Fixed my problem. While looking through /var/log/syslog, I noticed this line around the same time swap mount failed.
BTRFS warning (device sda3): swapfile must not be copy-on-write Then a few lines later... systemd[1]: swap.img.swap: Failed with result 'exit-code'. systemd[1]: Failed to activate swap /swap.img. systemd[1]: Dependency failed for Swap. systemd[1]: swap.target: Job swap.target/start failed with result 'dependency'. Yes my root is on btrfs and I did not see this error before. So I deleted /swap.img and started over. $ sudo rm -rf /swap.img $ sudo touch /swap.img $ sudo chattr +C /swap.img $ sudo fallocate -l 2G /swap.img $ sudo chmod 600 /swap.img $ sudo mkswap /swap.img $ sudo swapon /swap.img No error and "swapon --show" gives this: NAME TYPE SIZE USED PRIO /swap.img file 2G 0B -2 Just what I was expecting. So problem solved for me, maybe a check can be put in to see if it's on btrfs and apply the 'chattr +C' option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1788321 Title: swapon failed: invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1788321/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
