NSF client listing
by Weasner, Matthew K 19 Oct '12

19 Oct '12

This is probably a silly question, but what is the most reliable way to get a list of NFS clients that have an export mounted? OnTap 7.3.3, and the share is exported R/W to the world.

is the filer "telnet' command
by Iluhes 03 Oct '12

I need to check if the firewall is open between filers on snapmirror ports. I cannot find a "telnet" command so I can telnet from fi ler to to filer on specific port. How do I check from filer CMD line if the ports on the snapmirror partner are open Thanks!

Re: e0M port as default gateway?

We are running cluster mode on these systems (two controllers). Key thing we're seeing is that NFS/CIFS file serving activity grinds to a halt when we lose connectivity to AD/NIS servers (the communication for which currently goes through e0M due to default gateway setup). I presume this is expected behavior, but am a bit surprised that NFS file serving would hang for activity not involving an NIS UID. Presumably any NFS requests gets mapped to a UID and would require an NIS lookup? Anyone run into this before?

CIFS with Unix sec. style and recent MacOS 10 and MS Word
by Steve Losen 11 Sep '12

11 Sep '12

Hi Toasters, We are sharing a Unix sec. style qtree to (at least one) MacOS 10.7 client via CIFS and they are having problems saving files with MS Word. The client writes the new file to a temporary file and then fails to rename it into place. The temp file exists and is correct because we can verify this from a NFS client. A Unix sec. style share appears to be a VFAT (not NTFS) volume to a CIFS client. Under the hood the filer enforces Unix permissions, of course, but all that is hidden from the CIFS client. I suspect that MacOS is looking for a permission that VFAT does not support and is erroneously assuming it cannot rename the file. Just curious if this rings a bell with anyone and if there is any documentation or workaround for it. We are running DOT 8.0.1 7mode on the filer. I need to get together with the user who is having trouble and use the sectrace command to see if the filer is actually denying access.

ipspaces vs static net routes
by Fletcher Cocquyt 06 Sep '12

06 Sep '12

Hi we are running 8.1 on our 3270 clusters with 17 vfilers on 5 different vlans The vfilers currently share the same default IPspace and we are (understandably) seeing routing issues (asymmetric routing) when NFS clients outside the vFiler's vlan attempt to communicate with the vFiler. (these clients are the exception > 95% of clients are in the same routable net and don't have any issues) What are the opinions about adding new IPspaces vs just adding 5 static net routes to the shared routing table so routing works? thanks, Fletcher

Hi, Does anyone know of a way to schedule the snapmirror initialization? I know the updates can be scheduled in snapmirror.conf, but goes to Pending if initial sync not done first. TIA Kevin

mixing DS4243 and 2246 SAS shelves
by Fred Grieco 27 Aug '12

27 Aug '12

Does anyone know the risks or reasons why you shouldn't mix DS4243 and DS2246 SAS enclosures in the same stack? We have an IBM N6040 (3140) which inadvertently has this configuration and is running without issue... TIA, Fred

8.1.1 went GA today - decided to stage it on our DR 2240 Its rolling through some disk firmware updates now - how disruptive are these ? Will they add Disk IO when I upgrade my prod clusters? If its doing a raid group reconstruction for each, how are they so quick?

Good day. Search a lot, but found no any clue: is it possible to use ssh keys to log to SP instead passwords? Thanks.

Snapmirror within same controller
by Kevin Richards 16 Aug '12

16 Aug '12

Hi, When you snapmirror on a single controller from aggr1 to aggr2, does it use loop back? And is there a limit on throughput then? Thanks Kevin
