Yesterday I announced the availability of the first alpha release of vinum, but neglected to say what it was. 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
