Read Errors On the array

[Troussdesoin]

Hello Guys,

 

Some time ago, i had read Errors on the array. But it was BTFRS errors and i removed the cache drive and it stopped spewing errors.

 

But tonight, when i came home, it says it had found read errors. It it bad? Should i buy new drives?

 

Thanks a lot

Disk2 appears to be failing, run an extended SMART test.

 

P.S. next time please post the single diags zip file.

[Troussdesoin]

Ok, i'm running it on Disk 2, but DIsk 1 is also saying that there are some errors

 

Could it be software related?

[JorgeB]

Also start a test for disk1, it can't be software, but it can be a different hardware issue, though it's logged as an actual disk problem for both disks.

[Troussdesoin]

Hum, the Two tests completed without Error , here are the reports.

 

It doest not seem like there is a major problem. What do you think?

Disks are showing some SMART warnings, but this type of read errors can be intermittent, run another check (non correcting), also keep an eye on these attributes, if they continue to increase there will likely be more errors soon.
