no Data in Pool but is not empty

Post by Pappmann »

Hi,

i have a ZFS Pool named "Media" that is showing healthy and its mounted but no Data inside.

Code: Select all

  pool: Media
 state: ONLINE
  scan: scrub repaired 0 in 5h20m with 0 errors on Fri Oct 23 23:34:34 2015
config:

	NAME        STATE     READ WRITE CKSUM
	Media       ONLINE       0     0     0
	  ada1      ONLINE       0     0     0
	  ada0      ONLINE       0     0     0

errors: No known data errors
GUI is showing only 441G avalable Size

Code: Select all

Filesystem                     Size    Used   Avail Capacity  Mounted on
Media                          441G    100M    441G     0%    /mnt/Media
but "zpool list" shows the real Size and 2.2T used Space:

Code: Select all

 nas: ~# zpool list
NAME    SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
Media   2.72T 2.20T   528G     -        5%     81%  1.00x   ONLINE     /
Why that differences? How i can have back access to my data?

Im using nas4free version 10.2.0.2, but i had the same problem on 9.x before.

this means that you deleted that data.

the data should still be accessible in the snapshots

snapshots can be accessed from the .zfs/snapshot directory in the dataset
Nas4Free 11.1.0.4.4517. Supermicro X10SLL-F, 16gb ECC, i3 4130, IBM M1015 with IT firmware. 4x 3tb WD Red, 4x 2TB Samsung F4, both GEOM AES 256 encrypted.
