Hi, basically the aggregate free space is relevant, as you mentioned you
are having thin volumes, right?

Hi Ladislav,
Thank you for the reply.
On the matter of your Recommendation, when you mention free space,
were you referring to:
* Space that is free/unallocated on the Aggregate, allowing the
AutoGrow
* Or all that is allocated to the volume but not actual Data Space
Kindly awaiting your reply.

Hi,
for the NetApp part, here is copy-paste from the netapp kb:
Answer
The volume "Over Provisioned Space" value provided in OnCommand
System Manager (OCSM) is the "Over Provisioned Size" field provided
by the |volume show|
<https://docs.netapp.com/ontap-9/topic/com.netapp.doc.dot-cm-cmpr-930/volume__show.html>
at the cluster shell.
This value is determined by the following formula:
(volume size) - (volume used) - (volume space available) - (snapshot used
space) == storage that can't be provided by the aggregate if written to the
volume
for the ovirt part:
Ovirt will see the volume size available within thin-volume without
any knowledge of the aggregate space (available/or not) in behind.
Recommendation:
on netapp side do volume auto-grow and you are safe as long as you
have free space inside aggregate.

*Subject: *oVirt and Netapp question
Dear oVirt,
Few months ago our production environment oVirt with main Shared
storage via NFS Netapp is live.
We have been deploying VMs with thin provisioned HDD 40GB based
template, CentOS 7.
The Netapp NFS v4 storage volume is 7TB in size, also Thin
Provisioned.
First attached screenshot shows the space allocation of the
production volume from Netapp side.
Is there anyone in oVirt community who would be able to tell me
the meaning of the 5.31 TB Over Provisioned Space?
<image001.png>
Second attached is the info of the production volume from oVirt
side:
<image002.png>
What I want to understand is the way how is oVirt reading the
volume usage and Netapp and where is the difference.
Is the Over Allocated Space something that is just logically
used/reserved and will be intelligently re-allocated/re-used as
the actual Data Space Used grows or am I looking at oVIrt
actually hitting Critical Space Action Blocker and will have to
resize the volume?
If there is anyone from Netapp or with good Netapp experience
that is able to help understanding the data above better, thank
you in advance?
Kindly awaiting your reply.
