Parity errors on multiple drives?

Featured Replies

Hi,

 

A while ago my server did a scheduled parity check and I noticed one drive got 450 read errors and the next time I refreshed the parity check had stopped and the dot on the drive was red. So I thought that was an old drive and bought a replacement, installed it and started data-rebuild, but now I'm getting errors on other drives. Should I cancel the data-rebuild and do something before it finishes?

 

I'm on 4.7.

Anything common between those 4 drives, such as the same backplane or the same SATA card??

 

I'd be tempted to let it finish though I have doubts the rebuilt data will be much use.

They are not all connected to the same controller.

 

Now I cannot even get there through telnet or http?

 

Could or should I boot it and check the wires?

I booted and noticed that one of the sas cables was poorly connected, so now trying the parity check again.

I hope you mean the disk rebuild started again.

Yes, and this time it looks fine!  8)
