This looks correct if this is in the [irs] section of the configuration. [irs] # Together with volume_utilization_chunk_mb, set the minimal free # space before a thin provisioned block volume is extended. Use lower # values to extend earlier. # volume_utilization_percent = 50 # Size of extension chunk in megabytes, and together with # volume_utilization_percent, set the free space limit. Use higher # values to extend in bigger chunks. # volume_utilization_chunk_mb = 1024 To get the correct configuration format, you can do: python /usr/lib/python2.7/site-packages/vdsm/config.py > > > > in /etc/vdsm/vdsm.conf on every Host > > > > But the Initial Size of the Disk is always 1GB and then increments to 2GB Please share the vdsm.conf file with these settings. > > > > 4GB would be the maximum Size I need before I destroy the VM. So if the > initial Size would be 4GB the pausing shouldn’t happen anymore The initial volume size is always 1GiB, regardless of these settings. After creating 1GiB lv, we extend the lv volume_utilization_chunk_mb megabytes. So your setting will result in 1GiB lv, and after you write about 150MiB, it will be extended to 5GiB. So I guess that you want to use volume_utilization_chunk_mb = 3072 Which will give you 4GiB lv after the first extend. We support initialSize argument when creating volumes - use when importing external vms (v2v), but it is not exposed in the ui. If you think think exposing it in the ui is a useful feature, you can file a bug: https://bugzilla.redhat.com/enter_bug.cgi?product=ovirt-engine Nir _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
