Hi,
Did you follow 
https://www.ovirt.org/develop/troubleshooting-nfs-storage-issues.html ?
In general those are several aspects that would prevent ovengine from writing 
to the directory and in addition to checking it manually
you can use nfs-check.py described over there.

I think the fact that your NFS is over Ceph should be something that is 
'abstracted away' or you might ask yourself - how NFS share implemented by Ceph 
is different from any other NFS share?

BR,
Konstantin

Hi,


I am trying to perform a self hosted ovirt cluster. All goes well and towards 
the end the setup fails at the task


'Initialize lockspace volume'


with the following error message:

The underlying storage is NFS on top of Ceph (which is not listed in the ovirt 
documentation). Does this ring any bell to anybody?


Please let me know if you need more information in this regard or contents from 
any of the log files.


Thanks
