Re: Raw Disk still preferred for 11.5? - File system type for SDS
In a thread on file system choice for SDS and raw disk on 11.5, John Carlson said he had heard ReiserFS and journaled file systems like ext3 were poor for databases. Obnoxio The Clown said they were terrible and Superboer added they could lose or corrupt data. InDeep noted OCFS is a shared-disk file system built for Oracle RAC and pointed to VxFS. No recommendation was settled.

I've heard that RieserFS isn't good for databases, as well as ext3 (or any other journaled file system). And make sure those pesky SysAdmin / Operations-type people don't get frisky with the "rm" command. As far as I know in the *ixes, there is no "unrm". 8-)

Well, since you're late again to the party John, what, 2 weeks later... OCFS is designed for shared disk implementations. It was designed specifically for Oracle so you can implement RAC and other configurations. A small amount of research can answer a lot of questions.
