zfs discuss - Dec 2008 - Degraded zpool without any kind of alert

I just saw by luck that one of my zpool is degraded!:

$ zpool list
NAME    SIZE   USED  AVAIL    CAP  HEALTH  ALTROOT
home   97,5G   773M  96,7G     0%  ONLINE  -
rpool  10,6G  7,78G  2,85G    73%  DEGRADED  -

It would be nice if gnome could notify me automatically when one of my zpools
are degraded or if any kind of ZFS error occurs.
It should be possible. I know that in Ubuntu they have included a mechanism to
create manually notify messages on the desktop, like the "update
notification" messages.

I would also accept if it could be possible at least to send automatically a
mail when a zpool is degraded.

Could it be possible to implement for the next release a ZFS monitoring or alert
mechanism?

Yes.  It is a weird failing of Solaris to have an advanced fault 
detection system without a useful reporting mechanism.

This the script (run as root via crontab) I use to have an email sent 
to ''root'' if a fault is detected.  It has already reported a
fault:

#!/bin/sh
REPORT=/tmp/faultreport.txt
SYSTEM=$1
rm -f $REPORT
/usr/sbin/fmadm faulty 2>&1 > $REPORT
if test -s $REPORT
then
   /usr/ucb/Mail -s "$SYSTEM Fault Alert" root < $REPORT
fi
rm -f $REPORT

I do much the same thing, although I had to fiddle it a bit to exclude a 
certain report type. A while ago, a server here started to send out 
errors from:

Fault class : defect.sunos.eft.undiagnosable_problem

The guys on the fault-discuss list have been unable to enlighten me as 
to the problem, and I''m ashamed to say I have not taken any steps. 
Except to replace the entire machine, I have no idea what to try.

I just wanted to note that although the fault detection is very good, it 
isn''t always possible to work out what the fault really is.
