ZFS Nexenta: please advise howto add a disk to pool (forced command line)

Hi,

ZFS Nexenta: please advise howto add a disk to pool (forced command line).


setup volume syspool via ssh gives me option to add extra disk but because size is different, it tells me to use -f (force) option. However, I don't find this option.

Existing LUN                : c0t5d0
New LUN to attach           : c0t4d0
Attach 'c0t4d0' to form a mirror configuration (or be added into existing mirror, if it exists) alongside 'c0t5d0' in the volume 'syspool'?  Yes

  Make sure that 'c0t4d0' is not part of an exported volume. Hint: use
  -f (force) option to ignore the warning and carry out the operation.

Note: any risks on putting two different sizes of disks as mirrored disk?

Please advise.
J.

Note:

admin@Nexenta:~$ zpool attach syspool c0t5d0 c0t4d0
cannot open 'c0t4d0': no such device in /dev/dsk
must be a full path or shorthand device name

Note: c0t4d0s0 is part of exported or potentially active ZFS volume syspool

in nexenta you use the command

setup volume, when you use this command you will see options

select syspool with the arrow keys, and then select

attach-lun

then select existing LUN (disk)

then select the New LUN to attach

or full command

setup volume syspool attach-lun

have you tried -f ?

There is no possibility to use -f. When you enter setup volume there is a menu driven option only.

setup volume syspool attach-lun -f works fine but destination volume is to small .... It took my 250 GB SATA disk as first one, now it can add the 100 GB SATA as second one. Will have to start all over :-)
