I've tried a few things.
I can run fsck.reiserfs successfully with out error. I can mount it read only. The three pvs don't have any free extents left so I tried adding a fouth pv and growing the lv and filesytem by 1Gb in oder to see if it would mount then, but it still froze. I tried to use pvmove to move one or two extents off the th other pvs onto the new one, but I couldn't figure out the syntax on how to move just one or two extents. I don't even now if that would work.
I'm guessing it's an lvm problem, though I suppose it could be reiserfs or md problem instead.
Any help or suggestions you might have would be greatly appreciated.
