Hi All,
If i read this correct, and one would have a heavily fragmented zpool ( doesn't
matter if it's the rpool , or the data pool), and wanted to defrag , provided
you have mirrors, remove the mirrored disks, remove the partition on it, and
read it...
After that is done resilvering, do the same for the other disks....
No, I suspect I was wrong. I have seen a performance gain after
resilvering, but I don't currently understand where it comes from. I'll
need to do some investigating, and see if I can reproduce it with
spacemap histograms.
