Vineet Gupta commented on ZOOKEEPER-3056:
-----------------------------------------
[~hanm] [~enixon] , I tried the workaround provided by you to copy the
snapshot.0 file into the container file system. and then did the rolling update
of my Statefulset in Kubernetes , it didn't still load the database snapshot
and gave the error.
May I please request you to re-check if the steps needs to be done any
differently for container filesystem or if anything is missing there. It seems
to have blocked my couple of projects.
I sincerely appreciate the help !

> With this check, ZK will not load the db without a snapshot file, even the
