Re: Can we build a proper email cluster? (was: Re: Why is debian.org email so unreliable?)
(reposting from private)
note that what I state below *is* possible, as pointed
by someone in d-private, by using a mke2fs option
$ mke2fs -J device=
(and of course you need to use a nonvolatile kind of ramdisk)

now that I come to think of it...
there would be a wonderful solution to the problem of journalling:
keeping the journal in another, faster, device!
the best would be to have a filesystem that keeps the main data
in hard disks (cheap but slow) and the complete journal (metadata AND
data) in RAM disk (or similar) (which would be more expensive by
the GB, but much much faster).
This would be somewhat difficult to implement
in kernel, and difficult to properly setup, but it may
be very effective. It would entail a /etc/fstab such as
/dev/hda1 / ext3 default,journal=/dev/ramdisk/1 0 1
/dev/hda2 /usr ext3 default,journal=/dev/ramdisk/2 0 1
...
where /dev/ramdisk/* are partitions in the ramdisk.
(Now that I think of it, this e-mail has nothing private in it :-(
sorry for the abuse of d-p)
