vfiler migrate
by Randy Rue 08 Feb '12

08 Feb '12

A co-worker of mine already posted on this but we're coming up with more questions. We successfully tested the migration of a test vFiler from one node to the other and back. Took 3-4 minutes each way for a vFiler with one aggregate and two "disks" (it's actually got a 3Par SAN on the back end). Then we tried a vFiler with two aggregates of 14 and 15 "disks." It went from A to B with no trouble, took closer to six minutes. When moving it back from B to A it blew up. Got the following at the CLI: tungsten-a> vfiler migrate -m nocopy fhdata@tungsten-b tungsten-b's Administrative login: root tungsten-b's Administrative password: Stopping remote vfiler.... vfiler migrate: Aggregate 'fhdata_aggr1' has failed and cannot be brought online. Problem bringing aggr fhdata_aggr1 online: CR_VOL_FAILED vfiler migrate: No aggregate named 'fhdata_aggr2' exists. Couldn't find aggr fhdata_aggr2 in order to bring it online vfiler migrate: No volume named 'fhdata_root' exists. Couldn't find flex-volume fhdata_root in order to bring it online vfiler migrate: No volume named 'fhdata_shared' exists. Couldn't find flex-volume fhdata_shared in order to bring it online vfiler migrate: No volume named 'fhdata_viddshared' exists. Couldn't find flex-volume fhdata_viddshared in order to bring it online Problem bringing vfiler fhdata volumes online. tungsten-a> tungsten-a> vfiler status -r fhdata Vfiler not found: fhdata tungsten-a> At first there was no sign of the vFiler, aggregates or volumes on either A or B. After a few minutes, part of one aggregate was visible on A. A few minutes after that we could see both aggregates and all disks. Brought the aggregates online and the all the volumes. The vFiler is still gone, no sign of it on either node. Does the vfiler migrate command support vFilers with more than one aggregate? Note that all the volumes for the vFiler live on two aggregates and no other volumes are on those aggregates. While we're on the subject, does anyone know where the configs for a vFiler actually live? Right now my hope is to rebuild the vFiler and reattach the volumes but I'm hoping to at least be able to see what CIFS shares it had, for example. We save a nightly tarball of the complete contents of etc$ so if it's in a config file somewhere I can find it. On the phone with NetApp support right now but I'm hoping someone has experience with this in the real world. Hope to hear from you. Randy

Filer behavior differences between 7.3.3 and 7.3.5.
by Jeff Cleverley 07 Feb '12

07 Feb '12

Greetings, Has anyone upgraded from any version of 7.3.3 to a 7.3.5 variant seen any behavioral differences? I also upgraded diagnostics from 5.5 to 5.6.1. I upgraded 2 clusters from 7.3.3P5 to 7.3.5.1P4 at the first of the year. One cluster is a 6040 and the other is a 6080. Both have similar layouts of disk space and usage, CIFS, NFS, PAMII cards, 10G networking, etc. After the upgrade, the 6040 cluster is behaving normally. Our NMS monitoring server immediately started reporting SNMP polling timeouts for the 6080 cluster. There were over 130 errors for each head within the first 2 days and 0 for the entire month of December. The 6080 cluster has user home directories via NFS. I see periodic "hiccups" in response on my workstation, as have other users. We had one of the filers panic due to a failed SAS controller a couple of weeks after the upgrade. During that failover time, there were a lot more complaints about unacceptable performance until I got the replacement part and failed things back. I was able to pull a performance graph from the first of December to the end of January for both filers. This data came from SNMP queries of the filers. You can clearly see that the baseline CPU utilization was ~40% before the upgrade and ~60% after the upgrade. That would also account for the poor performance during the cluster failover since one filer head can't maintain the load (60%) for both heads without degrading performance. Through all of this, nothing changed but the OS and diagnostics firmware. I just reinstalled the OS again this weekend just to make sure everything was happy with it. There has been no change. I've got a call open with NetApp but they are not seeing anything wrong and are unable to explain what is driving the CPU higher since everything looks acceptable to them. Unfortunately I did not do a perfstat collection prior to the upgrade so there isn't anything to compare it to. I did find the option nfs.mountd.trace option became very verbose after the upgrade (prior post on that) and had to be turned off. I'm wondering if there are any other issues anyone else may have found after this type of upgrade? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

anybody has experience using snapmover?
by Kawakubo, Ken 06 Feb '12

06 Feb '12

Dear list, We have an active-active cluster with vfilers. One vfiler in node-1 is having performance issues. Since node-1's CPU usage is much higher than node-2. I would like to migrate the vfiler from node-1 to node-2. I found a feature called snapmover in vfiler manual. I found that the command "vfiler migrate -m nocopy" migrates a vfiler from node-1 to node-2 without actually copying data. This command merely changes the software disk ownership of disks that make up the vfiler and is non-disruptive. Furthermore, snapmover is now a non-license feature. Sounds too good to be true? I want to know if there is any gotcha using snapmover. Does anybody have experiences using "vfiler migrate -m nocopy" command? Our cluster is NetApp V3170. Regards, Ken Kawakubo

Volume Naming Conventions?
by Ray Van Dolson 04 Feb '12

04 Feb '12

Hello; Curious what type of volume naming conventions you all have found work best? We're about to expand our environment, and looking for ideas on ways to keep names somewhat formulaic and consistent across filers. Thanks, Ray

Hi Steven - thanks for the link - yes, I can get to it sound like I should add a license command prior to giveback to verify all the features I need are still licensed properly?

Justin, thanks for the feedback What makes step 13 (cf giveback) triggering another reboot of the SAME node A is step 12 reads like that has already been accomplished for node A so does node A reboot twice, then when you repeat the procedure, node B reboots twice? thanks -- Fletcher On Feb 2, 2012, at 11:20 AM, Parisi, Justin wrote: > In a takeover/giveback scenario, there are two reboots. > > The first reboot is the takeover.

clarification about reboots during NDU
by Fletcher Cocquyt 02 Feb '12

02 Feb '12

Hi - can someone clarify this from pg 56 of the upgrade guide - for instance, if step 12 causes A to "reboot the system using the new firmware and software" WHY in step 13 does the cf giveback ALSO "cause system A to reboot with the new system configuration?" Are there really 2 reboots ? thanks 12. Enter the following command to reboot the system using the new firmware and software: bye 13. Choose the option that describes your configuration. If FCP or iSCSI... Is not in use in system A Is in use in system A Then when the "Waiting for giveback" message appears on the console of system A... Enter the following command at the console of system B: cf giveback Wait for at least eight minutes to allow host multipathing software to stabilize, then enter the following command at the console of system B: cf giveback Attention: The cf giveback command can fail because of open client sessions (such as CIFS sessions), long-running operations, or operations that cannot be restarted (such as tape backup or SyncMirror resynchronization). If the cf giveback command fails, terminate any CIFS session or long-running operations gracefully (because the -f option will immediately terminate any CIFS sessions or long-running operations) and then enter the following command (with the -f option): cf giveback -f For more information about the behavior of the -f option, see the cf(1) man page. The command causes system A to reboot with the new system configuration—a Data ONTAP version and any new system firmware and hardware changes—and resume normal operation as a high-availability partner. -- Fletcher Cocquyt Principal Engineer Information Resources and Technology (IRT) Stanford University School of Medicine Email: fcocquyt(a)stanford.edu Phone: (650) 724-7485

NetApp recommends upgrading disk firmware the day before upgrading Data ONTAP
by Fletcher Cocquyt 02 Feb '12

02 Feb '12

I have downloaded the X410_HVIPC288A15 firmware - is this one truly non-disruptive? The online docs seem overly verbose - what is the short user test version for applying the disk firmware prior to 7.3.5.1P2->8.1RC2 NDU? thanks Upgrade These 96 disks will have firmware updates if the latest disk firmware is loaded on the filer: 96 disks of Model X410_HVIPC288A15. This firmware is not included in 8.1RC2 and must be downloaded separately. When performing a nondisruptive upgrade, NetApp recommends upgrading disk firmware the day before upgrading Data ONTAP. -- Fletcher
