Hi all,

Recently on this list it was discussed it is a good practice to perform data scrubbing for some raid levels.
Can someone advise what raid levels need that operation scheduled on a regular basis? Perhaps all raid arrays that have:

/sys/block/md*/md/sync_action

[sync_action] property?

For example is it good for raid1 array?

Cheers,
- -Nik
