"In computer storage <http://en.wikipedia.org/wiki/Computer_storage>, *logical volume management* or *LVM* provides a method of allocating space on mass-storage <http://en.wikipedia.org/wiki/Mass_storage> devices that is more flexible than conventional partitioning <http://en.wikipedia.org/wiki/Partition_%28computing%29> schemes. In particular, a volume manager can concatenate, stripe <http://en.wikipedia.org/wiki/Data_striping> together or otherwise combine partitions into larger virtual ones that administrators can re-size or move, potentially without interrupting system use." _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
