[ovirt-users] oVirt Gluster Hyperconverged problem

[Hanson]

Hi Guys,

I encountered an unfortunate circumstance today. Possibly an achillies 
heel.

I have three hypervisors, HV1, HV2, HV3, all running gluster for hosted 
engine support. Individually they all pointed to HV1:/hosted_engine with 
backupvol=HV2,HV3...

HV1 lost its bootsector, which was discovered upon a reboot. This had 
zero impact, as designed, on the VM's.

However, now that HV1 is down, how does one go about replacing the 
original HV? The backup servers point to HV1, and you cannot readd the 
HV through the GUI, and the CLI will not readd it as it's already 
there... you cannot remove it as it is down in the GUI...

Pointing the other HV's to their own storage may make sense for multiple 
instances of the hosted_engine, however it's nice that the gluster 
volumes are replicated and that one VM can be relaunched when a HV error 
is detected. It's also consuming less resources.


What's the procedure to replace the original VM?
