1.  Create a new volume on aggr2 of the same size as aggr1
2.  Do a volume snapmirror of aggr1 to aggr2
3.  When ready to switch to the new aggr, do a snapmirror update
    a.  Ideally you would turn off CIFS
    b.  Rename the volume containing proj-CFD to some other name
    c.  Rename the new volume to the name of the old volume containing proj-CFD
    d.  Restart CIFS
4. If you can't turn off CIFS, then the rename will cause your shares to follow the old volume, so you will have to delete the old shares and create new ones.
5. Resize the new volume.
 
If you want to restrict the QTree to a specific size within the volume, you can setup a QTree quota..

Subject: copying qtree

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
