raid automatic resync... where is the command?

[François Patte]

Bonjour,

I installed f40 with raid1 partitions.

Every sunday an automatic program resync the partitions and a lot of 
programs "pedal in the sauerkraut" (french idiom) because of this 
automatic resync...

I have looked in cron.d directory, cron.weekly, and other cron program 
in order to disable this resync which lasts for hours as soon as you 
have high terabit disks.

How can I disable this? (And what could the issue?)

Thank you.
