My Solaris messages log suddenly is full of errors.. Seems like a drive is dying. At least, that is what smartd seems to be reporting:
Feb 14 03:34:23 nas smartd: [ID 702911 daemon.crit] Device: /dev/rdsk/c7t6d0s0 [SAT], 10 Currently unreadable (pending) sectors Feb 14 03:34:23 nas smartd: [ID 702911 daemon.crit] Device: /dev/rdsk/c7t6d0s0 [SAT], 5 Offline uncorrectable sectors
However, smartctl disagrees.
./smartctl -a /dev/rdsk/c7t6d0 === START OF READ SMART DATA SECTION === SMART overall-health self-assessment test result: PASSED
And iostat doesn't seem to mind either:
root@nas:/opt/csw/sbin# iostat -E sd12 sd12 Soft Errors: 3 Hard Errors: 0 Transport Errors: 0 Vendor: ATA Product: WDC WD20EARS-00M Revision: AB51 Serial No: WD-WCAZA7310157 Size: 2000.40GB <2000398934016 bytes> Media Error: 0 Device Not Ready: 0 No Device: 0 Recoverable: 3 Illegal Request: 2 Predictive Failure Analysis: 0
I guess we'll see in the next few days.
