creation of a simple file based volume driver in nova/volume/driver.py #533

Open termie opened 13 years ago

termie commented 13 years ago

I think we need the possibility to also save volumes on mounted NFS exports (or some other stuff locally mounted).

I tried to create a simple file based volume driver, creating new images with qemu-img and removing them with rm. Is this sufficient? At the moment I think only check_for_setup_error() is missing, I'll add this soon (checking for the existence of qemu-img and checking if the given mountpoint is mounted and is writable by nova).

Please give me some feedback and more ideas...

Imported from Launchpad using lp2gh.

(by vishvananda) Nova-volume will attach locally if the export is on the same host as the instance you are trying to attach to.

(by berendt) I think per default the VolumeDriver() is used. VolumeDriver() uses LVM2 and creates new volumes in a VG, per default nova-volumes.

(by ttx) @Christian: still working on that ? Or should we unassign you and let someone else have a shot at it ?
