Comment 1 Nir Soffer 2021-05-19 09:58:59 UTC
We should document the configuration on vdsm side based on:
https://github.com/oVirt/vdsm/blob/master/doc/thin-provisioning.md#configuration

The documentation should:
- explain how disks are extended using the default configuration
- explain how to tune the configuration to avoid pausing vms when
  using fast storage

Comment 2 RHEL Program Management 2021-05-19 09:58:59 UTC
The documentation text flag should only be set after 'doc text' field is provided. Please provide the documentation text and set the flag to '?' again.

Comment 4 Sandro Bonazzola 2023-08-03 07:17:31 UTC
No updates in the last 2 years, closing as won't fix.
If still relevant please open an issue on https://github.com/oVirt/ovirt-site/issues
