Yes. The node starts and is in Primary state.

I'm not sure what the logs will show you, I've never seen any indication of the tar unpacking in any JOINER logs ever. My simulation was a reasonable situation:

node goes down
table gets dropped
node rejoins with SST
tablespace incorrectly still in place, even after SST and node joins

Reading wsrep_sst_xtrabackup, I don't see any reason why you would think this would even work right. What is in the script that would ensure the JOINER's datadir would get clobbered? The default tar command is simply:

            strmcmd="tar xfi - -C ${DATA}"

and -C doesn't stand for "clobber".
