Is it during clvmd initialization only?
yes. where else could it occur?
clvmd tries to initialize locks for possible already activated volumes
(mostly safety/force restart check, clvmd must start before clustered LVs
are activated anyway)
It simply run lvs command (forcing nolocking for this command)
to check which volumes are activated.
The log message is misleading here...
the LVs are imho not activated but CLVMd still complains about disabled
