After that, you can shuffle the drives around in the system, and the pool
will continue to work correctly.

ooooooo! i wish i had understood that when i built a large set of
mirrored raid.

any way to hack it ex post facto?


Yep. It's as simple as:

* label all the drives using glabel, while they're still attached to the
pool
* use "zpool replace pool ad4 label/disk01" to replace 1 drive
* wait for it to resilver
* use "zpool replace pool ad6 label/disk02" to replace the next drive
* repeat the resilver and replace until all the devices are replaced

This is what I did to one of our servers. Works quite nicely.

There's no need to detach anything.
