linux硬碟分割槽及掛載

由於時間限制，本人僅在centos 8下測試通過，理論上適用於幾乎所有的linux發行版。輸入df h檢視當前系統的硬碟容量使用情況，當前我的伺服器上空間總容量看起來只有20g，然而當輸入lsblk檢視當前系統上所有的磁碟列表時，從輸出結果中可以看出，除了乙個vda的20g的硬碟外還有乙個vdb的6...

Linux新增硬碟分割槽及掛載

1 分割槽 fdisk命令，l 檢視所有分割槽 fdisk dev sdb1 進行分割槽，過程比較簡單，根據提示即可，注意最後要儲存生效 2 格式化 mke2fs命令，mke2fs t ext4 dev sdb1 格式化 dumpe2fs命令，dumpe2fs dev sdb1 檢視分割槽檔案系統 ...

linux 硬碟分割槽及行動硬碟掛載

1.linux 硬碟分割槽 在 linux 中規定，每乙個硬碟裝置最多能有 4 個主分割槽 其中包含擴充套件分割槽 構成，任何乙個擴充套件分割槽都要占用乙個主分割槽號碼，也就是在乙個硬碟中，主分割槽和擴充套件分割槽一共最多是 4 個。對於早期的 dos 和 windows windows 2000 ...
