Sorry there was a typo - "lvs" looks like this:

  LV                   VG     Attr      LSize   Pool      Origin Data%
 Move Log Copy%  Convert
  thin_pool            lxc1   twi-a-tz- 800.00g                    0.00

  glusterfs            lxc2   Vwi-aotz- 300.00g thin_pool          1.61

  glusterfs-test       lxc2   Vwi-a-tz-  10.00g thin_pool          1.28

  storage01-jobs2-prod lxc2   Vwi-a-tz-  30.00g thin_pool          3.99

  thin_pool            lxc2   twi-a-tz- 800.00g                    0.77

  home                 system -wi-ao---   4.77g

  var_log              system -wi-ao---   3.81g


here is my fstab:
#> cat /var/lib/lxc/storage01-jobs2-prod/fstab
/srv/glusterfs srv/glusterfs none bind 0 0
/dev/mapper/lxc1-glusterfs--test srv/glusterfs-test ext4 0 2
