It manages disks and can find it's drive properly if they changed devices - that's working relay fine that I was able to remove nearly all wire configurations for drives and I'm eaven run a volume with only one single drive plex - just to get this feature. It can (or should be able to) resize a volume and should inform the system about. I have some ideas about how to get FFS resizeable without needing to freeze or umount it before and without loosing inodes. Vinum is the frontend for managing the size of the volume and it should inform the fs driver about any change, because there is no need to manualy call an additional tool. My point is modifying FFS but that's the same for any fs. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
