彻底删除逻辑卷lvs

1、停止运行在lvs存储上面的应用，并确认是否还有占用对应存储的线程

bash 复制代码

[root@ip-172-31-26-146 ~]# docker stop kuboard
kuboard
[root@ip-172-31-26-146 ~]# lsof +D /data/lvs
[root@ip-172-31-26-146 ~]#

2、卸载目录路径

bash 复制代码

[root@ip-172-31-26-146 ~]# vim /etc/fstab 
[root@ip-172-31-26-146 ~]# umount /data/lvs

3、查看现有硬盘及挂载情况

bash 复制代码

[root@ip-172-31-26-146 ~]# lsblk

└─vg_data-lv_data 253:0    0  60G  0 lvm  
[root@ip-172-31-26-146 ~]# df -h

bash 复制代码

[root@ip-172-31-26-146 ~]# lvs

[root@ip-172-31-26-146 ~]# lvremove /dev/vg_data/lv_data
Do you really want to remove active logical volume vg_data/lv_data? [y/n]: y

5、删除vg

bash 复制代码

[root@ip-172-31-26-146 ~]# vgremove vg_data
  Volume group "vg_data" successfully removed
[root@ip-172-31-26-146 ~]# vgs
[root@ip-172-31-26-146 ~]#

6、删除pv

bash 复制代码

[root@ip-172-31-26-146 ~]# pvremove /dev/sdb

LVM 结构已经被彻底删除

查看删除lvs后对应的存储卷

bash 复制代码

[root@ip-172-31-26-146 ~]# lsblk
NAME          MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
nvme0n1       259:0    0  40G  0 disk 
├─nvme0n1p1   259:1    0  40G  0 part /
├─nvme0n1p127 259:2    0   1M  0 part 
└─nvme0n1p128 259:3    0  10M  0 part /boot/efi
nvme1n1       259:4    0  15G  0 disk

nvme4n1       259:7    0  15G  0 disk

卸载对应的硬盘

bash 复制代码

[root@ip-172-31-26-146 ~]# lsblk
NAME          MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
nvme0n1       259:0    0  40G  0 disk
