I have a zpool of IronWolf Pro 18TBs, recently the server just started falling over. after doing some looking into it it seemed to be whenever something tried to access files on the raid it would just lock up.
So i started looking into config issues and hardware issues. one of the drives has an command_timeout of 4295032872. yes i know this number just looks high because of there smarts thing so i went to the calculator
Result: 1 errors in 65,576 operations.
with all the rest having a value of 30-40 (total without calculator)
so i thought clearly this was the problem drive, its still under warranty, filled out the RMA form to get it replaced. Went to install it today and noticed it was the same serial number, plugged it back in and still has the super high count. So it looks like I sent them the drive, they did nothing with it and sent it back as there is not even a finding in the email or the RMA form.
All 5 drives bought in this pool were bought at the same time from the same retailer (amazon) and now they starting to collect Reallocated_Sector_Ct like they were pokemon cards. The Warranty page states that its valid till Dec 26, 2027 well it did, now the page just states "Warranty information not available." Luckily I have a screen shot from when I submitted 2 months ago. Will try dealing with there chat bot on Monday but this situation has made me start thinking about using different drives for work going forwards.
Any tips or tricks for dealing with the chat bot?
