- While we are using Oracle instead of Informix, some points are common.
-
- 1. There is usually a performance increase when using raw partitions
- instead of the file system. Usually the RDMS can do a better job of
- getting to the data than a general purpose file system.
-
- 2. Many of the normal UNIX tools break with raw partitions. Since
- it is not a true file system the tools can't access the data to give
- directory listings, file sizes or do backups, etc.
-
- 3. If your application requires mirroring of the drives, LVM will
- not be able to help you. You are at the mercy of your RDMS vendor.
- In our case, this is a compelling reason to NOT use raw partitions.
-
- For what its worth. Of course the opinions are my own, blah blah blah
