I updated my OpenSUSE system today. After rebooting, I could not log in, even as root from a tty. The system gave a lot of errors about journald so I figured I would boot up a rescue disk and see what I could find.
In rescue mode, I mounted the hard disk's root logical volume on /mnt. Did a 'cd /mnt' and poked around. But any time I try to change anything, mkdir, rm, touch, etc., nothing happens and I don't get the prompt back.
I can log in from another tty, but running 'kill -9' on the original process (touch or whatever) doesn't kill the process. I can kill the bash process and get a login prompt back, but the 'touch' or whatever process is still there.
Running 'mount' shows: /dev/mapper/system-root on /mnt type btrfs (rw,relatime,space_cache,subvolid=259,subvol=/@/.snapshots/1/snapshot).
How can I make changes in the volume?
