Seagate Iron wolf 8tb x8 raid z2





I have 8 8TB seagate iron wolf drives running in a raid z2 pool. I installed the brand new drives about a month ago. Yesterday I saw that my pool was degraded and that drive da7 was in error. freenas reported it had 325 read errors and 25 write errors. I ran a long smart test on the single drive and it completed with no errors. I took the drive offline and put it back online and now it says the pool is healthy. Does anyone have any advice on further testing? Should I just RMA the drive?

Any advice would be greatly appreciated!

Thanks!

Check the SMART raw values and the SMART error list.

Unless it was cabling related the drive is likely bad.
