[Bug 1935969] Re: Ubuntu 20.04.2 LTS installer crash when letting the system determine size of additional LV

[Conny Molin]

No, encryption haven’t been enabled. Just a plain vanilla vm with a
single disk (hw ver 13, paravirtual scsi controller, thin provisioned
disk residing on a Netapp flash SAN).

I’ve worked around it already so I don’t have a .crash file at the time
of this writing. It’s easily reproduced though so I’ll deploy a new vm
in the morning and get you that file.

Anything else you know you might need to aid in this investigation?

Title:
  Ubuntu 20.04.2 LTS installer crash when letting the system determine
  size of additional LV

Status in subiquity package in Ubuntu:
  New

Bug description:
  Tested on VMware ESXi 6.5/6.7

  Trying to install a VM using the graphical installer and using i.e. a
  60GB disk, letting the system autoprovision the required partitions
  naturally creates a VG on the entire disk, and an LV of roughly 50% of
  the VG size. If you then create a secondary LV on the same VG and do
  not fill in the size of the LV, the system should claim all remaining
  space. However, this causes the installer to crash, not instantly, but
  a few seconds after having confirmed the partition layout (when you
  are on the user creation part of the install).

  Lowering the size of the additional LV by as little as ~500MB solves
  the issue and the installer runs just fine through everything.
