balance start -dprofiles=raid0,convert=single,vrange=0..580000000000000 fails given lots of space. Looking at the paths of the failed block groups via btrfs inspect-internal logical-resolve, I see they are 7 largish files, from 4G-133GB in size. So looks like the profile conversion code hit's a snag in this case. I'm in the process of mv the files away, and will try it again after to see if it works. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
