Hosted-engine.conf on host2 that I am trying to add back contains only hostid and ca path: ca_cert=/etc/pki/vdsm/libvirt-spice/ca-cert.pem host_id=2 Can someone help me how to check if there is DB or Storage corruption? Would it be dectructive or risky to try to populate the hosted-engine.conf of host 2 with missing values? Any advices? ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic@activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

I was able to get the other hosts to forget about this one, by running hosted-engine –clean-metadate –host-id=2 Now I would like to try to add the host back to HE pool, but I have a question: “Is there a time I should wait, between cleaning metadata and re-adding the host?” Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic@activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

If they are not, most likely there is some corruption somewhere - in the engine db or shared storage. You might want to skim this for a general rather-low-level overview: https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ovi... Do you see no errors on your other hosts? In -ha logs? Please also note that 4.3 is EOL. The deploy process was completely rewritten in 4.4 (in ansible, previous was python), although should in principle behave similarly - so if your data is corrupted, upgrade to 4.4 probably won't fix it. Good luck and best regards, -- Didi
