Description of problem:-
While updating the RHEVH host from RHEV-M GUI if its failed then error message in the imgbase logs is not clear.
Imgbase logs are giving traceback error in the update logs but the error message is generic and not providing much detailed information about why update got failed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. If RHVH upgrade get failed then
2. Reboot and login NGN
subprocess.CalledProcessError: Command '['lvcreate', '--thin', '--virtualsize', '4367354880B', '--name', 'rhvh-4.0-0.20170307.0', u'rhvh/pool00']' returned non-zero exit status 5
It should give a detailed error message in imgbase logs.
imgbased already logs detailed information in /tmp/imgbased.log or /var/log/imgbased.log, depending on the version.
Are you expecting this to appear in RHVM, or just the stderr in the logs?
'imgbase check' should not be creating LVs.
upgrade to rhvh-18.104.22.168-0.20180531.0
upgrade failed due to no enough space
stderr be captured in `imgbased.log`
