How do I change the mount point for a ZFS pool?

Question

example:

When I created the pool, I set it to mount to /mystorage

zpool create -m /mystorage mypool raidz /dev/ada0 dev/ada1 /dev/ada2

But now I want the pool to mount to /myspecialfolder.

Any ideas how it can be done? I've searched the net and look at zpool and zfs manpages and found nothing.

Thanks

I didn't realize I can change the mount point while the pool in in use. I thought I needed to export it first and then change the mount point during import. Thank you!

@mrjayviper If you use the normal commands (not special options like -F or similar) and stay away from destroy, you cannot do much harm on ZFS. If an operation is not possible, you would get resource busy, dataset in use or similar. Of course, this is only for the filesystem - your applications may react differently (should handle such events themselves).

zfs create -o mountpoint=/myspecialfolder mypool at create time
