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 coincidental. Anyone aware of snaprestore (specifically, single-file restores) causing cascading impacts? OnCommand doesn't show any additional spike in CPU, disk activity, etc.... Thanks, Ray

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

First time CIFS setup
by Fletcher Cocquyt 12 Sep '14

12 Sep '14

We are an NFS via vfilers shop, but had our first client request for a CIFS share. I’ve setup a CIFS vfiler using the local account/password option. cifs-vf-01@irt-na06> cifs shares Name Mount Point Description HOME /vol/media1/home Default Share everyone / Full Control We can map the share, but get “the disk is write protected” when attempting a copy to the mapped drive. The error the client receives when trying to map the drive is "The account is not authorized to log in from this station” I’d like to resolve both our “write protected” and the client’s “not authorized” errors - why are these errors if the HOME share is created as “everyone / Full Control” ? Any advice/links appreciated thanks, Fletcher.

Re: rename administrator user

The (windows) client ended up renaming their account to ‘admin’ to avoid the match and allow anonymous mapping thanks On Sep 9, 2014, at 7:30 PM, Fletcher Cocquyt <fcocquyt(a)stanford.edu> wrote: > > > > On Sep 9, 2014, at 4:04 PM, Fletcher Cocquyt <fcocquyt(a)stanford.edu> wrote: > >> To avoid a match of the account on the cifs client I’d like to rename the netapp administrator account. >> >> Docs say its possible: >> https://library.netapp.com/ecmdocs/ECMP1196891/html/GUID-BAB0B59B-4BA5-4165… >> >> I can’t seem to find the method/cmds >> >> thanks! >> >> >> >> >> >> _______________________________________________ >> Toasters mailing list >> Toasters(a)teaparty.net >> http://www.teaparty.net/mailman/listinfo/toasters >

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.policy all_nics (same value in local+partner recommended) This seems to tell me that all_nics have to fail before a failover would occur. It also looks like I could run a manual ifconfig command and apply the -nfo to be on the safe side. I'd like to get a sanity check that downing the one interface won't cause a failover and that a manual change to an interface using -nfo would fix it anyway. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

Re: ndmpcopy from netapp to oracle zs3?
by Jones, Brian 03 Sep '14

A few years back the Oracle ZFS storage had a feature called Shadow Copy. It was a pretty good method to move data from any NFS storage into the ZFS storage. Basically, you would create a new volume on the ZFS storage and point it at the source. In the background it would copy data to the ZFS storage and proxy any requests through to the old storage for data that was not yet migrated to ZFS. This was how we migrated a number of Oracle databases with minimal downtime. This only worked for NFS. CIFS or block storage still had to be copied at the client level. --Brian

FAS2040 NVMEM Battery
by Camillo Gornati 26 Aug '14

26 Aug '14

Is the FAS2040 Battery the same as FAS2020? I've been told they are the same, but as i do have them both, i checked on FAS2020 the code is 271-00010 and on the FAS2040 the code is 271-00024. I need to be sure, because i need to replace the FAS2040 battery and i am only able to find the part #271-00010 (FAS2020). A friend told me it is supposed to be the same, but i need to be sure. Thanks in advance.
