Hi,

Maybe unrelated to the problem that you have just now, but it is not 
recommended by SQLite developers to use SQLite databases from network drives. 
See for example 
https://stackoverflow.com/questions/788517/sqlite-over-a-network-share/27457688.

The risk of corrupting the database should not be so big if Geoserver just 
reads the GPKG database and Geoserver is the only user, but poor performance 
that is also mentioned is not what you want. If the GPKG database is not huge 
if might be just better to copy it into local disk.

That said, I do sometimes read GPKG databases through http connection over the 
net with GDAL and its vsicurl mechanism and is does work quite well. So you are 
free to play with Samba but you are warned.

Maybe some troubles with locking could be avoided if Geoserver opened the 
connection to SQLite as read-only. I am not sure if it happens already or if is 
configurable. It might be a safe and useful option also with local files.

You sent the message through the geoserver-security mailing list. Thank you for 
your responsibility but I do not see any security risk with just this issue and 
I think that geoserver-users list is good place to continue the discussion.

Aihe: geoserver gpkg on samba share issue

Hi,
Does someone have experience with GPKG stored on samba share and problem with 
creating Store on GS?
I have GS on apache tomcat on Linux Red Hat, and samba shared store remotely on 
different network, mounted on tomcat user (as GS is running with that user).
There is no problem creating store from Linux host, but there is an error on 
mounted samba share: “Unable to obtain connection: [SQLITE_IOERR]  Some kind of 
disk I/O error occurred (disk I/O error)”.
Does anyone have a clue what is problem?
Best regards,
Miroslav Hrcan
