We recently removed a disk from Proxmox and started receiving SMART errors with the info FailedReadSmartData. All that was required was to edit the smartd.conf file as follows:
nano /etc/smartd.confComment out the line that looks similar to this:
DEVICESCAN -d removable -n standby -m root -M exec /usr/share/smartmontools/smartd-runnerAdd monitoring for the remaining disks as follows:
/dev/sda -m root -M exec /usr/share/smartmontools/smartd-runner
