In the meantime I figured out what happened and would like to share my findings
for everyone else to avoid my mistake.
The mentioned change to lvm.conf is done by set_lvm_conf in the postinst script
of pve-manager (see /var/lib/dpkg/info/pve-manager.postinst).
During the update I had accidentally pressed Enter when asked what should
happen with /etc/lvm/lvm.conf.
======================
Setting up lvm2 (2.03.16-2) ...
Configuration file '/etc/lvm/lvm.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** lvm.conf (Y/I/N/O/D/Z) [default=N] ?
…
Setting up pve-cluster (8.0.3) ...
…
Setting up pve-manager (8.0.4) ...
...
======================
That kept the currently-installed /etc/lvm/lvm.conf and saved the (Debian)
package maintainer's version in /etc/lvm/lvm.conf.dpkg-dist.
The currently-installed lvm.conf (from PVE7.4) contained the correct
global_filter and was therefore subsequently not touched by
pve-manager.postinst during the upgrade to 8.0.
After the upgrade (and reading through [1] again) I noticed my mistake, took
lvm.conf.dpkg-dist and copied it over lvm.conf.
That’s why pve-manager.postinst was not able to change the global_filter in the
package maintaner’s version.
I had better selected to “Y” to install the Debian-maintained version of
lvm.conf and let pve-manager.postinst do it’s job right away.
Running "dpkg-reconfigure pve-manager” and rebooting the machine solved the
issue for me.
