Between LVM2 v2_02_178-rc1 and LVM2 v2_02_177, there will not be any components/features remove, except include some bug fixes, right? Thanks a lot.

Yes there will be. We've had no bug reports for the -rc, so the final release will be the same as the -rc. > 2) For the next LVM2 version, which components will be affected? since I saw > that clvmd related code has been removed. We've decided to bump the version number to 3.0.0 for the release *after* 2.02.178. This change in version number indicates the *start* of some large changes to lvm. Obviously the release notes for v3.0.0 will go into this more. But, initially the most visible changes will be removal of a couple of features: clvmd - The locking required to provide this feature was quite pervasive and was restricting the adding of new features (for instance, I'd like to be able to allocate from any LV not just PVs). With Dave Teigland's lvmlockd I think the vast majority of use cases are covered. Those that are wedded to clvmd can continue to use LVM2.02.* Also, testing cluster software is terribly expensive, we just don't have the resources to provide two solutions. lvmapi -- This library has been deprecated for a while in favour of the dbus api. - Joe ___ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
