Hi All,
Currently gluster management in ovirt is not complete if disks in hosts are not
formatted/mounted. It expects those actions done prior in the host added to
ovirt. We have a requirement to manage physical disks by
1. identify and populate physical disks.
2. identify and manage hardware raids.
3. create thick and thin logical volumes in unused physical disks.
4. format and mount logical volumes.
5. fstab management for new logical volumes.
To have this feature, I would like to start a discussion here to explore
possible options suitable for vdsm/engine.
We have done a small PoC with OpenLMI[1] by having verbs in vdsm to achieve
this. Also we explored ovirt-engine directly calling tog-pegasus/cim-server to
get cim object to avoid two level of hopes ("ovirt-engine calls vdsm <-> vdsm
calls openlmi locally <-> openlmi does the job" than "ovirt-engine calls vdsm
<-> openlmi does the job") which also works.
I would like to get your feedback about the PoC and suggestions/ideas how
physical disk management can be.
Regards,
Bala
