Okay, again, thank > you for your time!!! Travis, IBM Germany coded a multipath extension for LVM1 which got included in the SuSE distribution (not supported by Sistina). You should be able to get patches from them. Because Sistina offers LVM2/device-mapper (L)GPLed which gets all new features added, we discontinued to add any new features to LVM1 about a year ago. We _do_ support LVM1 (bug fixes, user support). We are close to the LVM2.0 release which will be LVM1 feature compatible. Multipathing (or redundant paths) is a planned 2.2 feature. > > Cheers, > Travis > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
