How do I extend the lvm after adding a new drive to the system?

[eagle275]

Like headline says .. I have a proxmox pve on a beelink system, created a few vms and now added an additional drive to extend diskspace.
After installation proxmox had created an lvm , if possible I want to extend that and add the new drive's space to the available pool

If the question lacks necessary information, please ask .. I'll provide whatever might be needed

Hi @eagle275 , welcome to the forum.

Your question is not PVE specific, but rather related to general Linux administration.

You can plug this into your favorite search engine "how to extend lvm with new disk".

There are many suitable results. I would recommend, however, to read entire article first and ensure that you understand the steps.

If you, like me, find it hard to visualize LVM from commandline... Install webmin (runs on port 10000) and/or WeLees

https://www.welees.com/lvm-support.html

Just be aware that the WeLees webserver uses 100% CPU. You can kill -18 (SIGSTOP) the pid // kill -19 (SIGCONT) when you're ready to use it to save CPU.

Webmin helped me recently to allocate the remaining LVM free space for rootfs, it was literally a 1-button fix.
