Description Nikolai Sednev 2015-03-22 12:26:42 UTC 
Description of problem:
Impossible to turn RHEVH host to global maintenance via CLI, in HE environment, which blocks the RHEVM upgrade for engine that's running on top of RHEVH host.  

[root@alma03 ~]# hosted-engine --set-maintenance --mode=global

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


How reproducible:
100%

Steps to Reproduce:
1.Deploy HE on RHEVH and try to put the host in to the global maintenance mode.
2.
3.

Actual results:
IOError: [Errno 30] Read-only file system: '/var/lib/ovirt-hosted-engine-ha/ha.conf'

Expected results:
Global and local maintenance have to be available for RHEVH.

Additional info:
You might consider moving required config files to TMP for maintenance to be possible.
Comment 1 Fabian Deutsch 2015-03-26 13:23:48 UTC 
This looks like a persistence bug on node, taking it over.
Comment 2 Ying Cui 2015-03-31 12:06:17 UTC 
This bug need zstream clone. Thanks.
Comment 4 Nikolai Sednev 2015-09-07 14:32:24 UTC 
Hi Fabian,
Please provide relevant RHEVH7.2-HE image link, so this bug could be verified.
Currently we don't have required RHEVH-HE image, which also 3.6 compatible.
Comment 6 wanghui 2015-11-12 03:33:35 UTC 
Test version:
rhev-hypervisor7-7.2-20151104.0.iso
ovirt-node-3.6.0-0.20.20151103git3d3779a.el7ev.noarch
ovirt-node-plugin-hosted-engine-0.3.0-2.el7ev.noarch

Test steps:
1. Configure hosted engine succeed
2. Click <Set Hosted Engine maintenance> to setup global mode

Test result:
1. The "global" level can be setup succeed.

So this issue is fixed in ovirt-node-plugin-hosted-engine-0.3.0-2.el7ev.noarch.
