Welcome to LQ!!
A quick Google search will get you the information on the various Linux filesystems---there are many. I know "RAW" only as a file format used with digital cameras. Did you have something else in mind? If there is a different usage of "RAW", Google will find it. |

There are many more, though, like jfs, xfs, reiserfs, reiser4, and several others. The term "raw" can mean a number of different things. When we talk about a "raw" filesystem we usually mean no filesystem at all. Like on tapes. However looking at your post as a whole I am not sure you mean that at all. So, might I ask you from where did you take this reference to "raw fs" and what exactly your objective is? |
Try
fdisk -l to see what you've got right now Ps that's a lower case 'L' |
Hi,
thanks for reply.I would like to install ORACLE RAC on RAW device which is shared storage and bypass linux buffer cache.How to create RAW FILE system in hard disk. And also how to find the block size of RAW Device |
We need to know if you are talking about a filesystem named "RAW", or--as i92guboj suggested--do you mean NO filesystem?
Here is a Google search which suggests that i92guboj has the right answer----not all the articles either from or referring to Oracle. http://www.google.com/search?hl=en&r...&aq=f&oq=&aqi= |
PS: Assuming that we are talking about a device with no filesystem, then I'm not sure there IS a block size-----i.e. isn't block size a property of a filesystem?
