# CoronaFS
|
|
|
|
CoronaFS is PhotonCloud's mutable VM-volume layer.
|
|
|
|
Current implementation:
|
|
|
|
- custom block backend, not NFS
|
|
- control API on `coronafs-server`
|
|
- raw volume data stored under `/var/lib/coronafs/volumes`
|
|
- exported to workers as `nbd://` targets via `qemu-nbd`
|
|
- primary consumer: `plasmavmc` managed VM volumes
|
|
|
|
Intentional split:
|
|
|
|
- mutable VM volumes live on CoronaFS
|
|
- immutable VM images live in LightningStor object storage
|
|
|
|
This keeps VM root/data disks on a shared block path while leaving image distribution on the object layer.
