What's wrong ?

Run "dmesg | paste" and look for errors when the automount attempts to mount the drive. If the mount state is 'dirty' you may need to fsck the drive first to clear the flag before automount can succeed.

I didn't see any error about sdd.

How can i increase log level and see specific log about disk mounting processs ?

"journalctl | paste" and share the URL

fanch_95 · January 24, 2021 at 11:56 AM

Thank's Chewitt.

Please find in attachment output from command line :

# journalctl | egrep -v "ntp|kodi.sh|tun0|eth0"

It seem last line "LibreELEC systemd[1]: var-media-ST_2TB.mount: Succeeded" come from my workaround to mount /dev/sdd1 in ksh script "~/..config/autostart.sh" executed at startup.journalctl.txt

# cat autostart.sh

#!/bin/sh

mkdir -p /media/ST_2TB

mount /dev/sdd1 /var/media/ST_2TB -o nosuid,nodev,noexec,noatime

I think you need to dig into udev (udevadm) to see what information it has on the drive and thus perhaps why it's not matching the mount rules

in addition fsck output :

Good point Chewitt. It seems udev flags are persistants even after deleting partition :

# udevadm info /dev/sdd1

...

E: ID_FS_VERSION=5000

E: ID_FS_TYPE=zfs_member

....

This disk come from my NAS with zpool partition (zfs V5000 filesystem). Probably, I should destroy zpool before using the disk !

I take a look to fix it.

fanch_95 · January 25, 2021 at 6:23 PM

Partition was delete and recreate with gparted.

The udev flags has been reset with news and good values :

...

E: ID_FS_VERSION=1.0

E: ID_FS_TYPE=ext4

....

Now automount partition works fine.

I change mount point with e2label to finish my setup.

Special thank to Chewitt bringing me on the right way.
