Thanks Markus,
but /mnt/datastore/ is already clean with only the datastore active.
Anyway in this folder /etc/systemd/system/multi-user.target.wants/ they do not appears the datastore:
root@pve:/etc/systemd/system/multi-user.target.wants# ls -larth | grep st1
root@pve:/etc/systemd/system/multi-user.target.wants# ls -larth | grep sea
root@pve:/etc/systemd/system/multi-user.target.wants# ls -larth | grep s8i
root@pve:/etc/systemd/system/multi-user.target.wants# ls -larth | grep datastore
lrwxrwxrwx 1 root root 45 Sep 17 2021 mnt-datastore-wb500.mount -> /etc/systemd/system/mnt-datastore-wb500.mount
lrwxrwxrwx 1 root root 45 Sep 23 10:13 mnt-datastore-mx5t1.mount -> /etc/systemd/system/mnt-datastore-mx5t1.mount
root@pve:/etc/systemd/system/multi-user.target.wants#
mx5t1 is the active datastore, all othe that you can see in the image, are not present and or connect to this proxmox.
While wb500 is dead and not connected.
Can you help me to understad ? Thanks
