Full graceful restart without bootstrap, pc.recovery=true hangs: no gvwstate.dat!?


I tried to do a full cluster graceful restart without bootstrap, and relying on the pc.recovery=true feature + gvwstate.dat.

“This feature can be used for automatic recovery from full cluster crashes, such as in the case of a data center power outage and graceful full cluster restarts without the need for explicitly bootstrapping a new Primary Component.”

However, gvwstate.dat was deleted on graceful shutdown, so all the daemons hung on reboot.

systemctl stop mysql
ls -l /var/lib/mysql/gv*
No such file or directory

How is full graceful restart supposed to work?
