This is my first time posting here and it is just for asking...!!! Well, we are building a project for our customer wich is basically a searcher, google style. We use mnoGoSearch as indexer, 3.2.27-mysql, to more specific.!. We already try lots of version even compiling from source to discard indexer as a problem. The database, wich is about 20 gb and increasing!!!, is distributed among 5 server, 4 of 5 has SATA disks, 2 gb RAM, the 5th, is 512 mb ram and 80 gb SCSI 3 disk with adaptec 2940U as host scsi adapter. Well, after lots of testing, if you enter on the site, aka: www.lomejordetodo.com.ar, and type a text to search to. it takes about 5 minutues if query has lots of result, like linux kernel query. We read lots of posting, messages and googling but we couldn't solve the problem at all!. If anyone here has o had the same problem I'l give lots of thanks if you could show me the path to investigate.

Master-Slave replication error: Last_Errno: 1146
Hi all. I have 2 MySQL servers. One master and one slave. In order to add new slave server, and because i can't stop the master one, i have tried this: http://forums.mysql.com/read.php?26,99846,102058 *You don't have to modify the other slaves configuration. What you need to do is obtain a snapshot of the data on those slaves with their current position relative to the master. The easiest way to do this is to stop mysql on one of the slaves and copy it's data directory (except for the bin logs) and my.cnf to the new slave. Then start the old slave so it doesn't get too far behind in replication. On the new slave change the server-id in my.cnf so it's unique from the other servers. Add skip-slave to my.cnf. Start mysql, login and run show slave status\G Then run the following command substituting the $values from the show slave status change master to master_log_file='$Relay_master_log_file', master_log_pos=$Exec_master_log_pos; Then start the new slave; Once replication catches up it's good to go :)* The issue is when i do START SLAVE; i obtain this error: Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1146 Last_Error: Error 'Table 'XX.y' doesn't exist' on query. Default database: ''. Query: 'INSERT INTO y ' MySQL Server version: version 5.0.32 . Any idea ? Many Thanks. -- Salah NAIT-MOULOUD Echovox - www.echovox.com m-Boost - www.m-boost.com
