Errors during disc rebuild

[dwilliams]

Hi,

 

I did some reading through other similar posts, but I can't quite figure out what is wrong. I went to upgrade one of my data drives from 4TB to 8TB (just increasing the space, not because of failure). Parity drive is 8TB. I have never had a drive error or issue before, looked at how the upgrade was going and now I am facing (72% done rebuild):

 

Errors

- Parity drive shows 10,000,000 reads, 196 writes, and 69,000,000 errors?

- Disc 1 shows 10,000,000 reads, 16 writes, and 69,000,000 errors?

- Disc 2 shows 10,000,000 reads, 42 writes, and 69,000,000 errors?

- Disc 3, Disc 4 (data build disc) and Disc 5 all have zero errors. All are showing green on the left side status

 

Smart Check Unavailable

- I tried running a SMART report on Drive 1 or Drive 2, but it won't load any, and down in attributes says "A mandatory smart command failed". I tried changing the SMART notification value to raw and then back to default based on other threads but no luck

 

 

I have the parity check paused, whats my best course of action? Finish it, reboot and see what errors show up? Finish and swap out new parity, disc 1 and disc 2 drives? Abort and put original Disc 4 back in? Is my parity corrupted and overwriting other good data on my drives?

 

*I should note, rebuild process had no errors at the 50% mark when I checked, only started providing errors recently.

Please post the diagnostics: Tools -> Diagnostics

Here are the diagnostics. I ended up completing the parity build since it was at 70% to see if the process would at least build the info on the disc.

This is a fairly typical problem with the SATA controller on Ryzen boards, there are reports that updating to the latest beta helps due to the much newer kernel, disabling IOMMU should also help if it's not needed.

That's OK but note that the rebuilt disk will be corrupt once the errors started.

So best course of action would be to restore the original 4TB drive, update the Ryzen board, and try to re-upgrade to the 8TB disc again?

Probably the easiest way.

Thanks for the advice @johnnie.black - got the drive installed and upgraded.
