Expanding dom0 after partition size increase

[groverj]

I have a dual boot set up, and have recently increased the size of the hd partition I wish to allocate to QubesOS.

N.B. I made sure to clone the entire disk before starting as a precaution!

Here is what I have attempted thus far:

I successfully increased the size of the dev/sda4 partition using a live usb of gparted, and subsequently the /sda5 partition within - this worked, but of course, the LUKS encrypted partition on which dom0 resides does not automatically expand as a result. Qubes boots exactly the same as before, showing no changes.

From what I've read, I believe this to be a multi stage process requiring a resize of the file system, but most of the instructions I can find seem to refer to an older version of gparted (and use commands such as 'resize' that apparently do not work on versions of libparted 3+).

What would be the next step in expanding the space available to dom0?

groverj:

Nothing unique to Qubes, so any existing docs covering resizing LUKS
encrypted LVM partitions would be similar (e.g.
https://help.ubuntu.com/community/ResizeEncryptedPartitions). Only
wrinkle is most Debian LiveCDs don't include the thin-provisioning-tools
package, so apt install it before resizing.
