------- Comment From amit.machhi...@ibm.com 2025-02-18 14:00 EDT------- Hi Olivier,
I further tried recreating this installer crash with multipath disks on a Qemu setup. I followed the below steps: 1. Download the Ubuntu 24.04.1 iso from here: https://cdimage.ubuntu.com/releases/noble/release/ubuntu-24.04.1-live-server-ppc64el.iso 2. Create a qcow2 for provisioning a Ubuntu 24.04.1 guest qemu-img create -f qcow2 /home/amachhiw/images/ubunut-disk.qcow2 10G 3. Provision a guest with multipath disk configuration by running the following Qemu command line. The guest provisioning goes fine as expected. qemu-system-ppc64 \ -enable-kvm \ -m 4G \ -smp 2 \ -boot menu=on \ -device spapr-vscsi,id=scsi \ -drive if=none,id=mpatha,file=/home/amachhiw/images/multipath-disk.qcow2,format=qcow2,file.locking=off \ -device scsi-hd,drive=mpatha,serial=MPIO \ -drive if=none,id=mpathb,file=/home/amachhiw/images/multipath-disk.qcow2,format=qcow2,file.locking=off \ -drive file=/home/amachhiw/images/ubuntu-24.04.1-live-server-ppc64el.iso,media=cdrom \ -device scsi-hd,drive=mpathb,serial=MPIO \ -net nic,model=virtio \ -net user,hostfwd=::15447-:22 \ -nographic 5. Try a re-provision of the guest: a. Once provisioning completes and reach to the login prompt, just login and reboot. b. Keep hitting F12 for getting into the boot menu and boot from the cdrom 6. Follow the on-screen instructions for proceeding on the installer. Eventually, during the installation, the installer crashes with the below Traceback Traceback (most recent call last): File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/commands/main.py", line 202, in main ret = args.func(args) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/log.py", line 97, in wrapper return log_time("TIMED %s: " % msg, func, *args, **kwargs) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/log.py", line 79, in log_time return func(*args, **kwargs) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/commands/block_meta.py", line 118, in block_meta meta_clear(devices, state.get('report_stack_prefix', '')) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/commands/block_meta.py", line 2213, in meta_clear clear_holders.clear_holders(devices) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/block/clear_holders.py", line 638, in clear_holders shutdown_function(dev_info['device']) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/block/clear_holders.py", line 138, in shutdown_lvm util.subp(['lvremove', '--force', '--force', vg_lv_name]) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/util.py", line 323, in subp return _subp(*args, **kwargs) File "/snap/subiquity/6065/lib/python3.10/site-packages/curtin/util.py", line 172, in _subp raise ProcessExecutionError(stdout=out, stderr=err, curtin.util.ProcessExecutionError: Unexpected error while running command. Command: ['lvremove', '--force', '--force', 'ubuntu-vg/ubuntu-lv'] Though this is not exactly the same as the original issue being discussed in the bugzilla, I have again been able to recreate this installer crash with 100% hit. Additionally, I observe the above errors mentioned in https://bugzilla.linux.ibm.com/show_bug.cgi?id=208604#c51 as well.

Also, please note that the installer does *NOT* crash when the above steps are followed WITHOUT multipath disks. The re-provision of the guest goes fine every time with normal disks.
