在 PVE(Debian) 下使用 memtester 檢測記憶體

因為最近更換電腦, 透過線上購物買記憶體安裝, 開機後都正常, 但想完整測試記憶體是否都沒問題, 但透過 PVE 安裝開機 USB 的 memtest 選項卻無法正常進行測試, 所以在安裝好 PVE 後, 找在 PVE 底下測試記憶體的方式.

• 測試環境 :
  • PVE 5 :

    Kernel Version Linux 4.15.18-21-pve #1 SMP PVE 4.15.18-48 (Fri, 20 Sep 2019 11:28:30 +0200)
    PVE Manager Version pve-manager/5.4-13/aee6f0ec

  • PVE 6 :

    Kernel Version Linux 5.0.15-1-pve #1 SMP PVE 5.0.15-1 (Wed, 03 Jul 2019 10:51:57 +0200)
    PVE Manager Version pve-manager/6.0-4/2a719255

• 安裝 memtester

  apt-get install memtester

• 檢測記憶體 Exp. 檢測 2G 重複 3 次

• 如果記憶體有問題, 在前面幾個測試項目就會出現
