Enable Root User after storage pool deletion

Is there a way to enable the Root User on a Hyperscale 1.5 node from command line?

It was disabled when we deleted the storage pool and I was unaware we cannot run the umount command as the cvbackupadmin user.

You should be able to regain root access using the following steps below, you will need to have Console access via kvm or ipmi or equivalent:

During the system boot, hit the esc key to gain access to the grub menu
Select/highlight the kernel version in the Grub menu using the Up/Down arrow keys and press 'e' to start editing.
Scroll down to the line starting with linux/linux16/linuxefi.
Go to the end of the line and add the string “rw init=/bin/sh”
Press Ctrl-x to accept the changes and boot.

Once you’ve gained access, run the command #passwd and enter in a new or existing password, this will re-enable the root with the password entered.

One done, reboot using #/usr/sbin/reboot -f

Is ‘nodes’ missing from the storage → HyperScale view because the storage pool was deleted?

Yes we are decommissioning the appliance. The documentation page called out deleting the storage pool then running commands to stop the cluster.
