首先检查是否存在devices文件：
ls -l /etc/lvm/devices/
如果该目录存在，我们可以尝试重新生成devices文件：
rm -f /etc/lvm/devices/*
vgimportdevices -a
检查
[root@localhost devices]# pvscan
Please remove the lvm.conf filter, it is ignored with the devices file.
PV /dev/nvme0n1p3 VG cs lvm2 [<249.00 GiB / 0 free]
Total: 1 [<249.00 GiB] / in use: 1 [<249.00 GiB] / in no VG: 0 [0 ]
[root@localhost devices]# vgscan
Please remove the lvm.conf filter, it is ignored with the devices file.
Found volume group "cs" using metadata type lvm2
[root@localhost devices]# pvs
Please remove the lvm.conf filter, it is ignored with the devices file.

[root@localhost devices]#
让我们检查一下分区情况：
[root@localhost devices]# parted /dev/nvme0n1 print
型号：VMware Virtual NVMe Disk (nvme) 磁盘 /dev/nvme0n1：290GB 扇区大小 (逻辑/物理)：512B/512B 分区表：gpt 磁盘标志：pmbr_boot
编号 起始点 结束点 大小 文件系统 名称 标志 1 1049kB 2097kB 1049kB bios_grub 2 2097kB 1076MB 1074MB xfs bls_boot 3 1076MB 268GB 267GB lvm
使用parted扩展分区到磁盘末尾：
parted /dev/nvme0n1 resizepart 3 100%
使用parted扩展分区到磁盘末尾：
[root@localhost devices]# parted /dev/nvme0n1 resizepart 3 100%
信息: 你可能需要 /etc/fstab。
[root@localhost devices]# partprobe /dev/nvme0n1
[root@localhost devices]# pvresize /dev/nvme0n1p3
Please remove the lvm.conf filter, it is ignored with the devices file.
Physical volume "/dev/nvme0n1p3" changed
1 physical volume(s) resized or updated / 0 physical volume(s) not resized
[root@localhost devices]#
很好，物理卷已经成功调整大小。现在让我们继续扩展逻辑卷：
lvextend -l +100%FREE /dev/cs/root
扩展文件系统：
xfs_growfs /dev/cs/root
验证
df -h
