[hobbit] hobbitclient, disk and AIX

[Deiss, Mark]

How is a mount of a CD-ROM/DVD drive handled? You may want to exclude those
entries too - unless you have don't care about those pesky 100% always full
reports on /dev/cdrom mounted to whatever...

Just a follow up on my own thread...

I've had a look at how BB resolves this issue.  They grep the df output for
lines that begin with /dev.

This will work fine for me as all my LV's (logical volumes), whether
locally attached SCSI disks or fibre attached FAStT SAN disks, follow this
convention... which is kind of obvious seeing as i never noticed any
problems with the BB client! ;-)

Can anyone else confirm that all AIX systems will follow this
convention?  I'm relatively new to AIX and only run 5.2 and 5.3.  I
therefore feel I'm not qualified to categorically state that all local
filesystems will be created on logical volumes.  Does AIX actually enfore
the use of LVM?

At this point, I've made the following change to my copies of
hobbitclient-aix.sh

df -Ik | sed ...
  *becomes*
df -Ik | grep '^/dev' | sed...

Would anyone have objections to getting the source updated to match by
Henrik?

This would obviously become a bit redundant :-)
