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. -- Freddie Cash fjwcash@gmail.com
