The drives are designed for very power efficient archive use and they have a very aggressive spin down timer. Once they drop to a slower speed or stopped it will take a significant time to get back up to ready. I would highly suggest updating to code AR14 or AR15. The drives aren't really intended for your use model. Perhaps a cron job that does a dd read (direct mode) of a hundred MBs or so from the md device to dev/null every couple minutes might be enough to keep them warm and not spun down. --Jeff On 8/14/15 10:52 AM, Tejas Rao wrote: > I am aware that the Seagate SMR 8tb archive drives are not meant to be > used in a RAID environment as they lack TLER/ERC support. > > We are trying to use these drives with mdraid and are seeing problems. > It seems that after writing to these drives for few hours, > occasionally some drives stop responding for few minutes and recover > on its own later.
