Getting errors

[farshidhss]

Hello,

I'm recently starting to get errors during scrubbing. Looking at zpool status I get this:

Code:

  pool: Farshid-NAS
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
    attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
    using 'zpool clear' or replace the device with 'zpool replace'.

errors: No known data errors

I have recently upgraded the memory and added a Dell H310 HBA, is it possible that this is caused by the upgrade? Appreciate if you give me some suggestions on how I can further investigate this.

That could be caused by the HBA. Is it in IT mode ?

I'm not totally sure. My "dmesg | grep mps" gives:

It's in IT mode.
Could still be faulty
What drives are these ?

 

[farshidhss]

These are Seagate Ironwolf:
Model Family: Seagate IronWolf
Device Model: ST4000VN008-2DR166

I did a memtest86+ and found errors in Ram, I changed the memory and confirmed that new memory has no errors after a few pass of memtest. Now going to see if I get checksum errors again while scrubbing.
