[ILUG] disk failure (and advance warning)

[John P. Looney]

 I've a few boxes that I don't want to go down.

 But disks die, so likely they will at some stage.

 To avoid this, I'd love to be able to have something email me when the
S.M.A.R.T software detects disk problems. But, data like:

 Is a little....useless, without context. Is there any software out there
for reading this in & deciding how close a disk is to failure, or are you
better off just running: 

barney:/home/john# smartctl  -c /dev/hda
Device: ST39111A  Supports ATA Version 4
Drive supports S.M.A.R.T. and is enabled
Check S.M.A.R.T. Passed.

 And grepping for "Passed" ?
