OK. Created 50_thin_block_extension_rules.conf under /etc/vdsm/vdsm.conf.d
and restarted vdsmd

One last (latest probably... ;-) question
Is it expected that if I restart vdsmd on the host that is the SPM, then
SPM is shifted to another node?
Because when restarting vdsmd on the host that is not SPM I didn't get any
message in web admin gui and restart of vdsmd itself was very fast.
Instead on the host with SPM, the command took several seconds and I got
these events
