(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)
----- Forwarded message 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) a. ----- End forwarded message ----- -- Andrea Mennucc "Ukn ow,Ifina llyfixe dmysp acebar.ohwh atthef" -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
