On SCSI drives one could look at the bad block lists to see if it was growing to know if a drive was getting sick. In the wee hours of the morning one of my Hitachi HDS722516VLSA80's got sick: Mar 17 03:04:39 Grumpy kernel: ad4: TIMEOUT - READ_DMA retrying (2 retries left) LBA=282857146 Mar 17 03:04:39 Grumpy kernel: ad4: FAILURE - READ_DMA timed out Mar 17 03:04:39 Grumpy kernel: GEOM_VINUM: subdisk vinum0.p0.s0 state change: up -> down Mar 17 03:04:39 Grumpy kernel: GEOM_VINUM: plex vinum0.p0 state change: up -> down "atacontrol info" says SMART is enabled. So what does this do for me? Has the drive exhausted its supply spare blocks and can no longer repair itself? While we are at it, the size of an LBA is 512 bytes? Putting the problem block above at about 144G? -- David Kelly N4HHE, dkelly@HiWAAY.net ======================================================================== Whom computers would destroy, they must first drive mad.
