Parity sync error reoccur after every test.

[TIE Fighter]

Hi. 

 

After parity sync error check there was 330 errors found. It started about 2 months ago when errors was found and have been increased since. So far about 10 tests have been made. 

Have been reading through the forum threads for a solution but I would like some guidance in this matter. 

 

I have checked all sata Cables and the hot swap Bays, all secured and in position. 

 

Smart test on all drives without any errors. 

 

Memtest86 ran for a couple of hours, no errors found

Run a couple of non correcting parity checks and post new diags after that (before rebooting) but first check/replace cables on disk2.

So I replaced the sata cable for disk 2

And run two non correcting parity checks. 

 

1st check gave 5 errors

2nd check gave 2 errors

Based on that bad RAM would be my main suspect, run memtest.

3rd non correcting parity check gave 1 error. 

So the errors are almost gone now since i replaced the sata cable. 

Can i do a 4th parity check before I do a memtest cause I have already made that in the past and the memory are new.

The cable wasn't the problem, the different number of errors (on different sectors) suggest very strongly that there's a hardware problem, like bad RAM.

Finished 4th non correcting parity sync error check with 0 errors. 

 

Will this mean that all is okay from now and I can stop investigate and rest this case. 

 

Att: diagnostics from last parity check. From here the server have been restarted

Unlikely the problem went away on its own, you'll probably get more errors on future checks.

Now i discovered warnings and errors in the disk log info for disk 3, but I dont really understand what they mean.

That looks like a connection issue, check/replace cables on disk3.
