So, I have been able to recreate the case where
lvconvert-repair-raid.sh
keeps failing. It happens when I tried running the reproducer
on a virtual
machine made using a cloud image, instead of one that I
manually
installed. I'm not sure why there is a difference. But I can
show you
how I can reliably recreate the errors I'm seeing.
Create a new Fedora 39 virtual machine with the following
commands (I'm
not sure if it is possible to reproduce this on a machine using
less
memory and cpus, but I can try that if you need me to. You
probably also
want to pick a faster Fedora Mirror for the image location):
# virt-install --name repair-test --memory 8192 --vcpus 8
--disk size=40
--graphics none --extra-args "console=ttyS0" --osinfo
detect=on,name=fedora-unknown --location
https://download.fedoraproject.org/pub/fedora/linux/releases/39/Server/x86_64/os/
virt-install doesn't work well in the my daily dev server. I
will try on a
different machine.
Install to the whole virtual drive, using the default LVM
partitioning.
Then ssh into the VM and run the following commands to setup
the
lvm2-testsuite and 6.6.0 kernel:
[...]
Rerun the lvm2-testsuite with the same commands as before:
# mount -o remount,dev /tmp
This mount trick helped me run tests without a full image (use
CONFIG_9P_FS to reuse host file systems instead). Thanks!
# cd ~/lvm2
# make check T=lvconvert-repair-raid.sh
This fails about 20% of the time, usually at either line 146 or
164. You
can check by running the following command when the test fails.
However, I am seeing lvconvert-repair-raid.sh passes all the
time
with both 6.6 kernel and 6.8+v5 patchset. My host system is
CentOS 8.
shell/lvconvert-repair-raid.sh fails for SLES 15SP5 + upstream
lvm2 +
v6.8+v5 patchset but not with v6.6 kernel.

I guess we will have to run more tests.
DM folks, please also review the set. We won't be able to ship
the
dm changes without your thorough reviews.
Thanks,
