Ich wollte heute dem rpool auf einem OpenIndiana-System (151a3) eine weitere Festplatte hinzufügen um einen mirror draus zu machen. Die Festplatte war bereits vorher in einem Raid-Z-Verbund im Einsatz gewesen und hierdurch bereits mit einem EFI-Label versehen:
# fdisk /dev/rdsk/c4d0p0
Total disk size is 60800 cylinders
Cylinder size is 16065 (512 byte) blocks
Cylinders
Partition Status Type Start End Length %
========= ====== ============ ===== === ====== ===
1 EFI 0 60800 60801 100
SELECT ONE OF THE FOLLOWING:
1. Create a partition
2. Specify the active partition
3. Delete a partition
4. Change between Solaris and Solaris2 Partition IDs
5. Edit/View extended partitions
6. Exit (update disk configuration and exit)
7. Cancel (exit without updating disk configuration)
Enter Selection:
Der erste Fehler den ich gemacht habe, war das ganze Device (z. B. c4d0) hinzufügen zu wollen: Ein root pool muss auf einer Disk mit slices (also z. B. c4d0s0) installiert werden anstatt auf einer ganzen Festplatte (siehe hier):
# zpool attach rpool c5d0 c4d0
cannot label 'c4d0': EFI labeled devices are not supported on root pools.
Der slice c4d0s0 existiert nicht und muss erzeugt werden. Ausserdem kann man Solaris nicht von EFI-Partionen booten, so dass zuvor eine Solaris2-Partition auf der Festplatte erzeugt werden muss:
# fdisk -B /dev/rdsk/c4d0p0
Im nächsten Schritt wird der benötigte slice erzeugt. Zur besseren Übersicht habe ich nach jeder Eingabe einen neuen Code-Block angefangen:

Jetzt kann man das zweite Device zum rpool hinzufügen:
# zpool attach -f rpool c5d0s0 c4d0s0
Make sure to wait until resilver is done before rebooting.
Mit zpool status kann man sich den Fortschritt des Resilver-Prozesses anschauen:
# zpool status
pool: rpool
state: ONLINE
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

Nun noch Grub installieren, damit die zweite Platte im Ernstfall auch bootfähig ist:
# installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c4d0s0
stage2 written to partition 0, 275 sectors starting at 50 (abs 16115) stage1 written to partition 0 sector 0 (abs 16065)
