Proxmox-Server 偶爾重啟

我剛剛提到我的 proxmox 系統在執行備份任務時不時重新啟動（bacula，而不是 proxmox-backup-system）。

有什麼想法嗎？

通常當某些東西偶爾重啟時，它不是作業系統，而是物理問題。

我會從電源開始。是好還是便宜？伺服器上是否有冗餘電源，或者是低端伺服器或台式機。電源是否過載？

有可能存在一堆磁碟，並且這些磁碟在執行備份時都在旋轉和搜尋，從而使功耗達到峰值。這可能會導致電源的一個特定軌道（又名電壓匯流排）過載，儘管整個 PSU 都很好。

例如，如果 +5V 上的最大功率為 20 安培，並且您有 10 個磁碟，每個磁碟的電流為 2.1 安培，那麼您將過載電源，它將關閉或重新啟動。
