sqlite3.OperationalError: disk I/O error

[loraine-gueguen]

Do you get error "sqlite3.OperationalError: disk I/O error" when the askomics volume is stored on the NFS filesystem ?

I have this error when the volume is stored on the NFS file system in the askomics, celery_askomics, celerybeat_askomics services :
- ../../../finalresult/phaeoaskomics_docker-data/askomics:/tmp/askomics

In docker inspect flaskomics-docker-compose_standalone-askomics-1 output:

        "Mounts": [
            {
                "Type": "bind",
                "Source": "/shared/projects/phaeoaskomics/finalresult/phaeoaskomics_docker_data/askomics",
                "Destination": "/tmp/askomics",
                "Mode": "rw",
                "RW": true,
                "Propagation": "rprivate"
            }
        ],

And:

$ stat -f -c %T /shared/projects/phaeoaskomics/finalresult/phaeoaskomics_docker_data/askomics
nfs

The error does not happen when the volume is stored locally:
- /tmp/askomics:/tmp/askomics

$ stat -f -c %T /tmp/askomics
ext2/ext3

In docker inspect flaskomics-docker-compose_standalone-askomics-1 output:

        "Mounts": [
            {
                "Type": "bind",
                "Source": "/tmp/askomics",
                "Destination": "/tmp/askomics",
                "Mode": "rw",
                "RW": true,
                "Propagation": "rprivate"
            }
        ],

Works fine as well with a named volume stored in /var/lib/docker/volumes.
