You can find them here http://www.cs.wisc.edu/~michaelc/block/dm/rhel4/ I am not pushing either approach right now since one is a crazy ugly hack (u3-bio-sense/) that I do not want to maintain or try to completely test for something like RHEL. The other possibility (u3-blkerr) is nicer but needs to be fixed up for some cases and needs lots of testing. The latter approach is also a little hacky since I had to work around the KABI restrictions but I do not think it is as evil as the u3-bio-sense approach.
