Overwrite policy

Before OpenLMI-Storage overwrites or deletes a device, it first checks if the device is unused.

Unused device:

• Is not mounted.
• Is not part of running device, e.g. MD RAID, Volume Group or LUKS.

If a device is used, any operation which would overwrite or delete it returns CIM_Error with error message “Device XYZ is mounted” or “Device XYZ is used by ABC”. It is up to the application to first unmount the device, close the LUKS/dm-crypt device, stop the RAID or remove it from running Volume Group etc.
