Background add a 150G disk to the Linux virtual machine and add the space to the/OPT directory. Add disk procedure skip the talk.
1. Execute "fdsik-l" to verify that the add is successful. Use FDISK to partition the newly added hard drive. Such as:
2. After creating the partition, execute the command partprone sync
[Email protected] ~]# Partprobe
3. Execute the command PVCREATE/DEV/SDB1 create the physical volume on the partition/DEV/SDB1.
[Email protected] ~]# PVCREATE/DEV/SDB1
Physical volume "/DEV/SDB1" successfully created
- Execute the command PVs to view the current physical volume, and of course it can be viewed with the Pvdisplay command.
[Email protected] ~]# PVs

- Execute command LVS View the volume group name of the home/home directory where the logical volume belongs
[[email protected] ~]# LVS

lv05 Vg00-wi-ao 4.00G
lv07 Vg00-wi-ao 72.06G------------can see that all the partitions are under the VG00 volume group
- Execute command vgextend vg00/dev/sdb1 to add the newly created physical volume/DEV/SDB1 to the volume group
[[email protected] ~]# vgextend vg00/dev/sdb1
Volume Group "vg00" successfully extended
- Execute command lvextend increase the logical volume/OPT by 100G
[Email protected] ~]# lvextend-l +100g/dev/mapper/vg00-lv07
Extending logical Volume LV07 to 172.06 GB
Logical Volume lv07 successfully resized
8. Execute Command resize2fs Sync
[Email protected] ~]# resize2fs/dev/mapper/vg00-lv07
