You want to reinvent the drum? matt,=20 when i recall it right, someone told me about a paper presented at usenix about logging to a single disk which is exactly the thing that would do the job here. it was, i think, discussed in a very terse fashion on -hackers last year. the idea was that a single disk for logging purposes would be sufficient in terms of spindle speed and much cheaper than a raid setup and it would not require from-scratch development of a log structured filesystem because it would sit between the fs abstraction and io layers. /k --=20 > May the source be with you!
