To all those confused, my apologies. Here's an excerpt from the user guide (included in the distribution). You can find the software on ftp://ftp.lemis.com/pub/vinum/vinum-0.01.tar.gz. Be warned that it's still pretty flaky. Vinum is a logical volume manager modeled after the Veri- tas(R) volume manager. It is not a clone of Veritas, howev- er, and attempts to solve a number of problems more elegant- ly than Veritas. It also offers features that Veritas does not have. This guide explains how to install and configure Vinum on a FreeBSD system. See also the technical notes and the man pages Vinum(4) and Vinum(8). Concepts ________ As used in this document, a volume manager is a software component which isolates file systems from the underlying disk hardware. Instead of building file systems on disk partitions, they are built on volumes. This has a number of advantages: o Volumes may span disk drives. o Volumes may be larger than any drive. o By spreading the disk load over multiple volumes, it is possible to improve performance. o By dynamically increasing the size of a volume, it is pos- sible to solve space problems without repartitioning. o By replicating data within the volume, it is possible to improve availability. o By changing the volume configuration on-line, it is possi- ble to reorganize disk storage on-line. -- See complete headers for address and phone numbers finger grog@lemis.com for PGP public key To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
