I don't know about the last field, but having -1 io's running seems kinda unlikely.... This only happens w/ the IDE disks. [OK, before posting I googled somewhat and found some references to this problem. They did not mention the following though.] Another weird thing is that the "use" & "aveq" fields for hda & hdb are incremented and decremented (respectivly) by 1010 every second (to be clear: whole disk only, not the stats for hd[ab]1). This happens while the partitions are mouted, unmounted and even when the disks are spinned down (by BIOS PM(?)) It's not a real problem for me but I thought I'd report it. If you request more info pls. CC me, I'm not on the list. Regards, Mark.
