And a “badblocks” command on some of the related hard drive reports that failed sectors found, while others reports no, false-positive. Any one can give me suggestions or hints?<o:p></o:p> <o:p> </o:p> Thanks a lot.<o:p></o:p> <o:p> </o:p> ……<o:p></o:p> Host: arc242<o:p></o:p> arc242: Apr 29 13:51:32 arc242 kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }<o:p></o:p> arc242: Apr 29 13:51:32 arc242 kernel: hdb: dma_intr: error=0x01 { AddrMarkNotFound }, LBAsect=38613129, sector=38613064<o:p></o:p> arc242: Apr 29 13:51:36 arc242 kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }<o:p></o:p> arc242: Apr 29 13:51:36 arc242 kernel: hdb: dma_intr: error=0x01 { AddrMarkNotFound }, LBAsect=38613129, sector=38613064<o:p></o:p> arc242: Apr 29 13:51:43 arc242 kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }<o:p></o:p> arc242: Apr 29 13:51:43 arc242 kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=38613129, sector=38613064<o:p></o:p> arc242: Apr 29 13:51:43 arc242 kernel: end_request: I/O error, dev 03:41 (hdb), sector 38613064<o:p></o:p> arc242: Apr 29 13:51:49 arc242 kernel: hdb: dma_intr: status=0x51 { DriveReady SeekComplete Error }<o:p></o:p> arc242: Apr 29 13:51:49 arc242 kernel: hdb: dma_intr: error=0x40 { UncorrectableError }, LBAsect=38613129, sector=38613064<o:p></o:p> arc242: Apr 29 13:51:49 arc242 kernel: end_request: I/O error, dev 03:41 (hdb), sector 38613064<o:p></o:p> <o:p> </o:p> Host: arc292<o:p></o:p> arc292: Apr 29 04:02:27 arc292 kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }<o:p></o:p> arc292: Apr 29 04:02:27 arc292 kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=239379157, high=14, low=4498133, sector=331888<o:p></o:p> arc292: Apr 29 04:02:27 arc292 kernel: end_request: I/O error, dev 03:0b (hda), sector 331888<o:p></o:p> arc292: Apr 29 04:02:29 arc292 kernel: hda: dma_intr: status=0x51 { DriveReady SeekComplete Error }<o:p></o:p> arc292: Apr 29 04:02:29 arc292 kernel: hda: dma_intr: error=0x40 { UncorrectableError }, LBAsect=239379157, high=14, low=4498133, sector=331888<o:p></o:p> arc292: Apr 29 04:02:29 arc292 kernel: end_request: I/O error, dev 03:0b (hda), sector 331888<o:p></o:p> <o:p> </o:p> ...... blahblah…<o:p></o:p> <o:p> </o:p> I tried to run “badblocks” on the boxes to test whether there are real hardware problems, then I got some of them really reports problems, and some of them NOT.
