Re: [ovirt-users] Unable to Delete a VM snapshot . (Juan Hern?ndez)

18 May 2015

      Hi  Juan Hern?ndez  ,
RE:Unable to Delete a VM snapshot .

Do you mean that there is no unique identifier for a VM snapshot.?

The only way out is from my java client ,I have to take care of creating a snapshot with unique description.
SO that I can delete/restore  a snapshot based on the unique description.

Thanks,
Prashanth R

Hello Didi,
this is a clean install of the first host. (I am trying a disaster scenario and will later restore the backup)

Subject: [ovirt-users] HE setup failing: Cannot set temporary password 
for console connection
Hello,
a week ago I set up a HE (3.5.2) with no problems; now this fails.
You mean you re-deploy the same host (clean setup), or adding another host?
...
I
suspect storage trouble but cannot pinpoint it. Did someth. change 
there with the recent async release?
The storage domain is NFS3 via a 1G link to a ZFS storage appliance. 
The export is working quite fast; tested with iozone running for over 
24h without problems.
It starts with the "Verifying sanlock lockspace initialization" phase; 
which lasts about 7min (!).
In the end it seems sanlock is locking the domain down. I can only get 
it back by stopping sanlock and vdsm.
Attached is the full vdsm lock.
Thanks!
