Hi all, I am using CKPT V19, when I tried to test the checkpoint, there was a error: 1) using checkpoint_self, error message is: "not container initckpt: Invalid argument", FAILED; 2) using external checkpoint, there are two situations, if I did it like this a) $ ./test & [1] 3493 $ echo 3493 > /cgroup/0/tasks" --------------------> FAILED, error message is "echo: write error: Device or resource busy" b) $ ./loop & $./checkpoint 3493 >loop.ckpt --------------------->FAILED, error message is "checkpoint: Device or resource busy (you may use 'ckptinfo -e' for more info)" I do not know what is wrong, Thank you very much..
