A Proxmox disk that only the node's sensors report never raised a
temperature alert: CheckDiskHealth judges health and wearout only, and
unified evaluation covers TrueNAS disks, not PVE ones. Physical Disks
could read the disk Running Hot under the per-type thresholds while
alerts stayed silent, and whether a disk alerted depended on whether a
Pulse agent happened to run on the node.
The PVE disk poller now hands each disk's current reading to
CheckProxmoxDiskTemperature, which judges it by the same disk
temperature policy as agent and TrueNAS disks (DiskTempByType under the
agent Disk Temp default) under the disk's existing PVE alert reference.
A disk a still-reporting linked agent lists in its SMART report is the
agent's: CheckHost alerts on it and the PVE alert closes as moved to the
agent, so no disk alerts twice. A retained reading holds the alert,
an excluded device or a switched-off policy closes it, warnings wait the
same 300s stability window as other disk temperatures, a config save
re-judges the alert per disk type, and resource history owns its rows by
the disk's recorded identity like the health and wearout alerts.
