Subject: notification about corrupt files from "btrfs scrub" in cron
Date: Wed, 22 Nov 2017 21:54:10 +0200	[thread overview]
Message-ID: <1511380450.1675.94.camel@gmail.com> (raw)

Hello,

I have following cron job to scrub entire root filesystem (total ca.
7.2TB and 2.3TB of them used) once a week:
/bin/btrfs scrub start -r / > /dev/null

Such scrubbing takes ca. 2 hours. How should I get notified that a
corrupt file was discovered? Does this command return some error code
back to cron so it can send an email as usual? Will cron wait 2 hours to
get that code?

I tried that command once without "> /dev/null" but got no email
notification about the results (eventhough the check was OK) - why?

Thank you.
