The Logical Volume Manager (LVM) is a subsystem for online disk storage management which has become a de facto standard for storage management under Linux.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
This release supports Linux 2.4.0-test10 and 2.2.17. New Features include persistent snapshots for logical volumes, the ability to resize snapshot logical volumes, a new API to request the usage rate of a snapshot logical volume, integration with VFS to consistently mount ReiserFS filesystems on snapshots (VFS patch necessary), support for Physical Volume and Volume Group UUID, lv*(8) commands which now use the Default Volume Group specified in the environment variable LVM_VG_NAME, a /proc/lvm directory hierarchy for use in parsing VGDA information, and, last but not least, initial support for DEVFS.
This is a major update despite the fact that it is tagged as beta, as it provides fixes for a page lock bug, an lvchange activation/deactivation bug, a chunk size bug in lvcreate, a PE size bug in vgcreate, synchronization problems with snapshot lists, and a segfault in vgexport. Also, a new sort algorithm is now used in pv_read_all_pv_ol_vg.c to correct ordering problems.
