When trying to build a RAID1 on main fs. After normal debian stretch
install :
<code>
root@server:/home/nous# btrfs device add /dev/sdb1 /
root@server:/home/nous# btrfs fi show
Label: none uuid: ef0b9dad-c0eb-4a3b-9b41-e5e249363abc

*** Some devices missing
</code>
Some IO errors on /dev/sda are found in journalctl (see them below)
I cannot believe that /dev/sda has no hard disk errors when installing
without problems, but has many ones when I "btrfs device add /dev/sdb1 /".
I can reproduce the problem : reinstall (3times...) and try "btrfs
device add /dev/sdb1 /" with the same results...
