Sqlite3 apparently doesn’t like my new NAS setup. Reads are fine but writes were not working and regardless of the timeout I give it was failing with database is locked error.

Error I get:

python3.9/site-packages/peewee.py", line 3221, in execute_sql                                        cursor.execute(sql, params or () 
sqlite3.OperationalError: database is locked

I had to play with pragmas a bit. At the end what worked is

sqlite3 mydatabase.db

# Write ahead logging: 
# https://www.sqlite.org/pragma.html#pragma_journal_mode
PRAGMA journal_mode=WAL;

# Made this to normal from full.
# https://www.sqlite.org/pragma.html#pragma_synchronous
PRAGMA synchronous=normal;

You can obviously use DB Browser sqlite UI:

If this doesn’t work either, unmount the network drive and mount it like this with nobrl option which prevents byte range locking but this comes with disadvantage of likelihood of database corruptions

sudo mount -t cifs //192.168.1.100/MY_SHARE_NAME /mnt/MY_MOUNT_FOLDER -o username=my_user,password=my_pass,uid=$(id -u),gid=$(id -g),nobrl
