Firstly I changed the sets and disk detection section in dmraid.py as dmraid
-tay in disklist and setlist didn't seem to work on my system (although I was
using a later DMRaid revision than that supplied with FC3 as stock so that
may be the cause)?
I also had to change the makeDevInode function in isys.py as anaconda gave
errors relating to symlinks already existing.
Bear in mind the changes I made may not be the best way of handling the
errors/issues as I'm no Python programmer but they worked for me. I've
attached two text files containing the functions changed from Mark's original
patch.
Note the dmraid.py changes are using a hardcoded pdc string in the re.match
function for my promise controller. This will need changing for other
flavours of ataraid controllers.
