Schedule Long SMART on the first Saturday of every month

[maesonc]

As the title says, I’m trying to schedule Long SMART Tests on the first Saturday of every month. However, it doesn’t seem like I’m able to set the desired cron schedule using the TueNAS SCALE Web UI.

I’m wondering if it’s a limitation of cron itself. I’ve read that there are newer versions of cron out there that can do the following with #. For example:

“At 02:00 on the first Saturday of the month.”
0 2 * * 6#1 

This doesn’t work on The SCALE UI though.

Would you guys recommend setting up the cron via the CLI?

Any advice appreciated!

Days “1-7” instead of “*”?

Yup tried it but its being handled as an ‘OR’ condition - so it runs on the first 7 days and every Saturday after.

Woah, didn’t we already have this discussion.

Periodic Snapshots and cron setting

Hello! I have been searching for an answer, but found none. I’d like to set a cron job (or for that matter scheduled task) to run snapshots on every first sunday of the month. I have found no option to set task described (via GUI or config files) way, nor any new entry in cron files or new timer files in systemd. Are there any other locations/files to set the schedule? Best regards, Łukasz

@stux I remembered the same and was just about to do the search and say the same thing myself.

I guess this is a reminder for us all to put in the effort and search for an existing answer rather than transferring the effort onto others by asking the same question yet again.

Apologies for not looking hard enough. Thanks @Stux and @Protopia - will refer to the other thread then.

Altho it’s the same core issue… you should at least comment on the feature request or add a similar one for your case (smart)

I just explained how you can apply the workarounds from that superuser discussion in TrueNAS:

FEATURE REQUEST: Advanced cron settings for periodic snapshots

The superuser link are just workarounds to check either the day of week or the “first N-day of month” condition in the executed code itself. Of course you can do that in TrueNAS - that needs to go into the command field. Like with every cron implementation. Example: (TN CORE) [Bildschirmfoto 2024-06-21 um 13.39.56] Replace the echo "It's the first Saturday!" part with the real command you want to run. HTH, Patrick

course you can do that in TrueNAS - that

So any way to execute the code first saturday only of every month?
0 0 1-7 ** doesn’t work will execute every day from 1 to 7 of every month
0 0 1-7 * Sat will execute like above and every saturday
0 0 */100,1-7 * sat will run first day of every month doesn’t matter if its sunday, monday,…
