Hi, I eagerly started using atacontrol's new spindown command the other day. There's a gmirror volume running on top of the two disks that get spundown. I find that often when the drives are spun back up to serve a disk request, one of the ata devices times out and my system goes into a never ending loop of retrying. At that point I'm lucky if I'm able to shutdown gracefully. This is what is logged on the console after the disk spin up message: ad8: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing request directly ad8: WARNING - SET_MULTI taskqueue timeout - completing request directly ad8: TIMEOUT - READ_DMA retrying (1 retry left) LBA=20047817 ad8: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES SET TRANSFER MODE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing request directly ad8: WARNING - SETFEATURES ENABLE RCACHE taskqueue timeout - completing request directly ad8: WARNING - SET_MULTI taskqueue timeout - completing request directly ad8: TIMEOUT - READ_DMA retrying (0 retries left) LBA=20047817 <rinse and repeat> I can only reproduce it when my gmirror volume is running. Any ideas? Thanks, Aragon
