[Evms-announce] EVMS Release 1.9.1 (beta)

The EVMS team is announcing the second beta-level release of the new 
Enterprise Volume Management System. Package 1.9.1 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 1.9.1 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 1.9.1 is supported on the 2.4.20 and 2.5.63 kernels. Users have reported 
successfully running on earlier 2.4 kernels as well.

Remaining issues:

- Clustering
The clustering capabilities are still undergoing integration and testing. 
Initial instructions for installing EVMS in an HA cluster environment have 
been included in this release, but the full details of failover and remote 
administration are still being worked out.

- Snapshot
The EVMS snapshot plugin has now been ported to use Device-Mapper. It has 
only undergone limited testing thus far, so be gentle. Since the 
Device-Mapper snapshot support is only included for the 2.4 kernels, 
snapshots will not work under 2.5. Also, the metadata format has changed in 
order to be compatible with Device-Mapper, so existing EVMS snapshots from 
1.2.1 or earlier will not be recognized by 1.9.1. Please delete your old 
snapshots before running the new EVMS. Also, snapshot rollback has been 
temporarily disabled. This functionality was implemented in the EVMS kernel 
driver in 1.2.x, and will need to be reimplemented in user-space.

- Move
Support for "moving/replacing" objects in DriveLinking has been added. Move 
support for the MD/Software-RAID plugin will be added soon. As with 1.9.0, 
all move operations must be performed offline. Online move will be added 
after the 2.0 release.

- New Text-Mode UI
The new ncurses UI is very close to complete. The vast majority of operations 
now work in the new ncurses, and only a small subset of the GUI functionality 
still needs to be added. The previous text-mode UI is still included, but 
does is not built by default.

- Root on EVMS
We are still working on instructions and/or scripts to enable users to have 
their root filesystem on an EVMS volume, using an init ramdisk or initramfs. 
At this time, if you have your root filesystem on an EVMS volume, please 
continue to use the 1.2.1 release. However, there have been reports from 
users who have sucessfully created initrd's that work with EVMS 1.9.0 and 
allow them to mount their root filesystem through EVMS.

Please send any questions, problem reports or bugs to the EVMS mailing list:
