[ale] initramfs capable of a multi-device btrfs / new initramfs with dracut help?

[Michael Trausch]

You would configure the array in mdadm.conf (either in /etc/mdadm.conf or
/etc/mdadm/mdadm.conf) and the use mdadm to start up the array, for example:

ARRAY /dev/md0 level=raid6 metadata=1.1 num-devices=5
UUID=3b4045f1:253f01cd:de8
023f1:8438c90d name=fennel:ATS_SRVR_R6_0

And:

mdadm --assemble /dev/md0 --uuid=3b4045f1:253f01cd:de8023f1:8438c90d
