SOLVED Expanding Volume

[rwakc]

Hi,

I have this volume called HDD and I would like to extend it. There seems to be about 3TB of EXPANDSZ space, but I do not see an option to extend it.

If I can do anything to reduce fragmentation, any advice would be very welcome as well.

Code:

root@freenas:~ # zpool list
NAME		   SIZE  ALLOC   FREE  EXPANDSZ   FRAG	CAP  DEDUP  HEALTH  ALTROOT
HDD		   7.94T  7.69T   254G	 2.94T	61%	96%  1.00x  ONLINE  -
freenas-boot  7.94G   744M  7.21G		 -	  -	 9%  1.00x  ONLINE  -

Code:

root@freenas:~ # zpool status
  pool: HDD
 state: ONLINE
  scan: scrub repaired 0 in 17h39m with 0 errors on Sun Jun  3 17:39:17 2018

Dont run single disk vdevs, get yourself a second drive of the same size and add it as a mirror asap. Your data is at risk. Also, to expand simply add a second mirror to the pool

I have managed to expand the volume by using

Code:

zpool online -e <pool> <device>

Thank you for fast replies.
