That was back in February/March I think. At the time the server was running a 2.6.18 kernel, since then I've tried a few kernels in between that and currently 2.6.23-rc9 Something seems to be periodically causing a lot of activity that max's out the stripe_cache for a few seconds (when I was trying to look with blktrace, it seemed pdflush was doing a lot of activity during this time). What I had noticed just recently was when I was the only one doing IO on the server (no NFS running and I was logged in at the console) even just patching the kernel was crawling to a halt. > Justin.
