Out of curiosity, who here schedules automatic xfs_fsr runs, and with what frequency? Currently I just run it manually now and then when performance starts to seem sluggish.
I run it daily during the week, at a time when load is practically nil, on two boxes with 24TB storage each, divided into six parts of about 4GB. A 10-pass xfs_fsr run usually completes in under one hour, except on monday, when it takes three to four hours.
I don't have any stats on the net effect, though. Regards, roel
