I am trying to understand the various error conditions reported by iostat. I noticed during a recent scrub that my transport errors were increasing. However, after a fair amount of searching I am unsure if that indicates a drive failure or not. I also have a lot of illegal request errors. Not sure if those are indicative of any sort of "real" failure.
Here is the output from iostate -E: iostat -E sd3 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: ST9160412AS Revision: LVM1 Serial No: Size: 160.04GB <160041885696 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd4 Soft Errors: 0 Hard Errors: 5 Transport Errors: 49 Vendor: ATA Product: SAMSUNG HD103SJ Revision: 0001 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 5 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd8 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: SAMSUNG HD103SJ Revision: 0001 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd10 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: SAMSUNG HD103SJ Revision: 0001 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 5998 Predictive Failure Analysis: 0 sd12 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: ST9160412AS Revision: LVM1 Serial No: Size: 160.04GB <160041885696 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 34 Predictive Failure Analysis: 0 sd13 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: SAMSUNG HD103SJ Revision: 0001 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 5998 Predictive Failure Analysis: 0 sd14 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: SAMSUNG HD103SJ Revision: 0001 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 5998 Predictive Failure Analysis: 0 sd16 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: SAMSUNG HD103SJ Revision: 0001 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 sd19 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: WDC WD10EACS-00Z Revision: 1B01 Serial No: Size: 1000.20GB <1000204886016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 0 Illegal Request: 0 Predictive Failure Analysis: 0 Here is the output in a more readable, but less detailed form from someone's zfs-stats.sh script: ./zfs-stats.sh Disk Vendor Model Serial Firmware Totl Soft Hard Trns Meda NotR NoDv Rble Ilgl Fail ZPool c6t4d0 0 0 0 0 0 0 0 0 0 0 rpool c6t7d0 SAMSUNG HD103SJ S246JDWZ408066 1AJ10001 59 0 5 49 0 0 5 0 0 0 tank c4t17d0 SAMSUNG HD103SJ S246JDWZ408064 1AJ10001 0 0 0 0 0 0 0 0 0 0 tank c10t2d0 SAMSUNG HD103SJ S246JDWZ408074 1AJ10001 5998 0 0 0 0 0 0 0 5998 0 tank c10t4d0 34 0 0 0 0 0 0 0 34 0 rpool c10t5d0 SAMSUNG HD103SJ S246JDWZ408065 1AJ10001 5998 0 0 0 0 0 0 0 5998 0 tank c10t1d0 SAMSUNG HD103SJ S246JDWZ408075 1AJ10001 5998 0 0 0 0 0 0 0 5998 0 tank c4t18d0 SAMSUNG HD103SJ S246JDWZ408073 1AJ10001 0 0 0 0 0 0 0 0 0 0 tank c6t10d0 0 0 0 0 0 0 0 0 0 0 Are these transport errors anything to be worried about? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
