I have setup a server with LVM, and at first I juset created a small logical volume named 'root' of about 10GB, but later changed my mind. I extended it to 1TiB, but my server still is in two minds of how big the partition (or mountpoint, I'm not sure) actually is.

I used the #lvextend command in the console to extend the logical volume, not through webmin.

Here's a screengrab from webmin that maybe shows it more clearly.

I'm guessing you're expecting more free space... lvextend resizes the logical volume, you also need to resize the filesystem:

resize2fs /dev/Hulkvg/root

(as root; I don't know how to do that through the Webmin interface).

  • That did it. ˋsudo resize2fs /dev/mapper/Hulkvg-rootˋ to be precise. I have access to a console on the server, I just used webmin to illustrate the issue. Thanks a lot. – Sindre Bjørnhjell Mar 30 '16 at 17:02
