I went ahead and reinstalled wont with FC14 – I probably could have done a:
[root@wont ~]#Â yum install btrfs-progs [root@wont ~]#Â modprobe btrfs [root@wont ~]#Â mkfs.btrfs -L VMstordev /dev/sdb /dev/sdc /dev/sdd [root@wont ~]#Â mount /dev/sdb /kanigix
The hardest thing was getting the /etc/fstab correct because of the need to probe for devices after boot time:
/dev/sdb /kanigix btrfs defaults,device=/dev/sdb,device=/dev/sdc,device=/dev/sdd 0 1
