Bug #28247
Set the default value of scrub delay to 4 and resilver delay to 2
Description
With the addition of the sequential scrub/resilver code, vfs.zfs.scrub_delay and vfs.zfs.resilver_delay default to zero. Normally, these default to a scrub delay of 4 and a resilver delay of 2. These delays effectively limit the maximum IOPS that can be used by a scrub or resilver, leaving some capacity available for normal use of the system.
The standard defaults of 4 for scrub and 2 for resilver should be restored.

This needs review, and the PR needs to be merged in.

This is indeed not merged to 11.1-stable. Do you have any suspicions about it?
#7
Updated by Sean Fagan almost 3 years ago
No, it's a trivial change, but it still affect behaviuor and should be reviewed and QA'd.

QA'd -- sure. What's for review, I don't see a pull request, otherwise I'd say it looks good to me.
