I followed Anton's idea but didn't see any difference.
My tests were repetitive PostMark runs, and each run was different. For
instance, I didn't let PostMark delete the files once it finished, deleted the
odd numbered ones by hand, put the rest in a different directory, re-run

Randomly select and remove 500,000 of those files.
Repeat (a) creating files, and (b) randomly removing files, until your file
system is full enough for your test, or you run out of time.
That's a pretty
Hello all.
I'm doing a course project to evaluate recovery time of RAID-Z.
One of my tests is to examine the impact of aging on recovery speed.
I've used PostMark to stress the file-system but I didn't observe any
noticeable slowdown.
Is there a better way to "age" a ZFS file-system?
Does ZFS
