Dear All,
I have been using ovirt for a long time with three hypervisors and an external engine running in a centos vm .

This three hypervisors have HBAs and access to fiber channel storage. Until recently I used version 3.5, then I reinstalled everything from scratch and now I have 4.2.

Before formatting everything, I detach the storage data domani (FC) with the virtual machines and reimported it to the new 4.2 and all went well. In
this domain there were virtual machines with and without snapshots.

Now I have two problems. The first is that if I try to delete a snapshot the process is not end successful and remains hanging and the second problem is that
in one case I lost the virtual machine !!!

Not sure that I fully understand the scneario.'

How was the virtual machine got lost if you only tried to delete a snapshot?

So I need your help to kill the three running zombie tasks because with taskcleaner.sh I can't do anything and then I need to know how I can delete the old snapshots
made with the 3.5 without losing other data or without having new processes that terminate correctly.

If you want some log files please let me know.

Hi Enrico,

Can you please attach the engine and VDSM logs

Thank you so much.
Best Regards
Enrico
