Multiple Offline uncorrectable sectors

I'm finding this odd, or just shear bad luck with our drives. But we have a cluster of 8 proxmox hosts, and out of the 8, 2 hosts constantly start to show errors. We've replaced the drives with new ones, and a few months later we get reports of these errors again. Anyone know if there are some parameters for smartd that I can look at? Firmware is all at the latest version, along with BIOS. I'm just finding it odd that it is only 2 of the servers out of the bunch, and all have the same type and brand of SSD's.

Maybe check with smartctl -a /dev/sda if there is more wrong? Maybe run a short and long test? And check journalctl for more I/O errors around the same time.
Maybe switch their place in the server rack with some of the other servers? Maybe it's a (location specific) vibration that the drives can't handle? Or put the new drives in another server and the known to be good drives of that server in the two problematic ones?

Nothing looked out of the ordinary within journalctl. Tried the long and short, but just came up as passed, but had uncorrectable error counts. Nothing shows on the server SMART logs, only within Proxmox.

I only just noticed your drives are SSDs. It's possible that the attribute does not represent offline uncorrectable sectors like it once did for HDDs. SMART attributes are not standardized and smartd is not perfect. Maybe try to find out what the attribute means for these particular drives by contacting Dell support and update the smartd configuration accordingly (or tell it to ignore it).

EDIT: Looks like other people also run into this: https://forum.proxmox.com/threads/s...but-no-smart-error-on-test.139489/post-623192
