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

RE: Flash Cache

Sorry, I just realized I wasn’t specific enough (not enough coffee yet this morning). I’m specifically thinking about the 3220 and 3250. You can’t use the cards that worked in the 3210 and 3240 in them.

Supressing certain DFM alerts
by James Andrewartha 04 Mar '14

04 Mar '14

Hi, In Operations Manger (OnCommand UM 5.2) I have an alarm set to email me on all error or worse events. This works fine, however I have an OSSV host at the end of a lossy satellite link that sends me host/host agent down emails all the time. Is there a way to suppress DFM alerts for a particular host? Thanks, -- James Andrewartha Network & Projects Engineer Christ Church Grammar School Claremont, Western Australia Ph. (08) 9442 1757 Mob. 0424 160 877

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!
