## plan
|
|
* rm one device (`wwn-0x5001b448b14c43cd-part2`)
|
|
* add it as a mirror with the tmp USB-connected device (`/dev/disk/by-id/ata-WDC_WDS240G2G0A-00JH30_19461B800819-part2`)
|
|
* rm the other device (`wwn-0x5001b448b143d092-part2`)
|
|
* swap the USB-connected device from the mirror using `replace`
|
|
|
|
**THE ABOVE IS WRONG**, what sufficed was:
|
|
* remove one of the drives
|
|
* do a `zpool attach zr <id of the drive left> <id of the drive to add>`, which
|
|
automatically forms a mirror!
|
|
* profit!!!
