Hi, I´m running a mySQL-Cluster with drbd/pacemaker/heartbeat on two centOS 5.7. The old version was a mysql-server-5.0.77-4.el5_6.6 the new is mysql-server-5.0.95-1.el5_7.1. I tried to update the system with less downtime, so first update via yum was on the passive node (2 drbd-devices as slave, no mysqld started) and was no problem also after reboot eveything looked fine. Then I tried to switch the database over to the passive second (updated) node. But the mysqld was unable to start on that machine. I did the update (and reboot) also on the active node and there is no problem with the mysqld. This is a part of /var/log/mysqld.log

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. key_buffer_size=0 read_buffer_size=2097152 max_used_connections=0 max_connections=4000 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 16384000 Kbytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=(nil) Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... frame pointer is NULL, did you compile with -fomit-frame-pointer? Aborting backtrace! The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains information that should help you find out what is causing the crash. 120223 15:46:44 mysqld ended Any suggestions are welcome kind regards fatcharly -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql
