I am trying to add a node to a new cluster but am met with the following log entries:

My node1 (
gcomm://) starts and shows 1 node in cluster. I updated node2 to point to node1, restart, and the following appears consistently, causing MySQL to crash.
It looks like part of the issue may be related to
rsync failing allong with
Unknown error 255.
My node1 is
10.1.1.1 and listening on
4567 (by default).
Update: I changed SST type to
mysqldump and it started working. But since then, performance has been very poor:
mysql> show databases; ERROR 2006 (HY000): MySQL server has gone away No connection. Trying to reconnect... ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) ERROR: Can't connect to the server mysql> show databases; No connection. Trying to reconnect...

Also, this is located in
19:41:41 UTC - mysqld got signal 6 ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.
