Can’t initialize physical volume “/dev/sdb” of volume group “xxx” without -ff /dev/sdb: physical volume not initialized.

解决方案：

sudo pvcreate -ff -y /dev/sdb1

Can’t open /dev/sdb1 exclusively. Mounted filesystem?

解决方案：

查看物理卷（PV）的详细信息

sudo pvdisplay

ll /dev/mapper/

sudo dmsetup remove myvg1-mylv1

xfs_growfs: /data is not a mounted XFS filesystem

sudo xfs_growfs /dev/myvg1/mylv1

不知道LV Path先查询

sudo lvdisplay

解决：

VG是VG Name，可以通过sudo pvdisplay命令查询

sudo vgreduce --removemissing VG
