hi selmf, thanks for your advice.

I have mounted the NAS on the raspberry (with ip 192.168.0.21)

sudo mkdir /mnt/MyComics
sudo mount -t cifs -o username=mylogin,password=mypassword //192.168.0.21/MyComics /mnt/MyComics

and created the library (extremely slow!)
sudo YACReaderLibraryServer create-library MyComics /mnt/MyComics

The created .yacreaderlibrary in /mnt/MyComics is owned by root (because of sudo?) and need to be changed to pi:pi to the server to work

Still having the errors while creating library (using libunarr):
- rar.c:65: Skipping directory entry "Comics X"
- zip.c:104: Skipping directory entry "Comics Y"
- rar.c:98: Skipping newsub header @115887447

for mostly each comics

But anyway it seams to work

Many thanks for the help i will make more tests, but think that the issues mainly come from rights.

These errors are info messages generated by libunarr. Zip and rar archives contain multiple data entries. If the entry is a file, it will get extracted, if it is a directory, there strictly speaking is no data to be extracted. It's just additional info how the data in the archive is structured, but has no data that is extractable. Think of it as a label. So you need to skip those entries when extracting. The newsub header is similiar. No need to worry about it.

Yes, the Raspberry Pi, even the latest version, is a slow device. Plus, you are creating the library over the network, the network is going to be a huge bottleneck.

My suggestion is to create the libraries using YACReaderLibrary in a Mac or PC with the HD attached using SATA or USB. After that, once the HD is back in your NAS or the Raspberry Pi, you can use the add-library command. Updates shouldn't be so problematic, just do them frequently with small batches of comics.

Hi Luis,

I tried to compile with p7zip library on Raspberry.

But when launching YACLibraryServer, I got the error:
QIODevice::read: device not open

or
Processing comicsQSqlDatabase: QSQLITE driver not loaded
QSqlDatabase: available drivers:

why such errors?
Thanks for your patience.
