Description Stanislav Graf 2015-05-18 15:44:12 UTC

Description of problem:
=======================

When one hits Selinux Bug 1212923, oVirt reports:
~~~
Operation Canceled
Error while executing action Create Gluster Volume Snapshot: Snapshot create failed
error: Snapshot is supported only for thin provisioned LV_ Ensure that all bricks of volume1 are thinly provisioned LV_
return code: -1
~~~

engine.log says:

The message from oVirt is misleading.

Version-Release number of selected component (if applicable):
=============================================================
ovirt-engine-3.6.0-0.0.master.20150517172245.git089e126.el6.noarch

How reproducible:
=================
100%

Steps to Reproduce:
===================
1. Create a volume using at least one RHEL7 node
2. Selinux in enforcing mode on RHEL7 node
3. In oVirt -> Volume -> Snapshot -> New

Actual results:
===============
Misleading error message.

Expected results:
=================
More accurate error message.

Additional info:
================

Comment 1 Stanislav Graf 2015-05-18 20:23:01 UTC

Oh, this is a bug in gluster and not oVirt, see:
~~~
# gluster snapshot create test1 volume1
snapshot create: failed: Snapshot is supported only for thin provisioned LV. Ensure that all bricks of volume1 are thinly provisioned LV.
Snapshot command failed
(exitcode=1)
# setenforce 0
# gluster snapshot create test1 volume1
snapshot create: success: Snap test1_GMT-2015.05.18-20.19.13 created successfully
~~~

# rpm -q glusterfs
glusterfs-3.7.0beta1-0.131.gitf54b232.el7.centos.x86_64
