Still running 3.10-3-rpi alas because there isn't a 3.14.15 :) version of the pi kernel yet, but is an increasing latency as the uptime increases, expected?
What parameters did you use for mkfs.btrfs? What are your fstab mount options? Does btrfs detect non-spinning media, i.e. use the SSD options automatically?
grep btr /etc/fstab /dev/mmcblk0p2 / btrfs defaults,relatime,ssd_spread,discard,space_cache,autodefrag,inode_cache,compress 0 1 grep btr /proc/mounts /dev/mmcblk0p2 / btrfs rw,relatime,compress=zlib,ssd_spread,discard,space_cache,autodefrag,inode_cache 0 0
Lost the commandline history around the conversion, but I believe it was just btrfs-convert /dev/mmcblk0p2 Tried to rebalance and/or defrag once after the conversion, but kernel 3.10 kernel panics. /sys/block/mmcblk0/queue/rotational = 0 Where/what package is mount.btrfs's manpage in debian? No idea whether btrfs has actually detected it's not spinning. -- Tim Connors
