Yes, but have you kept up to date with new kernel releases from Red
Hat? They're pretty good about releasing patched kernels if there is
a problem.

Shut down the database, I'm afraid, and copy the data directory
before you start doing things.

So far as I've heard, the cases of clog file corruption have all been
related to hardware. You'd best think about replacing your disk or
your controller. Have you had any crashes lately? Anything unusual?
Are you using ECC RAM? (If not, are you sure you don't have bad RAM?
If you got a bad bit written at the wrong time, you'd have a real
mess.)

As I understand it, you need to zero out the file with dummy data in
order to get going again. You really need to plough the archives for
what to do, though. I've never had to do this.
