Description of problem: my bricks are on XFS on LUKS on thin-LV. creating a shapshot fails. Steps to Reproduce: 1. create bricks on thin-LV, but with additional LUKS encryption layer 2. gluster snapshot ... Actual results: snapshot create: failed: Snapshot is supported only for thin provisioned LV. Ensure that all bricks of storage_www are thinly provisioned LV. Snapshot command failed Expected results: snapshot Additional info: [2015-01-01 16:41:35.047033] E [glusterd-snapshot.c:1742:glusterd_is_thinp_brick] 0-management: Failed to get pool name for device /dev/mapper/data [2015-01-01 16:41:35.047128] E [glusterd-snapshot.c:2081:glusterd_snapshot_create_prevalidate] 0-management: Snapshot is supported only for thin provisioned LV.

hey, i'd like to know what the ETA for this issue is. we have a tight schedule and need to figure out whether we wait for a solution on your side, or we do the work of reconfiguring the storage, so that the crypto layer is below the thinpool. the trade-off is that we would need to backup the data before and migration in each direction will take two weeks.
'GlusterFS-3.6 is nearing its End-Of-Life, only important security bugs still make a chance on getting fixed. Moving this to the mainline 'version'.
Thank you for your bug report. Our recommended configuration is to layer LUKS below thin LV. Hence we will not be addressing this bug.
