adding a disk to a 2-way mirror to build 3-way

[Banagher]

Hi!

I am using NAS4Free 10.3.0.3 (2987)
There is a two way mirror (built with an older version of the web-gui) and an unused disk in the system.

Code: Select all

nas4free: ~# zpool status
  pool: rootvg
 state: ONLINE
  scan: ...
config:

        NAME          STATE     READ WRITE CKSUM
        rootvg        ONLINE       0     0     0
          mirror-0    ONLINE       0     0     0
            ada0.nop  ONLINE       0     0     0
            ada1.nop  ONLINE       0     0     0

disks_manage.php shows:

Code: Select all

ada0 	WDC WD30EFRX-68EUZN0 	2861589MB 	WD-WCC4N6NETL8L 	ahcich0 	Intel Cougar Point AHCI SATA controller 	Always On 	ZFS Storage Pool 	ONLINE 	Edit disk  Delete disk
ada1 	WDC WD30EFRX-68EUZN0 	2861589MB 	WD-WCC4N6KR54SX 	ahcich1 	Intel Cougar Point AHCI SATA controller 	Always On 	ZFS Storage Pool 	ONLINE 	Edit disk  Delete disk
ada2 	WDC WD30EFRX-68EUZN0 	2861589MB 	WD-WCC4N6TV68N0 	ahcich2 	Intel Cougar Point AHCI SATA controller 	Always On 	ZFS Storage Pool 	ONLINE 	Edit disk  Delete disk

How can I add ada2 to mirror-0 in order to build a 3-way mirror? From the command line I would issue zpool attach rootvg ada0.nop ada2 and be done with it.
This works but is not reflected in the web-interface. I tried "disks zfs configuration synchronise" but that didn't seem to update the vdev.

On the page "virtual devices" (disks_zfs_zpool_vdevice_edit.php?uuid=...) where i would expect it to happen, I don't find any way to accomplish that.


What am I missing?

Thanks in advance and thank you for writing excellent software.

zpool attach rootvg ada1 ada2 or zpool attach rootvg ada1.nop ada2.nop

So this means it's got to do with the dotnop devices.

Code: Select all

nas4free: ~# zpool attach rootvg ada1 ada2
cannot attach ada2 to ada1: no such device in pool

Obviously I can't attach to a device that is currently not in the vdev.

Thanks.
