What advantages does it have over ODS or > VM? Filesystems can share partitions. For instance, /usr and /var can be separate filesystems, but share the same storage. This is great for things like quotas. You can add and remove partitions to the storage pool as needed. Plus, AdvFS is journalled, and supports ACLs. AdvFS is the filesystem, it isn't a volume manager. DEC also uses LVM for handling the storage partitions themselves. Of course the lines between the filesystem and the volume manager are getting very blurry. > Much as I like FreeBSD, Sun is the way to go for large disk farms. Perhaps for the server itself, but Sun storage arrays seem very overpriced (ie A5000 series). > -- > Roger Marquis > Roble Systems Consulting > http://www.roble.com/ > Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
