We all know that after xenserver is installed, no matter how large your disk is, There is only 4 GB space.

Therefore, the operation is to create an LV volume and customize the size.

1. vgdisplay # view the remaining space first

[Root @ XenServer/] # vgdisplay

3. lvcreate-L 20 GB-n iso VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2 # New 20 GB lv volume iso

[Root @ XenServer/] # lvcreate-L 20 GB-n iso VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2

Logical volume "lviso" created

This document introduces how to add a space:

[Root @ XenServer/] # lvcreate-n lviso-L + 6G VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2

Logical volume "lviso" created

4. lvdisplay VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2 # view the area again

[Root @ XenServer/] # lvdisplay VG_XenStorage-205eecff-2466-84fe-56d5-81472e44f3c2
