Parity Check does not include a day of month

[masterwishx]

how i can setup check parity in Unraid - '0 0 1 */3 *' every 3 month on 1 day 0:00?

if i set custom i can select months , but no day of month select , only weeks :

i can manually add (0 0 1 */3 *) to parity-check.cron , but not shure it will work it not shown right in webGUI ...

You can specify the day and the which week in the month.

This runs on the 4th Sunday in the month.

Yes, but can't set 1day of month every 3 months.

If I set Sunday of first week, but in first week no Sunday this month? For example month starting at Friday at 1day... Can I set manually (0 0 1 */3 *) in parity-check. cron? Strange that this option not available in WebGUI.

You should be able to edit.

root@computenode:~# cat /boot/config/plugins/dynamix/parity-check.cron

Generated parity check schedule:

0 0 * 1,4,7,10 0 [[ $(date +%e) -le 7 ]] && /usr/local/sbin/mdcmd check NOCORRECT &> /dev/null || :

and then run update_cron. But not sure how it will show in gui.

I tryed (0 0 1 */3 *) it shows like every 1day of every month... you think (0 0 1 */3 *) this will not work? If it use cron at all. I need use your example?

[SimonFair]

No it was just a example of the format.

So you could create /boot/config/plugins/dynamix/custom-parity-check.cron

0 0 1 */3 * /usr/local/sbin/mdcmd check &> /dev/null

once created run update_cron

It should put this entry into /etc/cron.d/root
