Cloned from launchpad blueprint


Utility ramdisk is a ramdisk that is used by Ironic to perform maintenance of bare metal nodes.

The features it provides include:

– Firmware upgrades
– Hardware configuration
   – Setting up a RAID array
   – Turning on or off virtualisation features
   – Configuring iSCISI devices
– Volume management
   – Disk partitioning
   – Secure disk erasing

Utility ramdisk does not provide its own API due to overcomplexity of building such a disk. Instead the ramdisk polls an API endpoint provided by Ironic to get new tasks for a specific node and for reporting progress.

Ironic should be able to interrupt tasks. However, there is a subset of tasks, e.g., firmware upgrade, that should not be interruptible.
