Re: [CentOS] mdadm raid-check

[John Pierce]

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 later
