Thread: Server crashes with a long BTRFS error list

    Server crashes with a long BTRFS error list

    Suddenly I receive an error with the bellow dump when the SLES 12.4 started. Then, the system becomes unavailable.

    When I repair the root filesystem [on a guest VM otherwise it isn't possible because the root filesystem is mounted] then the root partition is marked as full even an empty space is shown in df.

    What happened, how can I solve it? The very strange thing is that when I restore a 3 weeks old backup [where all was OK ] into a new VM I receive the same error messages.
