Not with iscsi directly,
I have 4T of SATA/SAS raid1 arrays and scrubbing takes very close to 2/hr per T. So if you have 12 2T drives (not sure how many arrays you have), but presuming you are using all 2T per array, that's going to take 4 hr/per array.
Hi David, it is just one array, RAID6, about 20Tb. It takes forever - maybe also because the system is under load. So the scrubbing is paused, then resumed the next night at 01:05. It took us quite some time to figure out what was happening. Our iscsi clients are timing out all over the place -
There is a good article on the Arch wiki on it https://wiki.archlinux.org/title/RAID#RAID_Maintenance
I think I have seen that, but what I am missing is a way to de-prioritize the scrubbing. -- Per Jessen, Zürich (-0.2°C)
