Here's my hack-y fact that adds facts for mounted partitions on linux w/ disk used, available, and total as well as a fact for all available mounts.

--- begin ---
mounts = []
mntpoints=`mount -t ext2,ext3,ext4,reiserfs,xfs`
mntpoints.split(/\n/).each do |m|
mount = m.split(/ /)[2]
mounts << mount
end
Facter.add("mounts") do
confine :kernel => :linux
setcode do
mounts.join(',')
end
end
mounts.each do |mount|
output = %x{df #{mount}}
output.each do |str|
dsk_size = nil
dsk_used = nil
dsk_avail = nil
if str =~ /^\S+\s+([0-9]+)\s+([0-9]+)\s+([0-9]+)\s+/
dsk_size = $1
dsk_used = $2
dsk_avail = $3
Facter.add("mount_#{mount}_size") do
setcode do
dsk_size
end
end
Facter.add("mount_#{mount}_used") do
setcode do
dsk_used
end
end
Facter.add("mount_#{mount}_avail") do
setcode do
dsk_avail
end
end
end
end
end
