Cannot run minimserver from external disk - peterr - 22-11-2020 17:17

Hello,

I'm successfully using minimserver2 on a headless Raspberry Pi 4 running Arch Linux (aarch64). I installed it in my user's home directory (/home/peterr).

Now I would like to install minimserver2 on an external disk mounted in /mnt (/mnt/ssd2). But when I try to run any script from minimserver/bin from there, I get permission errors. I didn't use root or sudo at any point during installation.

Here's a complete history of what I did:

Code:
[peterr@pi4 ssd2]$ tar xf MinimServer-2.0.16-linux-arm64.tar.gz

[peterr@pi4 ssd2]$ minimserver/bin/setup
-bash: minimserver/bin/setup: Permission denied

[peterr@pi4 ssd2]$ minimserver/bin/startc
-bash: minimserver/bin/startc: Permission denied

Permissions look fine, though:

Permissions for /mnt are write-restricted to root, but this is identical to /home:

Code:
[peterr@pi4 ssd2]$ ls -l /

drwxr-xr-x   3 root root  4096 Nov 21 00:22 home
...
drwxr-xr-x   6 root root  4096 Nov  8 20:39 mnt
...

Is there anything I can do about this?

Edit: Maybe a note on the java version is helpful:

Code:
[peterr@pi4 ~]$ java -version
java version "1.8.0_271"
Java(TM) SE Runtime Environment (build 1.8.0_271-b09)

Is ssd2 mounted with noexec?

Not explicitly, but I just found out that the mount option 'users' implies noexec. Mounting with the option 'exec' should solve this, thank you!
