Yes it throws the following:
This is the recommended LVM filter for this host:

"r|.*|" ]
This is not complete output - did you strip the lines explaining why
we need this
filter?
This filter allows LVM to access the local devices used by the
hypervisor, but not shared storage owned by Vdsm. If you add a new
device to the volume group, you will need to edit the filter manually.
This is the current LVM filter:
filter = [
"a|^/dev/disk/by-id/lvm-pv-uuid-3QbgiW-WaOV-ejW9-rs5R-akfW-sUZb-AXm8Pq$|",
"a|^/dev/sda|", "r|.*|" ]
So the issue is that you likely have a stale lvm filter for a device
which is not
used by the host.
To use the recommended filter we need to add multipath
blacklist in /etc/multipath/conf.d/vdsm_blacklist.conf:
blacklist {
wwid "364cd98f06762ec0029afc17a03e0cf6a"
}
WARNING: The current LVM filter does not match the recommended filter,
Vdsm cannot configure the filter automatically.
Please edit /etc/lvm/lvm.conf and set the 'filter' option in the
'devices' section to the recommended value.
Make sure /etc/multipath/conf.d/vdsm_blacklist.conf is set with the
recommended 'blacklist' section.
It is recommended to reboot to verify the new configuration.
I updated my entry to the following (Blacklist is already configured from before):
filter = [
"a|^/dev/disk/by-id/lvm-pv-uuid-DxNDT5-3NH3-I1YJ-0ajl-ah6W-M7Kf-h5uZKU$|","a|^/dev/disk/by-id/lvm-pv-uuid-Yepp1J-dsfN-jLh7-xCxm-G7QC-nbaL-6rT2KY$|","a|^/dev/sda|","r|.*|"
]
although then it threw this error

I'm not sure if this error comes from the code configuring lvm filter,
or from lvm.
The best way to handle this depends on why you have lvm filter that
vdsm-tool cannot handle.
If you know why the lvm filter is set to the current value, and you
know that the system actually
need all the devices in the filter, you can keep the current lvm filter.
If you don't know why the curent lvm filter is set to this value, you
can remove the lvm filter
from lvm.conf, and run "vdsm-tool config-lvm-filter" to let the tool
configure the default filter.
In general, the lvm filter allows the host to access the devices
needed by the host, for
example the root file system.
If you are not sure what are the required devices, please share the
the *complete* output
of running "vdsm-tool config-lvm-filter", with lvm.conf that does not
include any filter.
