G'morning all! (Using Red Hat Linux Enterprise 4.1) I have a Dell PowerEdge 2800 with a PERC 4 RAID controller. The RAID controller has one RAID 1 mirror and one RAID 5 stripe volume created. We installed most of the OS stuff on the RAID 1 set and the /usr/local and /var on the RAID 5 set (since the Red Hat MySQL rpm puts the data directory under /var ).
I'd like to know if there are any better ways to configure this (I can repartition and reinstall the OS, if necessary). <background> I'm having problems with a Tomcat application (OSP - ePortfolios) that uses a lot of disk space for uploaded files (under Tomcat directory which I install under /usr/local). Not sure how large the MySQL database will grow to be. I installed the Red Hat MySQL rpm, but not sure if it is RAID-aware and considering compiling MySQL from source ( --with raid ?). Or my problem may be with the MySQL Connector/J driver (which would be a question for the mysql-java list). The application builds and installs fine with no errors, but Tomcat only works for the static directories (i.e. /jsp-examples ) and not with the application that interacts with MySQL. I've installed this application successfully on an identical non-raid system. The only differenced between the two machines is that the problem child is RAID (configured as above) and the java sdk version changed from _08 to _09. </background> 1) Best way to configure the RAID/partitions for best MySQL performance? 2) Is MySQL RAID-aware if not compiled: - - with raid? (unsure if the Red Hat rpm used that) 3) Is there a way to tell if a problem is specifically related to the MySQL Connector/J driver or a problem connecting to MySQL? (probably should direct that one to the mysql-java list, eh?) Thanks in advance for any help. This is the first RAID machine I've ever worked with. : \ Darren Addy University of Nebraska at Kearney -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
