First 3 disks in the vdev replaced without issues. 4th disk turned out to be a dud. Nothing but timeouts and read/write errors during the replace. So I popped it out, put in a different 1.5 TB drive, glabel'd it with the same name ... and the pool went "boom". Now I'm stuck with a "label/disk04" device that can't be replaced, can't be offlined, can't be detached. Tried exporting the pool, importing the pool, with and without the disk in the system. All kinds of variations on detach, online, offline, replace on the old device, the new device, the UUIDs. Nothing. [Now I know, for the future, to stress-test a drive before putting it into the pool.] I'm really hoping there's a way to recover from this, but it doesn't look like it. Will probably have to destroy/recreate the pool next week, using the 1.5 TB drives from the get-go. -- Freddie Cash fjwcash@gmail.com
