Description of problem: Long story short (1). Single host self hosted engine test setup. One of the drives in a RAID6 died, somehow taking the host off-line. Replaced the drive, restarted the host, broker and agent refused to start due to corrupted meta data file. With the help of Yedidyah Bar David I managed to clear the meta data file (2) and return the host to normal.

Hi Gilboa and Didi, I looked into the manual HE metadata cleanup and I am wondering if it is not a better option to use the existing hosted-engine --clean-metadata verb? ~~~ # hosted-engine --clean_metadata --host-id=52 ~~~ Also, are you truly having 52 hosts to support your single HE VM? I hope not. It is not recommended to use more than few hosts that can provide High Availability for your Hosted Engine VM. It is unnecessary complication of things.
Ok, I see now this newer thread: https://lists.ovirt.org/archives/list/users@ovirt.org/message/DXPXGU4FKWJOJZJM7CKAB7ZJZFR7NJZE/.
As you can see (in the ML thread) --clean_metadata failed. I had to manually clean the meta-data file. - Gilboa
Thanks, yeah, I read that later.
