[Solved] Non-root user cannot access mounted btrfs filesystem

Hello,

So I have a headless server, that is running samba/plex/teamspeak/nginx+php/spigot. I got Plex/Samba running as root at the moment to have my basic home services running, but nginx will refuse to run as root for obvious good reason, so i'm trying to setup the server the right way and move the services away from using root account. I would like all users + to be able to fully read/write to the externally mounted drive.

Currently only root is able to browse the mounted external USB drive, any non-root user gets the following error:

bash: cd: EDATA/: Permission denied

ls -la of the mount point

[root@server mnt]# ls -la
total 24
drwxr-xr-x  3 root root 4096 May 12 11:57 .
drwxr-xr-x 18 root root 4096 May 15 00:45 ..
drwxrwxrw-  1 root root  192 May 13 08:33 EDATA

[root@server EDATA]# ls -la
total 20
drwxrwxrw- 1 root root   192 May 13 08:33 .

# cat /etc/fstab

# BOOT

# Mount EDATA

If anyone is curios i'm using a ECS Liva X with 64GB MMC  + 4GB ram, right now with all the services running it uses around 1.5GB of ram, almost silent setup except for the external 4TB HDD.

Re: [Solved] Non-root user cannot access mounted btrfs filesystem

Without execute permission on the directory, 'other' users cannot not traverse it.

Re: [Solved] Non-root user cannot access mounted btrfs filesystem

Thanks that solved it. This thread can be closed.

Executing chmod 777 to the mount point folder did the trick.

chmod 777 /mnt/EDATA

And to think I spend the whole weekend trying to figure it out, before giving up and posting it.
