OpenStack: How to fix a drive stuck on deleting.
How to fix an openstack drive stuck on deleting.
On Ubuntu 16+ you can use hostnamectl to change the hostname via:
hostnamectl set-hostname <new name>
To Change a hostname on Ubuntu use an editor like vim or nano to edit /etc/hostname
sudo nano /etc/hostname
Erase the old hostname and add the new one
Next you will want to edit the /etc/hosts file and replace the old hostname after 127.0.1.1 to the new hostname
sudo nano /etc/hosts
Now verify with:
hostnamectl
And you should get a response as follows:
Static hostname: doublebracket
Icon name: computer-desktop
Chassis: desktop
Machine ID: ca6bba1fbb154992a5fe74d564b42e22
Boot ID: 1d92d7c3d74f494eaba5eb9a078894f9
Operating System: Ubuntu 19.10
Kernel: Linux 5.3.0-26-generic
Architecture: x86-64
Note: You may see tutorials that say just use hostname <newhostname>. This will create a tranisent hostname, i.e one that will not survive a reboot. Aftering setting a hostname in this way you will see it when you type hostname. However if you type hostnamectl you will see it listed as transient. You can see the example output below:
