If you have a SnapMirror license, I would do a qtree snapmirror. Set up an incremental schedule, say once an hour. Then when you're ready to cut the clients over, you'd only move an hour's worth of changes over which should be quick.

Hello experts,

I am very new to the netapp world. Sorry if this has been answered already or if it sounds stupid.I have the following situation,

What we have is a FAS940 with DS14MK2 shelves(3nos).

There is a qtree "proj-CFD" which is 200GB in size and the containing volume is 500GB. The volume is 90% full. I have been asked to increase the space for the qtree to 400GB. Previous admin created the aggregate(Aggr1) with a raidsize of 8 and there are two raidgroups with 8disks in each raidgroup.

I have three spares and adding these to the current aggregate would create another raidgroup of 3 disks and i will be left with 1 usable disk (we have raid_dp) and also i will have no spares left.

But fortunately there is another aggregate(Aggr2) with a raidsize of 16 and there are 14 disks in that aggregate now. Now my question is, how can move the "proj-CFD" qtree to a volume in Aggr2 with minimum downtime and keeping all the ACLs intact(It is ntfs only).

Thanks

-- With warm regards

Depending on the rate of change, file size and number of files in this Qtree, robocopy may work well. We generally use it to move large amounts of windows data between volumes/filers when we can't use snapmirror. It will keep the ACL information for you if you give it the right flags.

The first copy will take a while, but you can do file level incremental updates after that.

You can download it from Microsoft. It is part of the Windows Server 2003 resource kit. The kit includes a robocopy.doc word document that explains all of the flags.

At the time of the cut over, delete the share (after saving the share settings), do a final robocopy and recreate the share pointing to the new location.

Jeff.
