Quick Start Guide for Installing JRiver Mediacenter 27 on an rPi4 2-4-8GB

<< < (13/14) > >>

Wheaten:
if you need to re-install sometime, just activate VNC server via raspi-config. There is no need to start it from a SSH session. Guess that's why the VNC server opts for the :1, as user pi is already connected through SSH. the ":1" indicates a screen number.

I have the Raspi booting from an SSD just fine but I just changed the external USB drive with the music files from a hard drive to an SSD drive and copied the music files from my Mac to the SSD.

Previously the external hard drive worked OK with Raspi.   Now, the SSD is read only and as a newcomer to Linux, changing read/write permissions on the drive seems more complicated than I think it should be.

Is there an easy fix for this?

Wheaten:
You should never have copied the files with a MAC, without taking care of owner and rights.
As I have no clue, how you did the copy or even which file system you used, it's an educated guess for me.

I should start with, having the user pi take ownership:

--- Code: ---sudo chown pi:pi -R <path to mount>
--- End code ---

Next some trial and error, validate by each step if you have R/W access.

--- Code: ---sudo chmod -R 744 <path to mount>
--- End code ---
When fail:

--- Code: ---sudo chmod -R 774 <path to mount>
--- End code ---
When fail:

--- Code: ---sudo chmod -R 777 <path to mount>
--- End code ---

I'll hope this will work, but I would advise to partition the disk on the Pi box and perform the copy on this box.
As it might be that the UNIX and LINUX rights will give you all kind of conflicts.

Thanks

Since I just started this, I can start over.   

I have a 500GB and two 1TB SSD drive....currently using for Linux (500GB) and MC 27 (1TB) music

So I believe you are suggesting taking the blank 1TB and formatting it with Linux and then copying the files from the Mac formatted drive?

I do Tag editing on the Mac and would like to - from time to time - sync the Raspi disk with the Mac disk - so the Mac will need to read/write to the Raspi drive.

Or I suppose I could keep the above blank drive as a Mac drive and then sync it with the Raspi using SD Copy ??

Wheaten:
Your music is on the USB thingy?
So connect that thing to the rPi, take the empty 1TB drive. As you indicate you want to connect the 1TB to both MAC and rPi, then only FAT32 is compatible. Not exFAT as this will not allow dynamic links. (you can also go for NTFS, but then you need to load additional drivers on your MAC.)
Only issue for FAT32 is the max file size of 4GB, but with music you won't reach this boundary.

You can also share the rPi 1TB disk, with your MAC via a network share.
If you TAG via JRiver, you can set the rPi as main library and have the MAC use this library. Then you can TAG on the MAC, the files from the rPi.

To sync on the MAC, you have Rsync or use filezilla
