Description Nitin Goyal 2018-05-08 08:52:32 UTC

Description of problem: Some times heketi is creating volumes and some times it give us error that "no space left" even though we have space left on devices.

Version-Release number of selected component (if applicable): 6.0.0.11

Actual results: It is creating volumes 4 times out of 10.

Expected results: It should create volumes every time.

Comment 2 Nitin Goyal 2018-05-08 09:13:45 UTC

This is the scenario where it is failing.

N1-r        N2-r        N3-s
#100gb-d    #100gb-d    #100gb-s
#100gb-d    #100gb-d    #100gb-s
#100gb-d    #100gb-d    #100gb-s

N stans for node
# stands for device
d stands for arbiter disabled
s stands for arbiter supported

1. Give the required tag to first and second node.
# heketi-cli node settags node_id arbiter:required

2. Give the disable tag on drives of first node and drives of second node.
# heketi-cli device settags node_id arbiter:disabled

3. Give supported tag on third node and its devices.
# heketi-cli node settags node_id arbiter:supported
# heketi-cli devices settags node_id arbiter:supported

4. Create volume.
# heketi-cli volume create --size=100  --gluster-volume-options='user.heketi.arbiter true'

5. Try to create 10 volumes atleast.

6. Check that it is actually working according to tags.
# heketi-cli topology info
# gluster v info

pretty much a duplicate of BZ #1575899.

Should be fixed by https://github.com/heketi/heketi/pull/1172
and subsequent fixes (https://github.com/heketi/heketi/pull/1182 ...).

Comment 7 John Mulligan 2018-05-29 17:25:16 UTC

As Michael noted this is nearly but not exactly a duplicate of bug #1575899. Thus it should have the same status and be tested along with that bug.
