Red Ball Disk


Recommended Posts

I was running a parity check overnight. When I came back to it, this morning, the check completed with 768 errors on Disk 5 in my array. I was able to recover a portion of the syslog, but, not all :(

 

I also ran a SMART report:

Is this disk dead? Can I rebuild this disk from parity, or just replace it? I haven't been able to validate if there was a cabling failure yet. While I suppose that's possible, I'm still unsure how I'd proceed to rebuild this disk from parity, without actualy replacing it. Doing a New Config seems to be ill-advised, both on the tool page itself, as well as in this Forum. So, what should I be doing next?

 

Thanks For Your Time!
