nagios check_smartmon fails with SATA presented as SCSI devices

4 Comments / Nagios, Open Source / By /

I’ve been using Nagios for a while. I use it to monitor many things, varying from disk space to disk temperature. One of the packages I use for this is net-mgmt/nagios-check_smartmon. This code is getting out of date it seems. According to the timestamp at the top of the file, the last time it was updated was 2006-03-24 10:30:20.

Here’s how I fixed that, but first, I took snapshots,

But more data has been added to it. So I take another snapshot, and send that: Send what’s accumulated since previous send # zfs snapshot storage/compressed/bacula@2013.07.25:08:20 And now I send the incremental stream: # zfs
