+++ This bug was initially created as a clone of Bug #1178031 +++ 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.
