ZFS makes this completely trivial except for the "beeps and lights a led" part

• ahofmann 2mo ago
  To be fair, the "beeps and lights a led" part is very important in case of a dead disk in an array. The only time, I disrupted a service in production for longer than a few hours was when I didn't get the email of a degraded raid 1 array and the second disk died a few weeks later.

  smartmontools makes this trivial and can email you which might be better than beeping and lights if you’re not always near your server. I use that plus smartctl_exporter so I can do metrics and alerting off that.

    That’s awesome. But a guide that does not include a howto for alerting (such as the one linked) is incomplete.

    smartmontools misses data corruption at the drive layer, as it trusts the drives to report faithfully. "In hashes I trust"

      Does Synology with its beeps and bops catch that?
    • shric 2mo ago
      Yeah, for that I use periodic scrubs and zfs event daemon
