You need to say what filesystem you're using, but for XFS as an example it is optimized for placement on RAID, therefore it spreads the data out as much as it can in hopes that the data ends up split across lots of spindles and therefor the parallel nature of raid gets full benefit.
That makes no sense what so ever. Raid doesn't work that way. Everything is mirrored or everything is spread across spindles depening on which raid you choose. And as a general comment on this thread, people need to stop thinking about micromanaging how data is stored on drives and let the OS and the FS do its job. Virtually any File system will do a better job of this than any fiddling by the user. Unless you have large static files, it only matters on initial disk loading anyway, because that is the last time you will be able to influence location of a file on the disk. Virtually ANY Linux file system won't need defraging, ever. -- Explain again the part about rm -rf / -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
