Configuring zpool scrub frequency and viewing history

[wayfarerdev]

Hello,

Where can I configure the frequency for scrubs of the zpools on my Proxmox server? Also, where is the history of previous scrub attempts logged?

Thank you.

zpool status -v should tell you when the scrub was run the last time. The cronjob "/etc/cron.d/zfsutils-linux" will trigger the scrub every second sunday of a month at 0:24 in case you didn't set up anything else yourself.

@Dunuin Thank you very much.

Is it safe to edit /etc/cron.d/zfsutils-linux to change the interval? I wonder if a pve upgrade might change it back or similar.

As for other packages, APT is going to detect the changes, stop and ask you how do you want to handle it (replace the file, let it alone, merge the diffs).

I would just add another cronjob instead of edit that file, if you want the scrub to run more frequently. Once a month is not that bad though.
