I complained about a year ago about the poor support in freebsd for ataidle, and I got several replies somewhere between indifference, and outright flames, and this from Europeans, who are regarded as somewhat more enlightened on the subject... My server has about 6 disks in it, in several raid configurations, and they're all 7200 or 10k rpm drives, so disk power usage is paramount for me. A good deal of things (i.e. CVS!) choke bigtime when a disk is spun down and they attempt to acess it. Apache used to timeout, but lately, it seems to just wait patently for the disk to spin up then load the page - I will hope this was deliberate...in the meantime, I should probably be on SVN instead of CVS anyway. I still see lots of ugliness in dmesg regarding the disks, but everything seems to function, and I haven't lost any data or commits... Best, Steve
