The iostat suggests that we are breaking up the wr= ites much more as seen in the wareq-sz field, which is much lower in the regres= sed kernel. Further, since the issue is only when striping is used (ie in raid scenarios) it seems like it has something to do with raiding. Eduard's replicator seems much easier to try so let me see if I'm able to replicate this over a raid setup of HDDs. Regards, ojaswin --=20 You may reply to this email to add a comment.
