I'm wanting to migrate raid levels on a zpool and I'm wondering the
best way to move data off a vdev. What I would like to do is this:
- Add a mirror vdev to the pool as a temporary location for my data,
- Move the data from the old vdev to the temporary vdev,
- Create new vdevs for the preferred raid configuration,
- Move data from temp vdev to new one.
Is this possible? Seems like it should be. If it is possible, how
would I do it?
No. Unless something changed and I missed the memo, ZFS doesn't support
mirrors of vdevs, only mirrors of devices.
