[Evms-announce] EVMS Release 1.9.2 (beta)

The EVMS team is announcing the third beta-level release of the new 
Enterprise Volume Management System. Package 1.9.2 is now available for 
download at the project web site: http://www.sf.net/projects/evms

This beta release is for the new EVMS design, which is based on user-space 
volume discovery and communication with existing kernel drivers, such as 
MD/Software-RAID and Device-Mapper.

As of this release, much of EVMS has stabilized and has undergone significant 
testing. However, certain parts of the project are still undergoing testing 
or development (see the list of outstanding issues below). Please continue to 
use caution when using this release. We greatly appreciate any testing, 
feedback and comments from our users about your experiences with the new 
design.

Please see the INSTALL file in the 1.9.2 package for information about 
installing and getting started with the new EVMS. Since this new design is 
based on user-space discovery, there will no longer be boot-time volume 
activation. Please see the INSTALL file for information about how to activate 
your volumes using the EVMS user-interfaces.

EVMS 1.9.2 is supported on the 2.4.20 and 2.5.64 kernels. Users have reported 
successfully running on earlier 2.4 kernels as well.

Remaining issues:

- Clustering
The HA clustering components are undergoing testing of various failover and 
remote-administration scenarios, and documentation about using the clustering 
components is still being added to the Users Guide. Also, a new clustering 
plugin has been included, for use with RSCT clusters. This plugin is still 
very experimental, and must be built separately in the plugins/rsct/ 
directory in the 1.9.2 package.

- Snapshot
As with the 1.9.1 release, snapshots created using the EVMS 1.x releases will 
not work with the new EVMS design, due to a metadata format change. Please 
delete your snapshots from 1.x before using 1.9.x. Snapshot rollback is still 
disabled. Device-Mapper support for snapshots is only included for the 2.4 
kernels. Snapshots will not work on 2.5 kernels.

- Root on EVMS
Instructions are now available for creating an init-ramdisk image for use 
with EVMS. Please see the INSTALL.initrd file in the 1.9.2 package. These 
instructions have been tested on 2.4 kernels. They have not yet been tested 
on 2.5 kernels. However, init-ramdisks should work similarly on 2.4 and 2.5.
