compression DOT 8.1-7mode
by Klise, Steve 09 Aug '12

09 Aug '12

Has anyone turned on compression on their primary storage for DOT 8.1x 7-mode? I am upgrading our heads (6040's) to 8.1p2 and wanted to know what others are using.. These filers are primarily used for FC and VMWare with mostly Windows boxes with 60% dedupe savings. Its also acts as an Exchange CCR for Exchange 2007... I read the TR that shows the gains (if any) that is on the NOW site.. Any info and or opinions is appreciated in advance.

e0M port as default gateway?
by Ray Van Dolson 09 Aug '12

09 Aug '12

Hello all; We have some N6240's (rebadged FAS3xxx series) on which the default gateway is set to an IP that routes out the e0M interface. As such, if the e0M port (wrench port) goes offline, essentially functionality on that controller ceases as communication with AD, NIS, etc. stops working. We have 10GbE ports on these devices -- we could easily configure the default gateways to use one of those instead, but I am unclear as to what best practice is here. We access management functionality through the IP bound on the e0M port now. How do the rest of you set things up? Ray

Arp broadcasts from single vifs
by Jeff Cleverley 08 Aug '12

08 Aug '12

Greetings, I thought I posted about this a while back but don't seem to be able to find anything in my email or web searches. My apologies if this is a duplicate. We have some 7.3.5.1P4 filers running static multimode vifs, combined into a second level single vif for failover. One vif has 4 or 6 1gig links, and the other is a 10gig network port. We use the prefer to run the 10gig as the primary. All this seems to work fine and pulling cables, etc fails over properly. My question is whether there is another way to set up a failover configuration where the inactive links are not broadcasting the "who has xxx" arp requests every 5-6 seconds? With 20 standby links, this generates ~345K broadcast per day. This is causing arpwatch to create a very large file and be moderately useless due to the noise. We do have switches that could do LACP/dynamic multimode, but the network guide says these cannot be put in a second level vif. Is there anything we can do to get failover vifs and not have all the chatter? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

non disruptive HBA card installation on FAS3170 possible?
by Steve Losen 07 Aug '12

07 Aug '12

Hi folks, I kind of doubt that this is possible since our FAS3170 pair is in the same physical box and the power supplies are shared by both controllers, etc. If I am wrong, then how do you do it? Power down one controller with the RLM ? Then how do you install the HBA without disrupting the other controller?

8.1 performance improvments?
by Randy Rue 07 Aug '12

07 Aug '12

Hello All, We're in the initial stages of planning an upgrade of our v3170 pair (a 3Par T800 behind it) from 7.3.5.1P5 to (probably) 8.1P2 7-mode or higher. Our reasons include larger aggregates, some better troubleshooting tools that NetApp has told us will help figure out some ongoing issues, and especially a hoped-for performance improvement due to more legacy code having been updated to fully use multiple procs instead of living in the Kahuna namespace and locking onto CPU3. Again, this is what we've heard from the vendor. Can anyone offer experience with performance changes when upgrading from 7.x to 8.1? Ignoring the performance problems (I've seen a couple of KB articles) that are fixed by P2? Anecdotal experience would be a start but real numbers would be outstanding. Hope to hear from you, Randy Rue

Identify a heavy CIFS hitter on a vfiler?
by Randy Rue 06 Aug '12

06 Aug '12

Hello All, Got a v3170 cluster running 7.3.5.1 where one vfiler is seeing heavy CIFS traffic sufficient to drag the whole node to its knees periodically. Is there a way to identify the files/folders or CIFS clients that are doing the damage? Hope to hear from you ASAP, Randy Rue

How many retries on a disk before you pre-fail?
by Fletcher Cocquyt 04 Aug '12

04 Aug '12

I ran a syslog search for "retry" on this 3270 head for the last 7 days to get these disk retry messages: Aug 3 20:55:29 [na04:scsi.cmd.retrySuccess:debug]: Enclosure services device 3a.03.99: request successful after retry #1/#0: cdb 0x3c (1301). then get a frequency count to find chronic retry disks. awk '{print $12}' irt-na04.retry | sort | uniq -c | sort -nr 15 3a.06.99: 14 3a.05.99: 13 3a.03.99: 11 3a.04.99: 10 3a.02.99: 10 3a.01.99: 9 3c.00.99: 7 0a.08.99: 6 0a.07.99: 4 3a.08.99: 3 3a.07.99: 3 0b.00.99: 3 0a.05.99: 3 0a.03.99: 2 0a.06.99: 2 0a.04.99: 1 0a.02.99: 1 0a.01.99: Q: what level of retries should we look at pre failing a disk and replacing it proactively? Will the retries cause performance issues if ignored? thanks, Fletcher

shrinking volumes on 8.1?
by Randy Rue 01 Aug '12

01 Aug '12

What factors do I need to consider when resizing a volume downward? Will I always be able to shrink an over provisioned volume down to near the size used or do I need to worry about fragmentation or the WAFL equivalent? I ask because we've been using thin provisioning on a new filer in cases where we sense the customer might be overestimating their need (I know we're the only shop where this happens). But now that filer is about half full and we'd rather not need to stress over whether it's oversubscribed if we could just make it all Thick and reclaim any hoarded space when we need to.

After opening support cases at netapp one of the engineers told me that they also gets alot of performance cases with this release an even though he can't find a bug that feets with our logs and perfstat he recommend upgrade to 8.1.1rc1 Following his advise after upgrade I saw major performance improvment I mean throughput went up from 70-80 MB/s to 250-300 MB/s and latency also went down The same result occurred on more then one 8.1 system after upgrade to 8.1.1rc1 I saw at least 50% improvment in throughput Today on new system I install I completely skip th GA version an go straight to 8.1.1rc1 So my advice if you on this release and suffering from performance and don't know if you have enough disks or the right controller upgrade first then check Sent from Samsung Mobile
