Disk resize with GParted gone wrong

Ask Fedora
1

I wanted to grow the root partition on a Fedora server from 15GB to 36GB. The operation completes and the server comes back up but something has gone wrong. It’s a new server so it won’t be a big deal if I have to rebuild it. But I’d like to understand where I went wrong.

Referencing the attached I have grown sda3 to 36GB

but the result looks very different

and this is GParted after the above operation

which again is very different to the actual partition table.

Any ideas?

sudo pvresize /dev/sda3
sudo lvextend -r -l +100%FREE /dev/mapper/fedora*-root

If the issue persists, check the output:

sudo vgs; sudo pvs; sudo lvs; lsblk -f -p

Thanks for getting back. Couple of errors…
