You been doing zero length IOs again? :) How many zero length IOs can you do in a second? -----Original Message----- From: linux-raid-owner@xxxxxxxxxxxxxxx [mailto:linux-raid-owner@xxxxxxxxxxxxxxx] On Behalf Of maarten Sent: Monday, January 10, 2005 1:41 PM To: linux-raid@xxxxxxxxxxxxxxx Subject: Re: Spares and partitioning huge disks On Monday 10 January 2005 18:13, Guy wrote: > I have 4 of these: > raid5: switching cache buffer size, 4096 --> 1024 > > And 2 of these: > raid5: switching cache buffer size, 1024 --> 4096 Another thing that only strikes me now that I'm actually counting them: I have _exactly_ 24 of those messages per minute. At any moment, at any time, idle or not. (Although a PVR is never really 'idle', but nevertheless) (well, not really _every_ time, but out of ten samples nine were 24 and only one was 36) And this one may be particularly interesting: Jan 9 02:47:19 dozer kernel: raid5: switching cache buffer size, 512 --> 4096 Jan 9 02:47:24 dozer kernel: raid5: switching cache buffer size, 0 --> 4096 Jan 9 02:47:24 dozer kernel: raid5: switching cache buffer size, 4096 --> 512 Switching from buffer size 0 ? Wtf ? Another thing to note is that my switches are between 4096 and 512, not between 4k and 1k as Neil's reply would indicate being normal. But I don't consider this bit really important.
