I installed and configured fedora over the weekend (first time I've looked at linux since setting up my last server 2 years ago!).

Now that I've got everythting (almost) working as I want it, I've remembered that noflushd doesn't work with ext3.

Can anyone tell me how to convert from ext3->ext2 without having to reinstall/configure?

thx.

It is a matter of just removing the journal. However, I could not find any directions on if this can be safely done, or how to do it. Most of the google hits are the other way. :p

man tune2fs.

But if you need ext2 to use noflushd, I'd recommend sticking to ext3 and doing away with noflushd. Look at something like "hdparm -S" instead. ext3 really will give you *much* better reliability, particularly if you're running from an unreliable power source (like batteries!).

Thanks, that's done the trick.
