I think that you are mixing up a lot of different things and to be honest I am not sure what configuration you have and what exactly you are trying to do.<br>
so lets try to simplify it?<br>
what type of storage are you working on?<br>
which host is the spm?<div><br>

hello,<br>
<br>
I am in trouble<br>
<br>
I have 3 servers dedicated to test OVIRT:<br>
01- engine + vdsm (8 cpus, 32GB ram , 2TB HD)<br>
02 - vdsm (8 cpus, 32GB ram , 2TB HD)<br>
03 - vdsm (8 cpus, 32GB ram , 2TB HD)<br>
<br>
I want to create cloned virtual machines but in my configuration I can only save virtual machines on server 01; my configuration refers a DATA DOMAIN on server 01<br>
<br>
All my virtual machines are : 2 cpu , 6 GB ram , 500gb HD and were created like CLONE<br>
<br>
My server 01 is the data domain and all new virtual machine is created, via NFS, on server 01 , who has 2TB maximum capacity ( the same size of partition /sda3 = 2TB)<br>
<br>
how can I save each virtual machine on a desired vdsm server ?<br>
<br>
What I want is :<br>
server 01 - engine + vdsm : 03 virtual machines running and hosted phisicaly on this host<br>
server 02 - vdsm : 04 virtual machines running and hosted phisicaly on this host<br>
server 03 - vdsm : 04 virtual machines running and hosted phisicaly on this host<br>
<br>
but I have this :<br>
server 01 - engine + vdsm : 03 virtual machines running and hosted phisicaly on this host<br>
server 02 - vdsm : 01 virtual machines running on this server BUT hosted phisicaly on server 01<br>
server 03 - vdsm : none, because my DATA DOMAIN IS FULL (2TB )<br>
<br>
How to solve this problem ?<br>
is it possible create one DATA DOMAIN for each VDSM host ? I think this is the solution but I do not know how to point VMs to be saved on specific data domain.<br>
<br>
thanks<br>
<br>
<br>

<br>
if you plan to overcommit then go with thin. The drawback is that<br>
if you of course hit the physical limit the VMs will run out of<br>
space...<br>
if you plan to allocate 500GB each, consume all of it, never plan<br>
to grow then go with the "clone"….yes, it's going to take time to<br>
write all that stuff. With "thin" you need to do the same amount<br>
of writes, but gradually over time while you're allocating it it<br>
<br>
hope it helps<br>
<br>
Thanks,<br>
