在卷组中找不到逻辑卷

我需要增加尺寸centos_s0106ac9e17b4312300-root

我在尝试sudo lvextend -L +10G /dev/mapper/centos_s0106ac9e17b4312300-rootJESSE

但得到 Logical volume rootJESSE not found in volume group centos_s0106ac9e17b4312300.

逻辑卷称为root，而不是rootJESSE。它已安装，/mnt/centos_s0106ac9e17b4312300-rootJESSE但您需要使用 <vg_name>/<lv_name>for lvextend，而不是安装点，因此您需要运行

sudo lvextend -L +10G centos_s0106ac9e17b4312300/root

我还建议您--resizefs也使用调整文件系统的大小（否则您需要在使用（对于 XFS）或（对于 Ext4）lvextend调用之后执行此操作。xfs_growfsresize2fs

卷组中也没有 10 GiB 的可用空间，centos_s0106ac9e17b4312300因此该lvextend命令仍然会失败。您的驱动器上没有多余的空间sda，因此我不确定您的计划是什么。
