Reallocate Existing Volumes with Snapshots

Hello,

I've added several disks to an aggregate.   I'd like to reallocate existing volumes and snapshots of those volumes across the new disks in the aggregate.   Is there any way to reallocate a volume and its snapshots across the new disks in an aggregate?  

Everything I've come across seems to indicate that one must delete all volume snapshots before reallocating a volume across the new disks is possible.  I hope there is a way to reallocate volumes without deleting their snaps!  :-)

Thanks,

Jordan

Looks like I can use the -p option with the reallocate command.   (reallocate -p), Time to look into that option.

Re: Reallocate Existing Volumes with Snapshots

Yes, you can use the -p option, but make sure the volume has some extra free space as the snapshot sizes grow more than expected as this is a physical reallocation.

Re: Reallocate Existing Volumes with Snapshots

To redistribute data across disks you should use "reallocate -A". Simple reallocate will not touch snapshot data.

You should consider removeing aggregate snapshots, as reallocation will cause "growth" of them.
