[ovirt-users] Hosted Engine Spamming Transition E-Mails

[Charles Tassell]

Hi Didi,

   Unfortunately the box got reinstalled before I could grab the logs.  
I think I have an idea as to what caused the issue though. When I was 
originally registering the oVirt node one of the fiber channel volumes 
wouldn't detect so it just kept waiting to register with the hosted 
engine, saying it couldn't connect to the storage pool.  I rebooted the 
host which caused the FC volume to show up and it looked like everything 
was fine.  We were able to host VMs on the box but then it started 
spitting out the error E-Mails.  I migrated the VMs off to other hosts 
(2 went fine, 2 went into a paused state citing storage error) and then 
rebooted the host.  When the host rebooted I shutdown the VDSM service 
and started it manually from the shell prompt.  I'm not sure if it was 
right when the box came up or when I started VDSM manually, but that 
messed up our storage pool and crashed all the VMs in the cluster, 
putting them into a paused state.

   Sorry I couldn't grab the logs, one of the other techs had some spare 
time so he reinstalled the OS the same afternoon.
