Re: [ovirt-users] VM HostedEngie is down. Exist message: internal error Failed to acquire lock error -243

I just blocked connection to storage for testing, but on result I had this error: "Failed to acquire lock error -243", so I added it in reproduce steps. If you know another steps to reproduce this error, without blocking connection to storage it also can be wonderful if you can provide them.

Exist message: internal error Failed to acquire lock error -243 I just ran a few extra tests, I had a 2 host, hosted-engine running for a day. They both had a score of 2400. Migrated the VM through the UI multiple times, all worked fine. I then added the third host, and that's when it all fell to pieces. Other two hosts have a score of 0 now. I'm also curious, in the BZ there's a note about: where engine-vm block connection to storage domain(via iptables -I INPUT -s sd_ip -j DROP) What's the purpose for that?
