Hi;
I have been playing with this. The userspace tools are not backwards compatible. (2.4 tools didnt seem compatible with 2.2 tools either-- Ive got 3 sets of them laying around) Currently, LVM2 under 2.5 repeatedly will hit a BUG() and oops for me. I also managed to destroy a test striped lv. I wouldnt trust any important data to it yet. (Jens Axboe has expressed a willingness to help with the problem. Just a matter of time...) You need a > 2.5.47 kernel (eg. a recent bk snapshot, or eg. 2.5.47-ac2 or 2.5.45-mcp2) to even compile with DM support if you want to play with this.
