Description of problem: Snapshot creation fails with incorrect output with older selinux-policy Version-Release number of selected component (if applicable): glusterfs-3.7.5-8 How reproducible: Always Steps to Reproduce: 1. Create a snapshot of the volume when selinux-policy on the node is not updated. 2. Observe that the snapshot creation fails with "snapshot create: failed: Snapshot is supported only for thin provisioned LV. Ensure that all bricks of v1 are thinly provisioned LV." even when the bricks are thinly provisioned. Actual results: snapshot creation fails with "snapshot create: failed: Snapshot is supported only for thin provisioned LV. Ensure that all bricks of v1 are thinly provisioned LV." even when the bricks are thinly provisioned. Expected results: Return proper error related to permission of selinux Additional info: details from the machine: [root@dhcp43-185 ~]# rpm -qa | grep selinux selinux-policy-3.13.1-23.el7.noarch libselinux-python-2.2.2-6.el7.x86_64 libselinux-2.2.2-6.el7.x86_64 selinux-policy-targeted-3.13.1-23.el7.noarch libselinux-utils-2.2.2-6.el7.x86_64 [root@dhcp43-185 ~]# gluster snapshot create snap3 v1 snapshot create: failed: Snapshot is supported only for thin provisioned LV.
