Linkedin group
by Nicholas Bernstein 05 Sep '08

05 Sep '08

Hi all, I didn't happen to see a toasters group on linkedin (the professional networking site) so I made one. Thought it might be of interest to some folks on the list. http://www.linkedin.com/groups?gid=751357 If this is objectionable to the group, I will, of course, remove it. Linkedin, oddly, requires manual approval, so if you don't get approved right away, it's just because I haven't gotten to it... I'll approve all comers, unless list admin's care to take over the management of the linked in group, in which case, I'll happily hand it over to someone else. Cheers, Nick -- Nicholas Bernstein Technologist, Consultant, Instructor http://nicholasbernstein.com

Noob...
by David.Ashton＠rullion.co.uk 04 Sep '08

Hi, please excuse my noobness, I've recently inherited a Netapp system or 3, I'm fairly new to SANs in general and netapp in particular. This isnt my full time gig (storage), its one thing amongst the 2 thousand other things I'm working on today, but I allocate a fair amount of time to figuring this stuff out. I'm struggling with something I'm sure all netapp storage people go through, I've read the manuals, I've played around for about 6 months on the filers and I cant answer this. I have a FAS3020. I have a volume, lets call it vol_bond. Its 820GB, 20% snap reserve. It contains one lun, which is 320GB. The space guarantee is volume, and fractional reserve is 100. Currently, there are 5 snapshots, totalling 8GB. It is snap mirrored to another filer. Snapshots are created nightly, there are no problems with that. At weekends, after various backup activity, these grow to about 80GB, but we only keep 5 and they're deleted. Its all up and running, everythings fine. Except for the filer status which reports: /vol/vol_bond is full (using or reserving 98% of space and 0% of inodes, using 49% of reserve) and the df -r output is /vol/vol_bondv8/ 687865856 670681368 17184488 335194536 /vol/vol_bondv8/ /vol/vol_bondv8/.snapshot 171966464 14140040 157826424 0 /vol/vol_bondv8/.snapshot What am I missing? I thought I had this thing nailed but obviously not.

Re: Oddball SnapMirror issue - Fixed
by Raj Patel 31 Aug '08

31 Aug '08

Old issue I know, but in case anyone else was interested - * Upgrading from 7.06 to 7.2.5.1 fixed it. So I'm unsure if there was a bug in 7.06 SnapMirror or if 7.2.5.1 just has a more robust SnapMirror but upgrading destination and source certainly fixed it. Cheers, Raj.

RE: issues with 10G Ethernet.

Hi. Wow you're down the street. I have about 250 VMs on 5 servers (IBM x3850m2 with 4 quadcore processors and 64 gig of RAM.

I have a call open with netapp about this however I thought I would ask the list if anyone else has had similar issues. We have a cluster which is connected to our core via TOE-10G Ethernet (T320E-XFP). The problem we see is that the sometimes the netapp appears stop receiving any packets. I haven't done a packet trace while the problem is in effect as I have been a bit of a Muppet when I have noticed the problem as I had forgotten the rlm user name but I have made notes so next time it happens I will do a trace.. This has happened on both units in our cluster. We have replaced one of the 10gig cards and that has made no difference. Our networking people show no errors on the line cards. Power cycling the units brings the network card back. We have turned toe off on the cards and that appears not to make any difference to the reliability of the system.

RE: issues with 10G Ethernet.
by Glenn Walker 28 Aug '08

Negotiated failover is something I'd rather not invoke: we have a network team here that I'm not a part of and my experience with EVERY network admin has been "the problem is not the network, it must be you" even with all the proof in the world of the network issue - including telling them how to fix their own problems. It's not quite that bad here, but we've had issues where ports have dropped unexpectedly and I really don't want a cluster failover to have to deal with as part of the overall issue. That said, it's a great option, but it doesn't work for my environment due to the split nature of the teams (and even if it wasn't I'd still be hesitant). -----Original Message----- From: Kevin Graham [mailto:kgraham@industrial-marshmallow.com] Sent: Wednesday, August 27, 2008 3:29 PM To: Glenn Walker; James Beal; toasters(a)mathworks.com Subject: Re: issues with 10G Ethernet. > We're using the dual-port 10GbE TOE cards with no issues - that said, > TOE is not enabled because we're using VIF (Filer turns TOE off with VIF > - not desired by us, but no choice right now as we cannot have SPOF). We've addressed this instead by using negotiated failover, both for 10GbE's and to convert failover 2x1gb's to single 4x1gb's; losing the switch the filer's uplinked to is rare enough of an event that (IMHO) a failover is acceptable. > Perhaps disabling TOE would get you more reliability? I'm still waiting for jumbos on the TOE to be stable...

Snapvault -- destination was 100%
by Willeke, Jochen 26 Aug '08

26 Aug '08

Hi toasters, we have seen several times where a snapvault destination gets filled up to 100% while an update on the sv-relation was running. Afterwards we see the snapvault relation in a quiescing mode. Doing some slow transfer: source:/vol/exvs13_db/mb1_3_sg1 destination:/vol/pdbnab5_v002/mb2_3_sg1 Snapvaulted 82:41:00 Quiescing (27 GB done) In the logs i see this: snapvault: vol=pdbnab5_v002 snapshot= op=2, giving up on update of /vol/pdbnab5_v002/mb2_3_sg1: could not read from socket When i abort the snapvault relation i see this: nstore1> snapvault abort nstore1:/vol/pdbnab5_v002/mb2_3_sg1 nstore1> Tue Aug 26 09:31:50 CEST [worker_thread_729:notice]: snapmirror: Network communication error And snapvault status shows the qtree in normal quiescing again, but it starts soon again to do a transfer.
