Hi list,

(I do have a backup)

I am running

- Linux deck 4.0.3-1-ARCH #1 PREEMPT Thu May 14 01:08:37 MDT 2015 armv5tel
- btrfs-progs v4.0

I want to scrub the following file system

btrfs filesystem df /pools/dataPool
Data, RAID10: total=666.00GiB, used=663.88GiB
System, RAID10: total=64.00MiB, used=80.00KiB
Metadata, RAID10: total=2.00GiB, used=1.11GiB
GlobalReserve, single: total=380.00MiB, used=68.00KiB

btrfs filesystem show /pools/dataPool
Label: 'dataPool'  uuid: b5f082e2-2ce0-4f91-b54b-c2d26185a635
        Total devices 4 FS bytes used 665.00GiB
        devid    2 size 931.51GiB used 334.03GiB path /dev/sdb
        devid    4 size 931.51GiB used 334.03GiB path /dev/sde

and get lots of what is shown in the next paragraph. What might be the reason? 
Could it be a hardware error on my server? Is this at all connected to btrfs?

Thank you very much.
