news 2026/5/12 2:49:52

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

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

2、卸载目录路径

[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

[root@ip-172-31-26-146 ~]# lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS nvme0n1259:0040G0disk ├─nvme0n1p1259:1040G0part / ├─nvme0n1p127259:201M0part └─nvme0n1p128259:3010M0part /boot/efi nvme1n1259:4015G0disk └─vg_data-lv_data253:0060G0lvm nvme2n1259:5015G0disk └─vg_data-lv_data253:0060G0lvm nvme3n1259:6015G0disk └─vg_data-lv_data253:0060G0lvm nvme4n1259:7015G0disk └─vg_data-lv_data253:0060G0lvm[root@ip-172-31-26-146 ~]# df -hFilesystem Size Used Avail Use% Mounted on devtmpfs4.0M04.0M0% /dev tmpfs3.9G4.0K3.9G1% /dev/shm tmpfs1.6G 640K1.6G1% /run /dev/nvme0n1p1 40G 11G 30G26% / tmpfs3.9G03.9G0% /tmp /dev/nvme0n1p128 10M1.3M8.7M13% /boot/efi tmpfs 782M0782M0% /run/user/1000 overlay 40G 11G 30G26% /var/lib/docker/overlay2/84699b7470c48b0c4a1cb8b91b868be21f96c388de173f25df9ac741be7d0d0e/merged

4、删除lvs

[root@ip-172-31-26-146 ~]# lvsLV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert lv_data vg_data -wi-a-----59.98g[root@ip-172-31-26-146 ~]# lvremove /dev/vg_data/lv_dataDo you really want to remove active logical volume vg_data/lv_data?[y/n]: y Logical volume"lv_data"successfully removed.

5、删除vg

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

6、删除pv

[root@ip-172-31-26-146 ~]# pvremove /dev/sdbLabels on physical volume"/dev/sdb"successfully wiped.[root@ip-172-31-26-146 ~]# pvremove /dev/sdcLabels on physical volume"/dev/sdc"successfully wiped.[root@ip-172-31-26-146 ~]# pvremove /dev/sddLabels on physical volume"/dev/sdd"successfully wiped.[root@ip-172-31-26-146 ~]# pvremove /dev/sdeLabels on physical volume"/dev/sde"successfully wiped.[root@ip-172-31-26-146 ~]# pvs

LVM 结构已经被彻底删除

查看删除lvs后对应的存储卷

[root@ip-172-31-26-146 ~]# lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS nvme0n1259:0040G0disk ├─nvme0n1p1259:1040G0part / ├─nvme0n1p127259:201M0part └─nvme0n1p128259:3010M0part /boot/efi nvme1n1259:4015G0disk nvme2n1259:5015G0disk nvme3n1259:6015G0disk nvme4n1259:7015G0disk

卸载对应的硬盘

[root@ip-172-31-26-146 ~]# lsblkNAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS nvme0n1259:0040G0disk ├─nvme0n1p1259:1040G0part / ├─nvme0n1p127259:201M0part └─nvme0n1p128259:3010M0part /boot/efi
