1. Basic terminology of LVM

Physical volumes (physical volume): physical disk partitions

$pvdisplay # display physical volumes $pvcreate / dev/sdb1 # create physical volumes

Volume group (volume group): a disk partition in LVM, which can be understood as a disk repository

$vgdisplay # display volume group $vgextend cl / dev/sdb1 # extended volume group

Logical volumes (logical volume): logical partitions from VG

$lvdisplay # shows the logical volume $lvextend-L + 100G / dev/cl/root # extended capacity 2. Add new hard disk expansion LVM partition 2.1 add partition $fdisk / dev/sdbn # create partition p # Select primary partition 1 # partition number, / dev/sdb1t 8e # partition type linux LVMw # write partition table $partprobe # reread partition table $mks.xfs / dev/sdb1 # format $partx / dev/sdb # View partition 2.2 create PV, expand VG LV$ pvcreate / dev/sdb1 # create PV$ vgdisplay$ vgextend cl/ dev/sdb1 # extend VG$ lvdisplay$ lvextend-L + 100G / dev/cl/root # extend LV$ resize2fs / dev/cl/root # perform resize, fix non-xfs2.3 xfs file system problem

In xfs file systems, you can only increase the partition, not decrease it. After the xfs file system is logically extended, it takes one step to complete:
