scheduled scrubs never run

[Bobo Moreno]

hi,

I've had FreeNAS for several versions, on 9.10 now. I can't figure out why my scrubs don't run, I have to run them manually once in a while.

attaching pic of setup, they never run and I've waited more than 14 days several times; I've also deleted and recreated the schedule many times. Never ever runs, even when it is over the threshold.

as far as I know these things are run via cron, but when I check crontab for root (assume it's root?) there's nothing.

sudo crontab -u root -l
crontab: no crontab for root

what can I check to see what's wrong??

Hmmm... try setting the 'Threshold days' to 10, with scrubs scheduled for specific days of the month. This approach works for me (I use the 12th and 26th, you could use whatever dates you prefer):

FWIW, on my system the relevant scrub entry in /etc/crontab is:

Code:

00   01   12,26   *   *   root   PATH="/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:/root/bin" /usr/local/libexec/nas/scrub -t 10 tank

Scrubs work fine, so it's a configuration error.

Scrubs will run if the current date/time has been selected AND it's been more than threshold days. Not OR, AND.

Scrubs will run if the current date/time has been selected AND it's been more than threshold days. Not OR, AND.

...and the threshold days are counted from the time the last scrub finished, not when it started.

@Bobo Moreno, what's the output of 'zpool status' on your system?
