Help with errors in storage pool

Could be RAM as well.

Hadn't thought about that. I can boot into memtest and get a test started.

[u/ht3k → u/onelargeracoon]

memtest86 doesn't catch errors under stress, only if the RAM is pretty much dying.

You want something like https://github.com/stressapptest/stressapptest

or mprime95 blend test. Many people fail to detect defective memory because it a lot of the time some memory fails only while it's under load. Memtest86+ doesn't provide stress memory testing, it's only a simple mem checker.

That's excellent information, I'll look into this. Thanks

Given that you have checksum errors across all drives, could it be an issue with your storage controller? Maybe bad cables?

[u/onelargeracoon → u/roubent]

I have replaced cables and tried it with an HBA card as well as using the onboard SATA. Still persists.

This could just be raidz's "I don't know which disk the corrupted data was on, so I'll charge one checksum error to every disk it could have been on" at work.

power supply can affect all drives at once.

Do you have an HBA? They can run hot as well.

[u/onelargeracoon → u/edthesmokebeard]

I did have an HBA, but I had a 120mm fan pointed at it and that seemed to keep it decently cool. It sounds like I might need to swap PSUs and see if that helps.

I had issues with my zfs pool until I changed each drive to performance mode...could be worth a look. They were I/O errors though.

[u/onelargeracoon → u/rehpotsiirhC]

I'll keep that in mind, thanks.

I got this issue figured out. Explanation shared with original post.

After dealing with ram issues over the years, only use ECC ram in my ZFS storage. Glad you got it figured out!
