Smartctl Offline_Uncorrectable in SSD

[rlljorge]

Hello !

I am receiving a lot of email about Offline_Uncorrectable in my SSD, in different servers and multiple devices.

The following warning/error was logged by the smartd daemon:

Device: /dev/sdc [SAT], 16 Offline uncorrectable sectors

This look like a bug the ssd is not too old and happens in multiple servers and devices.

Can I ignore this mensagens or I need some type adicional check ?

Device is: Not in smartctl database 7.3/5577

I would start with a: update-smart-drivedb: [1] on the host(s). Your disk model is (meanwhile) present; at least in the latest version: [2].
I also would run a long SMART-test in any way.

But all this is not specific to PVE or Proxmox products in general. So, if you suspect some kind of bug, I suggest to reach out to the Smartmontools: [3] and/or disk manufacturer support channels.
