I am running UnRAID 6.9.2. I was planning on upgrading this weekend, but my monthly disk check reported read errors on my parity drive. My SMART report does not appear to show any errors. I have not shut down, the only thing I did was run another parity check, which passed with no errors. Any help would be greatly appreciated. 

 

Thanks in advance.

Error 2 [1] occurred at disk power-on lifetime: 17515 hours (729 days + 19 hours)

 

Reseat the cabling.

 

Also, trimming every hour is going to decrease the lifetime of the SSD.  Once a week is more than sufficient.

Thanks for the fast response. Since you said more than sufficient, I have set the trim to once a month. If I should move it to once a week, I'm ok with that too.

 

I am currently in the process of running an extended test. As soon as that finishes, I will power down and reseat the cables on the device.

 

Again, thank you for responding so fast.

My Extended test finished. There were no errors found. This morning, I powered off the server and reseated the cables on the drive indicated. I did notice that the power connector right next to the one connected to the drive with issues has a 4-pin molex adapter for a fan controller. I'm not sure if that is the cause or not, but if it happens again, I will start looking for an alternative there. After the server came up and I was able to ensure that the issue was resolved at least for the time being, I backed up my flash drive and upgraded to the newest version of unRAID. This was the plan before I started getting the errors. So far, so good. Thanks for the assistance, @Squid!
