Rather than answer the above questions, I'd rather say that if ext3 is
getting corrupted it's a bug somewhere (or bad hardware) - and if it's
a bug then it needs to be investigated and fixed.

Even before any temporary workaround could be suggested, it'd be most
helpful if you could say what errors you are encountering, with as much
detail as possible (i.e. kernel logs, e2fsck output) and what kernel you
are using.
