I am attempting to use a Raspberry Pi to run Calibre-server and access calibre libraries stored on a Drobo on the local network.
I mounted the drobo on the Pi
***********
MAKE MOUNT DIRECTORY ON Pi
mkdir drobomnt
sudo mount //192.168.0.9/public /drobomnt
**************
I can then see all the files on the Drobo.

When I run
calibre-server --with-library /drobomnt/CalLibtest --port 8081 &

it comes up with this error
**********************************
pi@raspberrypi ~ $ Traceback (most recent call last):

OperationalError: attempt to write a readonly database

[1]+ Exit 1 calibre-server --with-library /drobomnt/CalLibtest --port 8081
******************

However, I can run the server when the files are directly attached to the Pi.
(apart from a library which has 17000 entries)

It is , I think, a problem with the Drobo.

Anyone got any ideas?
