Hi Lon, the original idea of scanning /dev was not too bad but after porting it to ocfs2-tools and brainstorming again with the guys, we found a few things that could be done better. Let's change a direct scan of /dev into: - scan /sys/block first for well.. block devices. - sysfs exports enough info for us to filter out removable devices like cdroms that we don't care to even check and to gather maj/min of each device. - scan /dev only to match maj/min and gather the device name. - never dig or attempt to check hidden files. Please review or apply. Joel: once applied on top, this is basically the same code that would land in ocfs2-tools. Thanks Fabio -- I'm going to make him an offer he can't refuse.
