Sigh..sorry to hear that. If you have another non-btrfs partition with plenty free space, you could try: fallocate -l 32GiB /path/swapfile (more/less depending on disk space) mkswap /path/swapfile swapon /path/swapfile and try the btrfsck again. It really should not use that much RAM.. :( If that's not an option either I'f afraid I don't know anything else to try. -h
