Goodnight everyone, I am new on this and I'm trying to mount a Plex Server on my Raspberry Pi 3 + for Movies, Series, etc.
I recently bought a pen drive for multimedia storage and I am trying to configure it for the Plex storage folder in the RasPi 3+, but before I had another one of smaller capacity as a test, which worked well, and in a day of troubles I had to remove it forcedly, because I could not unmount it from the terminal or from the omv web gui, therefore it was in a "lost" state... in short, at this moment I try to place the new pen drive as plex storage, and the web interface throws me the following message:
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; omv-mkconf plexmediaserver 2>&1' with exit code '1': chown: cannot access '/srv/dev-disk-by-label-Kingston/plexmediaserver': No such file or directory
(The previous pen drive was "Kingston", and i can't set it to the new one)
Error #0:

Can you help me to set it properly? Let me clarify that I know just a little about Linux, but I try to learn a little more just to handle this well.
As my first Thread on this forum, please forgive me if I'm breaking some rules. 
Thanks.
