继上一篇 【Linux上创建一个LVM卷组,将多个物理卷添加到卷组中使用】
创建一个卷组,并将多个物理卷添加到该卷组中。
在卷组上创建一个逻辑卷,并进行文件系统格式化。
将逻辑卷挂载到指定目录并自动挂载。
扩展逻辑卷的大小,并调整文件系统以适应扩容后的存储空间。
那么这篇是Linux 对磁盘进行清理、重建、配置文件系统和挂载
的一系列操作,进行系统存储管理 调整存储结构
使用命令 lsblk 如下:
[root@hnode3 ~]# lsblk

[root@hnode3 ~]# mkfs.ext4 /dev/sdd1
mke2fs 1.39 (29-May-2006)
/dev/sdd1 isapparently in use by the system; will not make a filesystem here!
WC报错:
意思是:/dev/sdd1 似乎已经被系统占用,无法在这里创建文件系统
。sdd1 是一个硬盘设备文件,如
果在使用中,系统可能已经分配了这个设备。可以看到第一步执行结果挂载点MOUNTPOINT下有/data
。为了创建文件系统,需要先卸载占用
这个设备的程序,或者将设备重新分配给系统
。那怎么办呢?咱们往下走。
卸载现有的文件系统:
umount /dev/sdd1
创建一个新的ext4文件系统:
mkfs.ext4 /dev/sdd1
在创建新的文件系统时,如果您的设备上已经存在一个或多个文件系统,则必须先卸载它们,否则将无法创建新的文件系统。此时还会报错,继续!
使用 fdisk 或 parted 命令格式化 sdd1 设备,然后重新挂载 sdd1 设备 fdisk /dev/sdd1
查看卷组信息
vgs或者vgdisplay
VG #PV #LV #SN Attr VSize VFree
vg_data 24 1 0 wz-pn- <26.20t <17.41t
vg_srv 3 7 0 wz--n- 3.27t <985.62g
1.检查是否有文件系统或其他进程挂载或访问卷组(可跳过)
2.卸载文件系统
提示:删除逻辑卷之前先卸载文件系统是因为逻辑卷上的文件系统可能正在被使用,文件系统是在逻辑卷上创建的,他是负责管理文件和目录的结构以及存储数据的组织方式。文件系统被挂载后,系统会不断地读取、写入、修改文件和目录以及更新文件系统的元数据。如果这种情况下直接删除逻辑卷,则会中断文件系统的正常操作,可能会导致文件丢失、数据损坏或文件系统无法恢复。所以在删除逻辑卷之前必须使用umount命令卸载文件系统保证不再被系统或其他进程使用。
umount /dev/卷组名称/逻辑卷名称
umount /dev/vg_data/edp_data
此时,再执行第一步lsblk命令MOUNTPOINT下的 /data 就应该消失了接下来编辑/etc/fstab文件,注释掉逻辑卷对应的挂载目录,如下:
#/dev/vg_data/edp_data /data ext4 defaults 0 0
3-4. 删除指定逻辑卷
lvremove /dev/vg_data/edp_data
此时,再执行第一步lsblk命令 sdd1、sde1、sdf1、sdg1、sdh1、sdi1、sdj1、sdk1、sdjl 下的逻辑卷vg_data-edp_data 就应该消失了
3-5. 删除卷组
执行命令
vgremove vg_data
可能出错:Volume group “vg_data” not found, is inconsistent or has PVs missing.
出错原因:物理卷缺失或元数据描述不一致
解决方法:
vgreduce --removemissing vg_data
然后再执行 vgremove vg_data 即可。
过程如下:
[root@hnode2 ~]# vgs
