I'm running Ubuntu Server 13.04 64-bit using native ZFS. I have a zpool consisting of 4 hard drives of which one died yesterday and now is not being recognized by the OS or the BIOS anymore.
Unfortunately I saw the problem only after the next reboot so now the drive label is missing and I can't replace the disk using the official instructions here and here.
zpool status hermes -x
prints
root@zeus:~# zpool status hermes -x
pool: hermes
state: DEGRADED
status: One or more devices could not be used because the label is missing or
invalid. Sufficient replicas exist for the pool to continue
functioning in a degraded state.
action: Replace the device using 'zpool replace'.

I already replaced the drive with a new one (which got the label /dev/disk/by-id/ata-ST3500320AS_9QM03ATQ
)
Any one of the commands
zpool replace hermes /dev/disk/by-id/ata-ST3300831A_5NF0552X /dev/disk/by-id/ata-ST3500320AS_9QM03ATQ
zpool offline hermes /dev/disk/by-id/ata-ST3300831A_5NF0552X
zpool detatch hermes /dev/disk/by-id/ata-ST3300831A_5NF0552X
fails with
root@zeus:~# zpool offline hermes /dev/disk/by-id/ata-ST3300831A_5NF0552X
cannot offline /dev/disk/by-id/ata-ST3300831A_5NF0552X: no such device in pool
because the label of the drive that died does not exist in the system any more.I also tried the commands above omitting path to the drive's label to no avail.
How can I replace the "ghost" disk?
