[Engine-devel] Storage Device Management in VDSM and oVirt

[Shireesh Anjal]

Hi all,

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 Logical Volumes (LVs)
     - Create, resize, delete, partition, format and mount 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
