Calibre contentserver external SSD

[rbodewes]

I cannot "get" books via web interface on KOBO Aura H2O (firmware 4.20.14601) from calibre-64bit-4.12.0 on SSD card when internal memory of KOBO is full. KOBO (PLUS) books are stored on SSD (when memory is full) and books sent to external memory via Calibre USB connection is possible, and those book are "recognized" by KOBO reader. This was also the case with previous versions of Calibre and KOBO.
Can this be solved at server side? or
is it necessary to change the " LocalStorage" at KOBO side?
A solution with a fixed storage location (external!) would be sufficient

No, the server has no way to specify where books are downloaded by the browser on a client device.

If you are using the browser to download books, then, as Kovid said, it is the firmware on the device deciding where the book is downloaded to. The download location defaults to the root directory of the main storage. I would have expected it to download to the SD card when the main storage is full, but, the definition of "full" could be the problem. Kobo tries to keep somewhere between 100 and 200MB free for firmware updates and start putting books downloaded from the store onto the card at about 100MB full. I don't know the exact numbers. These come from questions to Kobo and some experiments I did a few years ago. And they might have changed.

If this did happen with a previous firmware, it could be a deliberate change or a bug. As they haven't sold devices with external SD cards for a while, it wouldn't surprise me if this was something they dropped or missed in testing. I would suggest reporting the problem to Kobo. And, do you know what the last firmware version it was where it did work? That would help in the report, and knowing that, it might suggest whether it is deliberate or not. And I'd be curious to test it.

Another thing you can do is ask about a patch in the Kobo forum. There might already be one, or it could be easy to add.
