I've had a drive redball again.  It redballed a couple of weeks back but I managed to get it back up on the array and hoped it was just a hiccup, alas I think it's dying.  (log attached if anyone wants to have a look).

 

Am I right that I just need to pull out the redaballed drive, replace it with another of the same capacity, start unraid and begin a rebuild ?  Once the rebuild is complete I will have the data back ?

 

If I've misunderstood, please let me know. I'd really like to have the replacement done this evening and let the rebuild run over night.

 

TIA

That's it, other than to research why the disk was taken out of service.  (a write failed, obviously, but did the drive lose power? or was it a communication error or timeout?)

 

If a intermittent drive tray is involved, or poor quality power splitter, or intermittent SATA cable, then the replacement will go offline too soon after installation.

 

Good luck.  Can't hurt to re-seat all the connections involved (both power and data)

 

If you have a parity disk installed (mandatory for a data re-construction) then you'll be protected once more from an additional drive failure.  You can still access the "failed"' disk while it is being simulated by parity and the remaining data drives.

 

 

Thanks.  I couldn't get the redballed drive back up like I could a couple of weeks ago, even after reseating all cables.

 

No worries, replaced it with another 2tb drive I keep as a spare and the data-rebuild is currently 20% through.

I am looking at replacing an existing drive with a different one. Will this be the same procedure on known good drive? Is there any risk of losing data aside from while rebuilding,  another drive fails?
