Not sure as I have not played with EVMS. I know Gregory has. As I
understand it EVMS is an LVM implementation from IBM. I believe it is
more of an integrated set of tools in that it not only resizes the block
device but will automatically call the appropriate filesystem tools to
resize the fs also.
When I last tried EVMS, it had hooks for automatically running the appropriate resize tool for various filesystems. EVMS also had the very nice ability to re-export "normal" partitions as EVMS partitions, which then let you do things like concatenate them or take snapshots of them. I.e., if you have /dev/hda2 as / and later add EVMS, you can optionally use /dev/evms/hda2 instead, and then do things like snapshots of it, without having to repartition/format/install as you would with LVM/LVM2.
The EVMS guys have gone back to the drawing board to refactor a lot of stuff back into user-space. Haven't heard much about it since.
I think they're too busy rewriting everything for 2.6. :)
