resize/increase root filesystem

[donaldUNDdonald]

I have pop os 22.04 with ext4 running as a guest in virtmanager.
The root filesystem is too small and should be enlarged. In virtmanager I increased the guests IDE from 20 GB to 40 GB.
I formatted these additional 20 GB in pop os with disks as a separate partition.

How can I now combine the new partition and the existing root partition?
With the resize option I can only free up space.

Hello,

You can't, unless the boot partition uses a LVM manager.

With the resize option I can only free up space.

If you are booting from a Debian Live ISO image, you can delete the new partition and extend the root filesystem you want to extend. You can use the gparted utility to do this.

Thanks a lot

the debian 10.10.0 live image somehow did not have the gparted tool installed and i could not install it live. But with the gparted live image everything worked out fine.

Would you recommend LVM as standard for new installations?

I'm glad you sorted it out.

I would only recommend LVM to experienced users and if it is strictly necessary for storage needs (i.e. frequent increase/decrease in storage size over time).

For future reference, consider using the "virt-resize" command. It works very nicely with libvirt VMs.
