you have still 4GB free of non RAID-1 (single) space, which is currently unavailable, but it is planned that BTRFS will support mixed storage: some files can be RAID-1, some files can be RAID-0 and rest is basic (single) storage > > Fabian-- > To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in > the body of a message to [email protected] > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
