Subject: RAID5 doesn't mount on boot, but you can afterwards?

Hi All,

A RAID5 setup on raw devices doesn't want to automount on boot. After I skip 
mounting I can log in (Ubuntu server 14.04 on kernel 4.1.8) and just do a 
"sudo mount -a" to get all mounted fine. So the array doesn't seem to be 
broken. "btrfs fi show /data" doesn't show anything wrong either.

The only weird thing I see in the syslog is :

BTRFS info (device sdd): disk space caching is enabled
BTRFS: has skinny extents
BTRFS: failed to read the system array on sdd
BTRFS: open_ctree failed
 
If I reboot the machine the drive in the log changed and looks random (i've 
seen in 3 boots sda, sdc and sde passing by)

I am using btrfs-progs 4.2.1 if that matters in this case...

Anyone have a clue whyt it's not automounting? Or something I can do to 
troubleshoot?

Thanks in advance.

Cheers,
Sjoerd
