My not too old Crucial 4TB SSD running Proxmox Backup Server (Debian) regularly returns email telling me there is 1 bad sector pending.

I'm not sure if it is causing the ext4 fs to become read-only, and hard crash the server, unpredictably.

Below is the output from smartctl.

Should I get this SSD replaced? It is under 5-year warranty.

No, bad sector pending is handled by drive firmware and you don't need new disk yet.
You should run "smartctl -t short /dev/sda" weekly and checkout values on ssd/nvme with "-x" to see wearout also (Xtrem output but for hdd with "-a" is ok).

But it is causing hard crashes... i'll try "dmesg" when it happens, or when fs becomes read-only.
