Hi,

I have a mirror pool with two drives:

    NAME                        STATE     READ WRITE CKSUM
>     xtbmr                       ONLINE       0     0     0
>       mirror-0                  ONLINE       0     0     0
>         sde                      ONLINE       0     0     0
>         sda                      ONLINE       0     0     0
>

I want to change the labels derived from disk-id. 'ls -la /dev/disk/by-id'
outputs:

lrwxrwxrwx 1 root root   9 Dec  2 08:08 ata-ST10000VN0004-1ZD101_ZA22435B
> -> ../../sde
> lrwxrwxrwx 1 root root  10 Dec  2 08:08
> ata-ST10000VN0004-1ZD101_ZA22435B-part1 -> ../../sde1
> lrwxrwxrwx 1 root root  10 Dec  2 08:08
> ata-ST10000VN0004-1ZD101_ZA22435B-part9 -> ../../sde9
> lrwxrwxrwx 1 root root   9 Dec  2 08:08 ata-ST10000VN0004-1ZD101_ZA224RJK
> -> ../../sda
> lrwxrwxrwx 1 root root  10 Dec  2 08:08
> ata-ST10000VN0004-1ZD101_ZA224RJK-part1 -> ../../sda1
> lrwxrwxrwx 1 root root  10 Dec  2 08:08
> ata-ST10000VN0004-1ZD101_ZA224RJK-part9 -> ../../sda9
>

How can I change the disk labeling

FROM sde TO ata-ST10000VN0004-1ZD101_ZA22435B
FROM sda TO ata-ST10000VN0004-1ZD101_ZA224RJK

without breaking the zpool?

Inputs appreciated and have a nice weekend!

Cheers,
/z
