Especially when there are two mirrors on the same two disks... Somehow the head positioning times increase the overall processing time much more than linear... I think it would be a good idea to change the rebuild-strategy (maybe something that is slower; e. g. one rebuild-request per 20 other requests or when there are no pending other requests) in case of high load (e. g. fsck), although that would increase the risk of data loss (another strategy could be, that other requests are delayed until 20 rebuild-requests have been completed). There is another problem in my setting: The rebuild of the other mirror devices that use the same disk(s) should be delayed... -Arne __________________________________________________ Do You Yahoo!?
