Source: linux Severity: important Hi,
OpenStack Cinder is capable of doing block storage multi-attach. This means that a single block device can be attached to multiple VMs. Of course, this is only possible for filesystems that supports it. Currently, this means ocfs2 (from Oracle) or GFS2 (from Red Hat). I suppose that it's possible other cloud providers (AWS, Azure, Google?) may also support multi-attach? I don't know them enough to be sure. But at least, I'm sure it is useful for OpenStack. So, please enable: CONFIG_OCFS2_FS and CONFIG_GFS2_FS in the generic-cloud images as they are useful in the context of cloud images. Cheers, Thomas Goirand (zigo)
