sqlite3.OperationalError: database is locked

情景描述

windows上代码文件，设置为共享目录，mount到linux使用。运行python manage.py migrate，出现错误

报错

 [root@localhost sqlalchemy]# python manage.py db migrate /root/py_env/coacs/lib/python3.6/site-packages/flask_sqlalchemy/__init__.py:794: FSADeprecationWarning: SQLALCHEMY_TRACK_MODIFICATIONS adds significant overhead and will be disabled by default in the future.  Set it to True or False to suppress this warning.   'SQLALCHEMY_TRACK_MODIFICATIONS adds significant overhead and ' INFO  [alembic.runtime.migration] Context impl SQLiteImpl.

原因

sqlite3与smb的lock冲突

解决

mount -t cifs //192.168.1.121/coacs /opt/coacs -o username=username,password=password,nobrl
nobrl 表示不向服务器发送对 byte range lock 的请求。
