Hi,

 

Need some help here. My disk3 has developed some errors:

 

disk3 WDC_WD15EARS-00Z_WD-WMAVU1403399 36°C 1,465,138,552 161,291,456 3,506,713 6,642,178 9

 

Syslog (severall like this):

Notice the seven Current_Pending_Sector.

 

What should I do?

 

Thanks

 

Stop array, power down, and check (unplug and replug) all connections to the suspect disk. Reboot and then run a read only parity check. Then gather / post syslogs and smart report.
