snapvault memory allocation error
by Rhodes, Richard L. 22 Sep '14

22 Sep '14

Hi Everyone, Over the weekend we had a snapvault backup fail with memory allocation errors on the snapvault destination. This error occurred twice on the same volume, then hasn't come back. Can not allocate memory. (memory limit reached) (Cannot allocate memory) I run snapmirror and snapvault on all our volumes, but do it one operation at a time - NO concurrent snapvault or snapmirror operations. I search NOW and didn't come up with anything. This occurred on this particular volume … [View More]twice in a row (6 hours apart - backups run every 6hours), not on any other volumes. This volume is 410GB with 900k inodes - not even close to our biggest volumes. So this error is not related to size (capacity or num inodes), but seems specific to this volume.

Single-file Snaprestore Causing Performance Impact?
by Ray Van Dolson 19 Sep '14

19 Sep '14

Hi all; Running 8.1.2P4 in 7-Mode on an IBM N6240. We initiated a couple of single-file snaprestores which ran for 15+ hours on some busy SATA-based aggregates). During that time, we experienced intermittent issues connecting to the NFS services on this filer. Issues would clear up after a while (minutes or tens of minutes) and then return an hour or so later. We killed the snaprestores during one of the outages and observed a full recovery of the NFS service. It may have been … [View More]

Monitoring NDMP
by Andrew Laurence 16 Sep '14

16 Sep '14

Hi all, Am I crazy, or do NDMP loads not show up in Balance and OnCommand System Manager? I see that it's in the SNMP MIB, but is that really the only way to externally monitor service loads from NDMP? Thanks, Andrew -- Andrew Laurence Office of Information Technology atlauren(a)uci.edu University of California, Irvine

ndmpcopy from netapp to oracle zs3?
by Jordan Slingerland 05 Sep '14

05 Sep '14

I am trying to do an ndmpcopy from a 7m 8.1.4P1 to an Oracle ZS3. I am not even sure if this is possible, but It authenticates successfully then dies with a network communication error. Looking at a pkkt capture, the green is the netapp and the red is the zs3. There is 2 way protocol communication for about 15 seconds then the netapp sends a reset. --Jordan toaster*> ndmpcopy -d -da user:pass /vol/vm_store101 zs31:/export/test123/ Ndmpcopy: Starting copy [ 24 ] ...

Verifying nfo status for interfaces
by Jeff Cleverley 04 Sep '14

04 Sep '14

Greetings, We have a 7-mode, 8.1.2P4 cluster with several interfaces configured. There is no mention of nfo in the rc file. We need to down an interface for an old subnet but need to verify this won't cause a cluster failover. I haven't found what the default behavior for an interface is if it is not specified. I assume it defaults to the network options listed below. The takeover options are set for this: cf.takeover.on_network_interface_failure on cf.takeover.on_network_interface_failure.… [View More]
