我有一個 Proxmox 集群，有兩個實體伺服器：pve 和 pve2。它們是相同的 Dell R710，具有 96GB 記憶體和 1TB (RAID-10)。由於某種我尚未確定的原因，pve2 將重新啟動。我已通過 iDRAC 檢查硬體日誌，沒有警報或錯誤。
我對 Proxmox 相當陌生，所以我不知道在通常的 Linux 地方之外哪裡可以找到錯誤日誌，例如系統日誌和訊息。
這是重新啟動時我的系統日誌的片段：（@ Dec 30 16:54:01）

關於它可能是什麼或我可以在哪裡檢查有什麼建議嗎？
答案1
這可能是硬體故障，最常見的是 RAM 故障。
在您的伺服器上執行 memtest 來找出答案。
