Hi All,

Last November, I shared a shell script that helped me keep track of the specific hot-swap drives I had in the various slots of my servers.  Although encouraged by Roman and John, I declined to make a project out of it.

I've since kicked it around some more, and thought a bit about supporting more than just the SCSI subsystem.  The latest and greatest is still built around some standard executables:  blkid, lspci, lsusb, sginfo, and smartctl.  The original was similar to "lsscsi", but with controller details and device serial numbers.

New features:
       Supports non-SCSI storage devices
       Describes layered block devices
               MD raid
               LVM
               generic device mapper
               loop (partial)
       Shows UUIDs
       Shows mountpoints
       Avoids repeating subtrees when enumerating raid devices

I struggled with the last item, until I gave up on bash.  I needed to pass data to subroutines by reference, and bash is sorely lacking in that area.  The new script is in python.  I'm releasing this one under the GPL version 2.

Please give it a whirl.

Awesome, however:

$ ./lsdrv.py
  File "./lsdrv.py", line 301
    print "%s  └─Volume Group %s (%s) %s free {%s}" % (indent,
vg.name, ','.join([dev.name for dev in vg.PVs]), vg.free, vg.uuid)
                                                      ^
SyntaxError: invalid syntax

Maybe it's a copy-paste thing from my mail that does it. Could you put
it somewhere, like a pastebin?

Yeah, should have thought of that first.

HTH,
