I have a large music library on a server that is accessible to Volumio via the network, but the connection is slow. I therefore decided to keep a copy of my music library on a USB disk connected to my RPI/Volumio, and keep this copy synchronized with the server (using rsync and crontab magic during off hours).
However, it looks like I cannot write any changes or new files to the USB drive, because the file system is “read only”:
volumio@volumio:~$ mount | grep sda1
/dev/sda1 on /media/29f709e0-f6fb-4671-b4d8-418d0e8a310f type ext4 (ro,nosuid,nodev,noatime,stripe=8191,data=ordered,uhelper=udisks)
Why is this, and how can I change it?
Edit: I found that the problem occurs with EXT3/EXT4 and NTFS file systems. With a FAT file system, things behave as expected. However, FAT does not work well with rsync, so it’s not a good workaround. Why does Volumio make EXT3/4 and NTFS file systems read only?
