RE: ReiserFS vs Ext3
What about XFS? I'm considering using XFS instead of ext3 since it seems to be said that XFS is more stable and efficient than any other linux's journaling fs in the environment of large and not-so-many files. If it is true, I guess that XFS would be the best choice with InnoDB. -- Chung Ha-nyung alita@[neowiz.com|kldp.org] SayClub http://www.sayclub.com NeoWiz http://www.neowiz.com -Original Message- From: David Brodbeck [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 22, 2003 11:10 PM To: Nicholas Gaugler Cc: [EMAIL PROTECTED] Subject: RE: ReiserFS vs Ext3 -Original Message- From: Michael T. Babcock [mailto:[EMAIL PROTECTED]] I would E-mail the reiserfs list and ask for whether ReiserFS would be better for a MySQL-only partition than ext3 and see what answers you get. In the worst case, you'll have some extreme resierfs is always better responses that don't help you decide. In the best (and what I think will happen), someone will tell you the differences in CPU usage or fast file access speeds or some such value that will mean something, or even that it is not actually going to make a difference. If Nicholas does this, I hope he'll report back here with what he finds out. I'm facing the same choice very soon, for a database that will eventually have millions of entries (but each individual entry very small.) I'm trying to decide whether to go with reiserfs or ext3. ext3's my current favorite, but only because it's more of a known, stable quantity. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

resize InnoDB's log file
Currently I have three InnoDB log files, whose size is 256MB and main memory is 2GB. Since I use 1GB of InnoDB buffer pool, I think log files'd better get bigger to some extent; possibly 1GB.

Chung I'd like to configure two servers with two-master scheme, each is the Chung master of Chung another. relay logs should automaticly be deleted and you should never have to do RESET SLAVE to delete them. RESET SLAVE should only be used when you want the slave to not be a part of the replication anymore.

mysql user permission when using raw device instead datafile
Dear After I had mysql use raw device with innodb instead datafile, I started mysql and got an error like following; 021018 14:11:18 mysqld started 021018 14:11:19 InnoDB: Operating system error number 13 in a file operation. InnoDB: See http://www.innodb.com/ibman.html for installation help. InnoDB: The error means mysqld does not have the access rights to InnoDB: the directory. InnoDB: File name /dev/rd/c0d0p3 InnoDB: Cannot continue operation. 021018 14:11:19 mysqld ended mysql and all other files' owner is root and I gave --user=mysql option to mysql. But after omitting the above option, the same error occurred again and only using --user=root option seems to solve this problem. Why mysql would not run in the root permission even thoguh it's owner is root? Or is there any other problem replating to using raw device? Can I NOT run mysql as mysql user permission not root?

RE: loggin all calls made to mysql from php
Use --log-slow-queries[=filename] option. It will log all queries which take more than long_query_time Default value of it is 10 sec and you can ascertain it by show variable like 'long_query_time' query and set in my.cnf as long_query_time = value I think you'd better refer to the MySQL's manual; http://www.mysql.com/documentation/mysql/bychapter/manual_MySQL_Database _Administration.html#Log_Files -- Chung Ha-nyung alita@[neowiz.com|kldp.org] Sayclub http://www.sayclub.com NeoWiz http://www.neowiz.com -Original Message- From: Petre Agenbag [mailto:internet;boesmanland.com] Sent: Thursday, October 17, 2002 7:27 PM To: Á¤ Çϳç Cc: [EMAIL PROTECTED] Subject: RE: loggin all calls made to mysql from php Thanks, I did it and it works. I just would like to know one more thing. You mention a slow log option, how do invoke that type specifically? I restarted mysql with safe_mysqld --log and it created a myserver.log file in the data directory, but it seems to log ALL queries and is growing pretty fast, so the slow option seems a better bet, as I *think* that the slow queries would be the ones most likely to cause the problems anyway?

SHOW SLAVE HOSTS print master host also.
I set up two-way replication with two servers, A and B. Since all queries go to only one server, it seems not to matter. Anyway. When A starts it registers itself to B, and vice versa. I thought query SHOW SLAVE HOSTS to A should shows only about B and B should do about A, but both show the same result as following. +---+--+--+---+---+ | Server_id | Host | Port | Rpl_recovery_rank | Master_id | +---+--+--+---+---+ | 1 | B | 3306 | 0 | 2 | | 2 | A | 3306 | 0 | 1 | +---+--+--+---+---+ Is it right? Why does the result show both master and slave?
