[ovirt-devel] Recovering from power failure

Hi, Well, there is a severe bug that I complained about it on 4.2 (or 4.1? I don't remember) and it's regarding "yanking the power cable". Basically I'm performing a simple test: kill all hosts immediately to simulate a power loss without UPS. For this test I have 2 nodes, and 4 storage domains: hosted_storage (that was setup during the HE installation), 1 iSCSI domain, 1 NAS domain and 1 ISO domain. After all the nodes loose power, I power them on and the following procedure happens: 1. The node with HE finishes booting, and it takes few minutes until the HE is up. 2. When the HE is up, all the storage domains comes back to life as online and VM's with high availability starting to boot. 3. Few minutes later, *all* (with the exception of hosted_storage) storage domains are going down 4. After about 5 minutes, all the other storage domains which went down, are coming up, but by then, and VM's without high availability that are not hosted on hosted_storage remains down, you'll need to power them manually back. This whole procedure takes about 15-25 minutes after booting the nodes, and this issue is always repeatable, just kill the power to the nodes, power them up again and see for yourself. The solution would be to change the code and if a storage domain is up - *leave it up*, skip the check.
