FWIW, on a 4 x 8TB ZFS RaidZ1, I run a ZFS scrub every night at 2:30am.
if I had more disks in a raidz2 (equiv to raid6) then I might do it weekly
rather than daily, but since a raidz1 is only singly redundant, I figure
daily scrubs increases the chance I'll catch a failing drive sooner than
than

Hi,
is it required to run /usr/sbin/raid-check once per week? Centos 7 does
this. Maybe it's sufficient to run it monthly? IIRC Debian did it monthly.
I just checked on Fedora 32. It does not run raid-check at all, at least not
via a cron entry. /usr/sbin/raid-check is available, though.
