ubiquity crashes when installing to btrfs array

[Simon Davy]

Installing to a pre created/scanned btrfs whole disk array crashes

Created with

sudo mkfs.btrfs -L raid0 -m raid1 -d raid0 /dev/sd{c,d,e,f}

/dev/sdc is chosen as /, not formated

Only other specified partion was /boot on completely different drive, sda1

Filesystem mounted and populated fine, but crashes towards the end of the process, 2 times same crash now.

Am going to try again with partitions, not whole disk.

Same problem with whole disk partitions.

Gonna try installing to one disk and rebalancing after install

FWIW, installing to single btrfs disk, and then rebalancing/converting to RAID, worked fine.
