What's Causing My External USB HDD To Mount After A Reboot?

[mhayhurst]

Hello Everyone,

Using Proxmox 6.2-14, is there anything built in to Proxmox outside of: /etc/fstab that would cause my external USB HDD to mount after a reboot? I previously added this USB HDD under: Datacenter --> Storage --> Add --> Directory but it has since been removed and is not listed anywhere in /etc/fstab. After I reboot my Proxmox machine the drive still mounts. Also, this machine is not part of any cluster.

root@proxmox2:~# mount

/dev/sdb1 on /mnt/pve/backup_storage type ext4 (rw,relatime)

root@proxmox2:~# cat /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
/dev/pve/root / xfs defaults 0 1
UUID=77E6-E5BD /boot/efi vfat defaults 0 1
/dev/pve/swap none swap sw 0 0
proc /proc proc defaults 0 0

You could see in systemd

ls /etc/systemd/system  | grep .mount

So mounting can happen in systemd and in the fstab file? I assume this systemd entry was not deleted when I deleted the external drive from Datacenter --> Storage?

Thank you for this! I guess I'm confused on why Proxmox is mounting via systemd versus /etc/fstab? Is this the new standard when it comes to mounting?
