastores on the same filer. Until recently, it was only observed during storage vmotions. We recently discovered it happening during vmotion activity managed by DRS after a node was brought out of maintenance mode. As I said before, it is generally a rare occurrence so it is difficult to trigger on our own. Thanks in advance for any insight/experiences. Phil

7-mode console unresponsive
by Mark Flint 13 Mar '14

13 Mar '14

Hi all, I have a 7.3.3 3170 HA pair, out of maintenance now, that’s become unresponsive to the console. It accepts the login/passwd and then nothing. No prompt, although it does appear to be echoing the log as it happens. Unit is experiencing high load, and I can’t get into it to find out why. Has anyone seen this before, and what was the fix fior it, if any? I know i can fail it over and reboot it, but I’d rather know what and why before I do so, as my mgmt team will want some form of answer that isn’t ‘meh’ with a shrug :( Thanks, Mark Flint mf1(a)sanger.ac.uk -- The Wellcome Trust Sanger Institute is operated by Genome Research Limited, a charity registered in England with number 1021457 and a company registered in England with number 2742969, whose registered office is 215 Euston Road, London, NW1 2BE.

Snapmanager Exchange - Archived Backups with OnCommand (DFM)
by Roth, Jürgen 12 Mar '14

12 Mar '14

Hello, my Name is Juergen Roth and I´m a Systemadministrator for Windows Server and Netapp Filers. We have two FAS3040 as a HA-Cluster. On the „primary“ we have a qtree with a Exchange LUN. This LUN is a RDM for the one Exchange Server. We use Snapmanager Exchange for Backup the Public Folder and Mailbox Database (only one Databse). We take the OnCommand Server for a Data Protection Job and archive the Snapshots from the „primary“ to the „secondary“ filer in a extra volume only for the Data Protection Job. Another Server hast he Snapmanager Exchange with SingleMailboxRecovery (SMBR) for doing restores. On all Servers we have the same Versions of SnapDrive and Snapmanager Exchnage. Now the Problem: The Snapshot Backups on the „primary“ filer can directly opened with SMBR. The archived Backups On the „secondary“ filer can not opened directly. Following error message comes: [cid:image001.png@01CF379C.6B1DBA90] We can manual mount the Snapshot in SnapDrive and then we can starting SMBR for using this Mount. But thats not the way, because our IT Service should do restores.

Flash Pools, without the Flash?
by John Stoffel 11 Mar '14

11 Mar '14

So I got a price quote on Netapp's Flash drives that you stick into a Flash Pool and having my eyebrows rise off my forehead. Of course Netapp's prices are/were no worse than EMC's prices for single SSD drives, etc. Basically crazy expensive in both cases. Now I'm entertaining the silly idea of just using a mix of SAS and SATA drives in a flash pool instead. Get *some* of the advantages, but lots cheaper pricing. Esp using those big fat slow 4Tb drives in the dual drive sleds. Front them with a bunch of SAS disks and it should do quite nicely. God knows there shouldn't be any technical reason this can't work, it's just a matter of moving blocks from one raidgroup in an aggregate to another. But the Netapp technical sales guy was surprised by the suggestion. I'm loving the transition of SSDs into the enterprise space, because it's forcing all kinds of changes on the vendors that are long overdue. Just putting a pair of mirrored SSDs into a server is a big boost. Using it to cache is good too. What do others think? John

Orphaned volume entries in c-mode VLDB
by Mike Thompson 28 Feb '14

28 Feb '14

Hey all, We had a number of volume creates happen on our 8.0.3 (admittedly ancient, but not upgraded due to lack of support) c-mode cluster, during a period of excessive load, when the target filer/aggregate was having some sort of problem. This led to the following type of entries in syslog: Feb 27 19:06:34 filer2a mgwd: mgmtgwd.jobmgr.jobcomplete.failure: Job "Vol Create" [id 208390] (Create v181771) completed unsuccessfully: Failed to create the volume on node. Reason: Node is not healthy. This may leave the volume record in the Volume Location Database. (1). Whatever problem this node was having at the time corrected itself shortly thereafter. This appears to have not created the actual volume on disk, but has also indeed left an orphaned record of that volume in the VLDB. If I do a 'vol show -volume v181771' it comes back with: Virtual Server Name: dd Volume Name: v181771 Aggregate Name: near3a2 Volume Size: - Volume Data Set ID: 22798575 Volume Master Data Set ID: 2170062839 Volume State: - Volume Type: - Volume Style: flex Volume Ownership: cluster Export Policy: default User ID: - Group ID: - Security Style: - Unix Permissions: - Junction Path: - Junction Path Source: - Junction Active: - Parent Volume: - Comment: Available Size: - Total Size: - Used Size: - Used Percentage: - Total Files (for user-visible data): - Files Used (for user-visible data): - Space Guarantee Style: - Space Guarantee In Effect: - Percent of Space Reserved for Snapshots: - Used Percent of Snapshot Reserve: - Snapshot Policy: daily Creation Time: - Anti-Virus On-Access Policy: - Inconsistency in the file system: - But if I do a 'node run local vol status v181771' on the node that houses the aggregate in question, it says no volume exists. 'set diag; volume lost-found show' doesn't return any results either. So it would appear we do indeed have a number of bogus volume entries in the VLDB. Doing a 'vol delete v181771' yields: ERROR: command failed on entry "dd v181771": Unable to lookup volume attributes for volume v181771. Reason: success Question is, is there a sane/safe way to clear these out of the VLDB? Thanks for any help!

We have two systems and their flexscale output is given below. System with the low hit percentage is a very busy system with Network shares, Exchange 2010 and VMware on it. I am seeing very low hit percentage for flexcache and want to know if this should be a concern.

Re: OSSV / SnapVault Newbie - Scheduling an automatic update.
by Ray Van Dolson 19 Feb '14

Thanks. I actually ended up running: dest> snapvault snap sched -x napc2_p2_EFT1 eft_sched 1@mon-sun@0,6,12,18 Am I correct in assuming that the "sv_hourly" name isn't significant? I couldn't find any indication in the man pages that it was, but may have missed something. I now have the following snaps: dest> snap list napc2_p2_EFT1 Volume napc2_p2_EFT1 working... %/used %/total date name ---------- ---------- ------------ -------- 0% ( 0%) 0% ( 0%) Feb 04 13:03 eft_sched.0 1% ( 1%) 0% ( 0%) Feb 04 12:49 red-str-napc2-p2(1574798766)_napc2_p2_EFT1-base.0 (busy,snapvault) 25% (25%) 9% ( 9%) Feb 02 08:34 schedule_02022014_074939.0 The "schedule_02022014_074939.0" may be one I attempted to schedule from System Manager and then removed. Presumably this snapshot is safe to delete. My intent is to ultimately convert this volume/qtree into writeable mode via NetApp KB 1010906. I haven't tried this with anything but the "base" snapshot present. I'm hopeful this won't cause any issues or confusion, but guess I can give it a test run.

free_space_realloc setting in 8.1.x (8.1.4)
by Michael Bergman 11 Feb '14

11 Feb '14

Ok so I'm stumped. What more's needed to set this as intended? Anybody knows? (Yes, I know what it's doing, or rather what is isn't doing and what a potential effect of that might be for our particular scenario.) Don't tell me there's another secret priv level I've never heard of...! $ ssh -ax filer filer> useradmin user list xxxxxx Name: xxxxxx Info: Michael Bergman Rid: 123456 Groups: Administrators Full Name: Allowed Capabilities: login-*,cli-*,api-*,security-* Password min/max age in days: 0/4294967295 Status: enabled filer> priv set diag Warning: These diagnostic commands are for use by NetApp personnel only. filer*> priv diag filer*> aggr options aggr0 free_space_realloc no_redirect aggr options: no_redirect not allowed in admin or advanced mode filer*> /M

Verify SME snaps -- yea or nay?
by Andrew Laurence 11 Feb '14

11 Feb '14

For those running Snap Manager for Exchange... do you verify the snapshots? We've been running Exchange on filer iSCSI luns for several years, dutifully verifying our snapshots and dealing with the added IO during verifies. We're currently in process of setting up mirrors to a remote filer, with the intent of running the verifies on the remote filer. I heard in conversation, however, that verifies have fallen out of fashion. Is it that the snap process has so little error that there's no point in running verifies? Are verifies obviated when running in a DAG? Thanks for your thoughts,
