zfs discuss - Oct 2006 - ZFS Automatic Device Error Notification?

Okay, so now that I''m planning to build my NAS using ZFS, I now need to
devise or learn of a preexisting method to receive notification of ZFS handled
errors on a remote machine.

For example, if a disk fails and I don''t regularly login or SSH into
the ZFS server, I''d like an email or some other notification
immediately of the ZFS event.

Are there already ways to do this?  

A few leads into what existing technologies or few keywords on what to look for
would help.  I''ve found the FMA references with SMF, but that
doesn''t seem to be the full answer to my quest here.

It''s been awhile since I''ve used the web-console to ZFS,
perhaps this is now a feature there?  If not, that would be a great addition!

Thanks for any leads or tips!

I use the smartmontools smartd daemon to email me when disk drives are
about to fail. If you are interested in configuring smartd to send
email notifications prior to a disk failing, check out the following

Thanks for the feedback Ryan, I''ll certainly consider this option.  

However, the ideal solution would also have the option send a notification at
X-interval (daily), and at least let you know the monitoring is working and that
there are no errors, and could also provide specific ZFS pool status update.

There are several ways to do this.  Two of the most popular are syslog
and SNMP.  syslog works, just like it always did (or didn''t).  For more
details on FMA and how it works with SNMP traps, see the conversations on
the OpenSolaris fault management community,
	http://www.opensolaris.org/os/community/fm/

and Keith wrote an interesting blog about FMA-SNMP

In short, ZFS doesn''t invent anything new for such notification, it
just
uses the existing methods.

Thanks Richard, this seems to be exactly what I was looking for.
