Hi devs,
while btrfs is now declared as stable ;-) i wanted to retest btrfs on
our production cluster on 2 out of 54 osds. So if they crash it doesn't
hurt.
While if those OSDs run XFS have spikes of 20MB/s every 4-7s. The same
OSDs after formatting them with btrfs have spikes of 190MB/s every 4-7s.
Why does just another filesystem raises the disk load by a factor of 10?
I'm running dumpling.
