Read errors during parity check

Featured Replies

Came home to a 20% complete parity check with 512 read errors on Disk 1.  A small number based on prior days (bad controller), but new nonetheless.  System has been running stable for a few days using an LSI 9211 and onboard SATA (Intel and Asmedia).  

 

SMART report and diags attached.

 

I'm tempted to just stop the parity check, power down the server, and re-seat cables etc.  This controller/cable combo has been running 100% solid for over a year in a previous server.  The disk is in a new iStarUSA 5-in-1 cage, I have two others and have never had issues with the cages or backplanes.  Disk is relatively new.

 

Advice welcome.

That's what I recommend, but replace or swap cables with another disk, just to rule them out if same thing happens.

Unfortunately its a break-out cable from the LSI 9211, but putting it on another disk seems reasonable.

 

As an aside, or perhaps not, when the server came back up, one of the spinners I have outside of the array was "missing."  I powered back down and checked cables -- all appeared well, however its certainly possibly something was bumped just slightly when I went in the first time.

 

Still, I am now questioning my power supply.  Its a Corsair TX 750, but coming up on 10 years old.  I know power supplies lose efficiency over time, but can they also output reduced power?  I have 16 spinners, 1 SSD, and an i5 in the system.  Figure 750w should be enough, but I'm not sure how many 12v rails this PS has.  Might be time to pick up a new power supply just to rule that out completely....

Now I have read errors on disk 7..... server is simply sitting idle.

 

Both read error disks are on the same (known good, at least up until now) LSI controller, and both are using different breakout cables.  

 

I am going to put the controller in another PCIe port to rule that out.

It is, but 10 years can take a toll
