It is not the temporary directory specified on command line at the end which is the problem:
perl /usr/bin/innobackupex --defaults-file=/run/shm/galera0/mysql/etc/my.cnf --user=root --password=rootpass --socket=/dev/shm/galera0/mysql/var//mysqld.sock --galera-info --stream=tar /tmp
It is the temporary directory which xtrabackup uses, passed in --tmpdir which is /tmp by default.
Anyways, I am thinking of working around this.
