我在分配給伺服器的一些空間時遇到問題，我需要向分割區 /store 新增 1TB
df -h 顯示

所以 1TB 未分配，但我找不到在哪裡調整分割區大小
我嘗試使用 resize2fs、xfs_growfs、fdisk、parted 但沒有任何反應
有什麼可能的解決辦法嗎？謝謝
答案1
這裡仍然有一些猜測，但是...
看起來分割區 7、6 MB 檔案系統未使用。如果這是正確的，我會刪除它並建立一個新分割區。理想情況下，您可以將現有分割區 5 和 6 移至磁碟末尾，以便可以使用pvresize目前分割區store，但我沒有為您提供命令列演練。
如果您能夠使用rescue-cd並且可以承受伺服器上的停機時間，您可以啟動rescue-cd並使用gparted圖形化前端來移動它們（命令列工具放棄了對移動一段時間的支援）前）。
如果無法選擇停機，最簡單的方法是在可用空間中建立新分割區，並將其新增至現有磁碟區組。假設您刪除了微小的 #7，並用 1TB 重新建立了它。 （如果正在使用，請建立一個新分割區 #8 並在下面的範例中使用它）。
vgextend storerhel-store /dev/sda7
現在， Avgdisplay應顯示卷組的可用盤區大小為 1TB（空閒 PE）。之後你可以
lvextend -r -l +<Available Size> /dev/mapper/storerhel-store
