Re: Redoing snapmirror to a destination

I just double checked and I don't have any common snapshots unfortunately. Time to file a req with netapp to make 'snap delete ...' Be less permissive in deleting snapshots used for any snap* relationships without a force switch of some sort...

If you have common Snapshots, you can issue a 'snapmirror resync' on the destination and the relationship will be established. This is better than swapping the volume because you'll likely get stale file handles. -- Michael Barrow michael at barrow dot me On Dec 7, 2009, at 2:50 PM, John Stoffel wrote: > > Guys, > > Do to stupidity on my part, I managed to accidently delete a snapshot > on the source side of a snapmirror pair, so that snapmirror can't > continue.

Hmmm fsid is something to keep in mind. I can do a couple of tests vols later to see what happens. Thanks for the feedback all!

The trick is to keep the fsid the same. I doubt the steps you outline will do that. Is it possible to tell a filer to use a particular fsid for a volume? (I guess snapmirror does not change inodes, what is also needed here.) Grtnx, -- Bert Kiers XS4ALL UNIX systeembeheerder, suspected terrorist 1984 was not meant as a manual

No common snaps that I know of, but its a good idea.

It's not critical, it's just our tools area, which isn't updated frequently. So now I want to re-snapmirror, but I want to limit the downtime of the clients on the destination side as much as possible when I switch them to the new re-snapmirrored volume. Currently, my clients mount east:/vol/tools, so what I'd like to do is: west> snapmirror store tools rst0a,rst1a east> vol create tools .... east> vol restrict tools east> snapmirror retrieve tools_new rst0a,rst1a Now for the tricky part: east> nfs off east> vol rename tools tools_old east> vol rename tools_new tools east> nfs on east> exportfs -a -v so that all my clients see (on a read-only volume) is a quick outage or pause in NFS traffic, then they just continue on using tools and such as usual. Or will I be forced to reboot all of my client machines one by one? Which will be truly truly truly painful... The general snapmirror update and cleanup of the old volume is trivial. It's limiting the outage to my clients that I worry about.

Does anyone know if the dedup is across the entire aggr or just the volume in 7.3.x?
by Page, Jeremy 07 Dec '09

07 Dec '09

Does anyone know if the dedup is across the entire aggr or just the volume in 7.3.x? I'd like to break up my VMware environment so we have a volume per service (so SQL Warehouse volume, Call Center etc). This would be nice because we could delegate the rights to them, move them around if specific apps required more IO and aid in troubleshooting. The question I have is will this kill our dedup percentages? Please be advised that this email may contain confidential information.

SMVI 2.0 problem
by steve klise 02 Dec '09

02 Dec '09

ok, scratching my head here... I just upgraded the new SMVI 2.0 with file level restore.. HURAYY.. Its only been a year, but I guess you cant rush perfection. I was previously running 1.2 and have the typical wait time errors, but for the most part is successful. Specs: ESX vshpere 4.0 (non 4i flavor) SMIV 2.0 (installed on VMWare VIC physical server) 6040's DOT 7.3.11 FC HP DL380s G5(for now) problem: When I try and do a single file restore via self service option, (to and from the same VM guest), I go to select the vm in the restore agent from the guest OS, I press OK. Then I get an error: Failed to retrieve backupList fro the source guest. And I only have an OK button. i have tried from multiple guest os'es. Same result. I looked in the log, and this is just before the popup I get: at RestoreAgentWCFSvc.RestoreAgent.GetBackupsAndDisks(GuestIdentifier guest, List`1& backupRootedHierarchy, List`1& diskRootedHierarchy, Exception& exFromHyperVisor) then the error in the log.. 11/23/2009 01:31:48:154 (PID:01684 ,TID:00006): Failed to retrieve backupList for the source guest Any help is appreciated.. -- View this message in context: http://old.nabble.com/SMVI-2.0-problem-tp26486178p26486178.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.
