xfs_growfs: / 不是已安裝的 XFS 檔案系統

我有一個虛擬專用伺服器，剛剛升級了硬碟空間，但無法擴展我的驅動器，至少我不知道如何擴展。

root@localhost:~# xfs_growfs /
xfs_growfs: / is not a mounted XFS filesystem

讓我困惑的是，這裡說它確實有 160GB，/dev/sda2 999424 335544286 334544863 159.5G 8e Linux LVM但當我檢查它時卻沒有：

我想知道是否需要重新啟動伺服器？

分區類型為左心室容量這表示您的根分割區是一個邏輯磁碟區 (LV)。邏輯磁碟區屬於由一個或多個實體磁碟區 (PV) 組成的磁碟區組 (VG)。嘗試這個：

vgdisplay -v
# Note the following values:
# PV Name, e. g. '/dev/vda3' (physical volume)
# LV Path, e. g. '/dev/ubuntu-vg/ubuntu-lv' (logical volume)

growpart <DISK> <PARTITION_NUMBER> # e.g. 'growpart /dev/vda 3'
pvresize <PV_NAME> # Resize the physical volume
lvresize <LV_NAME> -l 100%VG # Logical Volume should get the whole space of the Volume Group
resize2fs <LV_NAME> # Resize the file system (e. g. ext4)
