The specific issue I'm referring to at this point is on a system running mysql. All mysql data files are on a netapp filer but mysql's tmp directory is on local disk. Whenever a lot of temp tables are created (and thus written and deleted from local disk quickly) we can't even log in to the machine - and our monitoring system gets all freaked out and we get lots of pages, etc... FYI this is two disks with hardware raid 1. Is it just me? Or is this specific to Dell systems, or is this just the state of the Linux kernel these days? Is there some magical patch I can apply to make this issue go away :)
Does the Dell have a raid controller? I saw something like this long ago on a Dell with a raid card that appeared to queue up thousands of operations, then hit some kind of high water mark and stay busy (basically locking the system) for several minutes while it caught up. It seemed pretty fast as long as you never completely filled its queue... These days I mostly run software raid1.
