How to add an additional disk to SolusVM KVM VPS from a volume group that is not set in SolusVM?

Answer

1. Access the necessary SolusVM KVM node.

2. Manually create a logical volume:

   # lvcreate -n add_disk -L 50G second_vol_group

   Command parameters

   add_disk - name of the additional disk.

   vol_group - the name of the volume group - can be found with command vgs:

   # vgs
   VG #PV #LV #SN Attr VSize VFree
   centos 2 3 0 wz--n- 648.99g 1020.00m
   solusvm 2 7 0 wz--n- <119.94g <3.94g
   second_vol_group 1 1 0 wz--n- <299.97g <39.97g

   50G - size of the additional disk - 50G is an example - change it to the necessary value.

   <target dev='hda' bus='virtio'/>
   </disk>
   <disk type='file' device='disk'>
   <source file='/dev/second_vol_group/add_disk'/>
