我需要一些幫助來理解 Journalctl 的輸出,因為它與系統崩潰/凍結有關

我最近遇到了很多死機和奇怪的突然重新啟動的情況。大多數情況下,這種情況發生在我使用串流媒體時。定格無限循環持續(約)1 秒的音訊。我以為我已經找到並解決了好幾次了,但每次都錯了。

我嘗試在啟動期間運行 memtest,但它凍結在 15%、30% 或 40%,具體取決於我選擇的設定。我知道某些 BIOS 和主機板可能並且確實會發生這種情況。

我運行 SMART 並看到一些標記為預先失敗的功能。 (我計劃購買一個較新的驅動器,並在有能力的情況下將舊驅動器的內容複製到其替換驅動器上)。

下列的這個答案我的問題,我跑了sudo journalctl -b -1 -e

我的理解是從這個問題UFW BLOCK 表示連線被阻止。它在輸出的尾部出現很多(我將輸出重定向到文字檔案)。

在這些本機 IP 位址上,254 是我的路由器,103 是我的 PC

我正在查看文件的正確部分嗎?

這裡有崩潰原因線索嗎?

我還可以去哪裡看看?

進一步更新:所以,我打開我的電腦,並從每個 RAM 上的 GRUB 選單中使用 Memtest68+ 5.01。他們都通過了。花了幾個小時。我不急於再次這樣做。

更新頂部進一步更新:我還查看了 UFW BLOCK 記錄,並明確允許我的網路上更常見的廣播。因此,這些 UDP 錯誤不太可能成為持續存在的問題。

進一步進一步更新:我整理了大部分 UDP 區塊,最後一次運行結束如下:

更新#1:

memtest運轉時凍結。懷疑 RAM 損壞,或需要將 RAM 重新插入插槽。 RAM 位於插槽 DIMM0-3 中。卸下 DIMM1-3 並重新測試memtest。如果memtest執行沒有錯誤,則在插槽 DIMM1 中重新新增一條 DIMM,然後重新測試,依此類推。

我以為硬碟太熱了。原來這些是索引值

答案1

記憶體測試

您可能遇到硬體問題。

https://www.memtest86.com/並免費下載/運行它們memtest來測試您的記憶力。至少完成一次所有 4/4 測試,以確認良好的記憶力。這可能需要幾個小時才能完成。

交換

除非您休眠,否則您的交換分區太大。我們將用 4G /swapfile 取代它。

筆記rm:和命令使用不當dd可能會導致資料遺失。建議複製/貼上。

在裡面terminal...

sudo swapoff -a           # turn off swap
sudo rm -i /swapfile      # remove old /swapfile

sudo dd if=/dev/zero of=/swapfile bs=1M count=4096

sudo chmod 600 /swapfile  # set proper file protections
sudo mkswap /swapfile     # init /swapfile
sudo swapon /swapfile     # turn on swap
free -h                   # confirm 16G RAM and 4G swap

sudo -H gedit /etc/fstab使用或編輯 /etc/fstab sudo pico /etc/fstab

確認 /etc/fstab 中的此 /swapfile 行...並確認沒有其他「交換」行...在此行中使用空格...確認沒有製表符...

/swapfile  none  swap  sw  0  0

筆記:刪除其他現有的交換線。用於gparted刪除/dev/sda5。


reboot                    # reboot and verify operation

更新#2:

您的 sdc 驅動器似乎有一個或多個壞塊。我們來繪製一下地圖吧...

注意:不要中止壞塊掃描!

注意:不要對 SSD 進行壞塊操作

注意:首先備份您的重要文件!

注意:這將需要幾個小時

注意:您可能有待處理的硬碟故障

在「嘗試 Ubuntu」模式下啟動至 Ubuntu Live DVD/USB。

terminal...

sudo fdisk -l# 辨識所有「Linux 檔案系統」分割區

sudo e2fsck -fcky /dev/sdXX# 唯讀測試

或者

sudo e2fsck -fccky /dev/sdXX# 無損讀/寫入測試(受到推崇的)

-k 很重要,因為它保存先前的壞塊表,並將任何新的壞塊添加到該表中。如果沒有 -k,您將丟失所有先前的壞塊資訊。

-fccky 參數...

   -f    Force checking even if the file system seems clean.

   -c    This option causes e2fsck to use badblocks(8) program to do
         a read-only scan of the device in order to find any bad blocks.
         If any bad blocks are found, they are added to the bad block
         inode to prevent them from being allocated to a file or direc‐
         tory.  If this option is specified twice, then the bad block scan
         will be done using a non-destructive read-write test.

   -k    When combined with the -c option, any existing bad blocks in the
         bad blocks list are preserved, and any new bad blocks found by
         running badblocks(8) will be added to the existing bad blocks
         list.

   -y    Assume an answer of `yes' to all questions; allows e2fsck to be
         used non-interactively. This option may not be specified at the
         same time as the -n or -p options.

更新#3:

刪除 /dev/sda5 後,您的 HDD 上留下了 28G 未分配的空間。您可以將該空間新增至 /dev/sda1。

確保您對重要的 Ubuntu 檔案有良好的備份,因為此過程可能會損壞或遺失資料。

請記住以下幾點:

  • 始終以發出交換在任何已安裝的交換分割區上,並透過發出交換在同一個交換分割區上

  • A移動將滑鼠指標指向分區的中心並用手形遊標向左/向右拖曳來完成

  • A調整大小透過使用方向箭頭遊標將分區的左/右側拖曳到左/右來完成

  • 如果任何分區不能移動/調整大小以圖形方式,您可能必須手動輸入所需的特定數字資料(除非我指示您這樣做,否則不要這樣做)

  • 你開始任何移動/調整大小右鍵單擊主視窗下部窗格中的分區,然後從彈出式選單中選擇所需的操作,然後在新視窗中完成該操作移動/調整大小窗戶

請執行下列操作...

筆記:如果該過程不完全按照我概述的那樣進行,停止立即且不要繼續。

  • 在“Try Ubuntu”模式下啟動至 Ubuntu Live DVD/USB
  • 開始gparted
  • 刪除/dev/sda2 擴充分區
  • 調整大小/dev/sda1 的右側一直到右側
  • 點擊“應用”圖標
