I have been using Volumio with external thumb drives for some time now and have always formatted them as FAT32. I decided that ext4 would be better (as I do have some special characters in my filenames). However, although my ext4 disk mounts quite happily, Volumio cannot see it (although the files are there if I ssh in and use
sudo ls
So before I insert the disks my file structure looks like:
drwxrwxrwx 2 volumio volumio 1024 Feb 14 14:12 PI4MUSIC
drwxrwxrwx 2 volumio volumio 1024 Feb 14 14:12 PI4RIP
drwxrwxrwx 2 volumio volumio 1024 Feb 13 23:51 TEMPRIP
and after I insert the thumb drives
drwxrwxrwx 8 root root 32768 Jan 1 1970 PI4MUSIC
drwxrwxrwx 54 root root 32768 Jan 1 1970 PI4RIP
drwx------ 54 root root 4096 Feb 14 13:08 TEMPRIP
The first two disks are formatted FAT32, the 3rd ext4. So it looks like a permissions problem as only root can read the disk. At the next level down i.e. the directories that hold the albums, the permissions are fine i.e. every directory and file is read and writable by everyone (and owned by root). I did see another post about auto mounting not happening but my problem seems different (as my disks are auto mounting). In the solution there, it was suggested that a diagnostic is
sudo parted -s /dev/sda unit MB print
Model: SanDisk Ultra Fit (scsi)
Disk /dev/sda: 124219MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
Number Start End Size File system Name Flags
1 1.05MB 124217MB 124216MB ext4 SPARERIP
Don’t know if this helps but I welcome your suggestions as to how to make automount mount as world rwx for ext4 volumes as it does for FAT32
Many thanks
