btrfs raid10 setups cause the hardware reset to happen very frequently. I have a eSATA enclosue (SansDigital) that has two eSATA ports and contains 2 banks of 4 drives. 4 per eSATA port (port multiplier). I encounter no problems when using RAID1 with BTRFS across 8 drives. However, when I use the btrfs balance start -dconvert=raid10 -mconvert=raid10 to convert the set of 8 drives from a RAID1 to a RAID10, it all falls apart with SATA hardware resets. I am guessing that the btrfs driver sits above all this and that the error is in the SATA code and not the btrfs code which relies on it.
