Hi a= ll,

As part of adding Gluster support in ovirt, we need to introduce some Storage Device management capabilities (on the host). Since these are quite generic and not specific to Gluster as such, we think it might be useful to add it as a core vdsm and oVirt feature. At a high level, this involves following:

- A "Storage Devices" sub-tab on "Host" entity, displaying information about all the storage devices*
- Listing of different types of storage devices of a host
    - Regular Disks and Partitions*
    - LVM*
    - Software RAID*
- Various actions related to device configuration
    - Partition disks*
    - Format and mount disks / partitions*
    - Create, resize and delete LVM Volume Groups (VGs)
    - Create, resize, delete, format and mount LVM Log= ical Volumes (LVs)
    - Create, resize, delete, partition, format and mo= unt Software RAID devices
- Edit properties of the devices
- UI can be modeled similar to the system-config-lvm tool

The items marked with (*) in above list are urgently required for the Gluster feature, and will be developed first.

Comments / inputs welcome.

Thanks,
Shireesh

Anything we can share with rtslib ( http://ww= w.risingtidesystems.com/doc/rtslib/html/) which is the API behind targetcli which is the CLI for LIO (linux-iscsi.org) target, which is in Linux kernel now) ?
They have some VERY basic LV and VG handling.
