Issue moving large snapmirror destination
by BERNTSEN Basil 19 Jan '17

19 Jan '17

Hi folks, I'm managing a 7-mode system (8.1) with a snapmirror destination of 35TB. I need to move it to a new aggregate on the same head. I really want avoid rebaselining from prod... I've tried a snapmirror cascaded off the normal destination, however it will likely take 4 days to complete using the internal loopback. While this is running, snapmirror scheduled updates to the normal destination volume don't run. I also tried a vol copy, but that seems to require you to keep a CLI session online for the whole transfer. Once it is copied with snapshots to the new aggregate, I'm going to change the source in the snapmirror.conf file. Does anyone have any ideas about how I could move this? Thanks!

Snapvault including old Snapshots?
by Alexander Griesser 12 Jan '17

12 Jan '17

Hi, I'm not sure if this is possible with SnapVault, but I would need to snapvault an existing volume which does currently have old sv_daily Snapshots on it, here's the output of "snap list": %/used %/total date name ---------- ---------- ------------ -------- 0% ( 0%) 0% ( 0%) Jan 09 10:00 hourly.0 0% ( 0%) 0% ( 0%) Jan 09 06:00 hourly.1 0% ( 0%) 0% ( 0%) Jan 09 00:00 nightly.0 0% ( 0%) 0% ( 0%) Jan 08 22:00 hourly.2 0% ( 0%) 0% ( 0%) Jan 08 18:00 hourly.3 0% ( 0%) 0% ( 0%) Jan 08 00:00 nightly.1 0% ( 0%) 0% ( 0%) Jan 07 00:00 nightly.2 99% (99%) 55% (55%) Jun 17 17:00 sv_daily.0 99% ( 0%) 55% ( 0%) Jun 16 17:00 sv_daily.1 99% ( 0%) 55% ( 0%) Jun 15 17:00 sv_daily.2 In fact, I would only be interested in sv_daily.2. Any chance to do that with SnapVault or maybe SnapMirror or would I have to clone the snapshot on the source volume into a new volume and transfer the volume created out of sv_daily.2 then?

prototyping opportunity - NetApp with Service-Now
by Weihs, Yossi 11 Jan '17

11 Jan '17

Hello As you may know, our own NetApp IT uses Service-Now extensively to maintain its large number of FAS / ONTAP systems ( see the following marketing message at http://www.servicenow.com/customers/netapp.html ). One of the NetApp engineering teams is now working on a prototype integration with Service-Now which will automate the creation of support action tickets (such as replacing a failed power supply) - the goal being to automate more work by syncing up NetApp ASUP cases with the customers Service-Now system. No commitment to having a production product - we are exploring market demand. Please respond directly to my email if you are interested in helping us by participating in (1) providing feedback to the concepts, 30-60 minutes webex (2) have Service-Now and want to experiment with ticket automation (scope TBD ) Happy new year, Joseph "Yossi" Weihs Sr. Manager, Product Management Data Fabric and Manageability Group NetApp

re-purposing older NetApps?
by Patrick Giagnocavo 11 Jan '17

11 Jan '17

Curious, what happens with older NetApps - is there a way to re-purpose them that makes sense? I have been told that the DS14MK2-AT shelves can be used as JBOD disk shelves with regular non-Netapp-firmwared drives - is this true? If so, would it support the >2TB drives that are out these days? (I have access to a 6 or 7 shelf 3070 with 56x1TB drives and some 500GB's ; what scares me is not the size of the rack, but the size of the likely power bill! ) Cheers Patrick

Atomicity of rename on NFS
by Edward Rolison 03 Jan '17

03 Jan '17

Hello fellow NetApp Admins. I have a bit of an odd one that I'm trying to troubleshoot - and whilst I'm not sure it's specifically filer related, it's NFS related (and is happening on a filer mount). What happens is this - there's a process that updates a file, and relies on 'rename()' being atomic- a journal is updated, and then reference pointer (file) is newly created, and renamed over an old one. The expectation is that this file will always be there - because "rename()" is defined as an atomic operation. But that's not quite what I'm getting - I have one nfs client doing it's (atomic) rename. And another client (different NFS host) reading it, and - occasionally - reporting 'no such file or directory'. This is causing an operation to fail, which in turn means that someone has to intervene in the process. This operation (and multiple extremely similar ones) happen at 5m intervals, and every few days (once a week maybe?) it fails for this reason, and our developers think that should be impossible. But as such - it looks like a pretty narrow race condition. So what I'm trying to figure out is first off: - Could this be a NetApp bug? We've moved from 7 mode to CDOT, and it didn't happen before. On the flip side though - I have no guarantee that it 'never happened before' because we weren't catching a race condition. (moving to new tin and improving performance does increase race condition likelihood after all) - Could this be a kernel bug? We're all on kernel 2.6.32-504.12.2.el6.x86_64 - and whilst we're deploying Centos 7, all the hosts involved aren't yet. (But that's potentially also just coincidence, as there's quite a few hosts, and they're all the same kernel versions). - Is it actually impossible for a file A renamed over file B to generate ENOENT on a different client? Specifically, in RFC3530 We have: " The RENAME operation must be atomic to the client.". So the client doing the rename sees an atomic operation - but the expectation is that a separate client will also perceive an 'atomic' change - once the cache is refreshed, the 'new' directory has the new files, and at no point was there 'no such file or directory' because it was either the old one, or the newly renamed one. Is this actually a valid thing to think? This is a bit of a complicated one, and has me clutching at straws a bit - I can't reliably reproduce it - a basic fast spinning loop script on multiple client to read-write-rename didn't hit it. I've got pcaps running hoping to catch it 'in flight' - but haven't yet managed to catch it happening. But any suggestions would be gratefully received.
