Hi all,
The scenario:
1. You have an existing zPool containing one mirrored vDev of two 4TB disks. Total zPool storage 4TB.
2. You later add another mirrored vDev of two 12TB disks to the pool. Total zPool storage 16TB.
Now at a future date, you decide that due to over-provisioning of space, running the original pair of 4TB disks is a waste of energy and want to remove them from the zPool, but have the data on that 4TB vDev transfer over to the 12TB vDev mirror.
Is there any way to acheive this inside the ZFS system without copying the data out to another location and destroying the pool?
Thanks.
