In this article, I will take you through the steps to delete Volume Group in Linux. Volume group is a logical aggregation of physical volumes in LVM(Logical Volume Manager) Technology. This acts as a storage reservoir in LVM where the storage can be added by adding multiple physical volumes ...
卷组(VG Volume Group) LVM卷组类似于非LVM系统中的物理硬盘,其由物理卷组成。可以在卷组上创建一个或多个“LVM分区”(逻辑卷),LVM卷组由一个或多个物理卷组成。 逻辑卷(LV logical volume) LVM的逻辑卷类似于非LVM系统中的硬盘分区,在逻辑卷之上可以建立文件系统(比如/home或者/usr等)。 PE(physical exten...
Delete physical volumes used for volume group**“vg01”**: [root@O-Friday ~]# pvremove /dev/sdb /dev/sdcLabels on physical volume"/dev/sdb"successfully wiped. Labels on physical volume"/dev/sdc"successfully wiped. [root@O-Friday ~]# pvdisplay--- Physical volume --- PV Name /dev/sda...
Physical volume "/dev/sdd1" successfully created 2,建VG # vgcreate md3200 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 Volume group "md3200" successfully created # lvcreate -n md3200lv1 -L 8T md3200 Logical volume "md3200lv1" created You have new mail in /var/spool/mail/root 3,建...
2.物理卷(Physical Volume,PV) 物理卷和磁盘/硬盘有何关联,列出系统已有PV及相关属性,添加/删除/维护PV属性 3.卷组(Volume Group,VG) VG的创建,删除,扩容,维护和导入导出迁移,查看相关属性 4.物理分区(Physical Parttion,PP) 什么是PP 5.逻辑分区(Logical Partition,LP) 什么是LP 6.逻辑卷(Logical Volume,...
# pvcreate /dev/sdd Physical volume "/dev/sdd" successfully created 使用以下命令将新的物理卷 /dev/sdd 添加到现有卷组 vg01 中。 # vgextend vg01 /dev/sdd Volume group "vg01" successfully extended 现在,使用 pvs 命令查看你添加的新磁盘 /dev/sdd。
将/dev/sda3添加导/dev/sda2对应的VG中去 [root@hadoop03 ~]# vgextend cl /dev/sda3 Volume group "cl" successfully extended # 5.再次查看物理卷信息(对比上面看看) [root@hadoop03 ~]# pvdisplay --- Physical volume --- PV Name /dev/sda2 VG Name cl PV Size <29.00 GiB / not ...
4. Delete lvm volume : # lvremove /dev/datavg/testlv 5. Disable volume group : # vgchange -an datavg 6. Delete volume group : # vgremove datavg 7. Delete physical Volumes being used for the volume group “datavg” : # pvremove /dev/sdb /dev/sdc...
The post describes steps to delete a volume group. Make sure you have unmounted and the mount points and taken prior backup of the mount point if required. 1. Once you have umounted all the mount points, you can remove the LVs associated with them. To do so use the lvremove command :...
卷组(VG):(volume group),把多个物理卷组成一个逻辑的整体,这样卷组的大小就是多个硬盘之和。或者理解就是由一个或多个PV组成的整体。(面团) 逻辑卷(LV):(logical volume),从卷组中划分需要的空间大小出来。用户仅需对其格式化然后即可挂载使用。从VG中切割出的空间用于创建文件系统。(切成馒头) ...
