3. It seems /paiInternal/storage.ext4 not created. How do I solve it ? Please help me.

The "/" directory still has 100G+ Avail.

6. I found the reason and solved it. But openpai data probability won't be saved any more in storage.ext4
   Maybe the docker container "openpai/internal-storage-create" volume is not create correctly.
   I get into the container "openpai/internal-storage-create" , manually run "touch storage/READY" in /paiInternal , then this error is OK, like this below:
