I'm experiencing a strange issue, after I extended the HP RAID array
This server acts as a hypervisor (CentOS - KVM) and I'm using logical volumes for the KVM guests. When I check the physical volumes (pvs) on the hypervisor - for some reason it shows the physical volumes from the KVM guests as well (the same applies to volume groups and logical volumes)
# pvs
PV VG Fmt Attr PSize PFree
/dev/disk/by-id/dm-name-vg_01-vm01 vg_vm01 lvm2 a-- 49.51g 4.88g
/dev/disk/by-id/dm-name-vg_01-vm02 vg_vm02 lvm2 a-- 159.51g 4.88g
/dev/disk/by-id/dm-name-vg_01-vm03 vg_vm03 lvm2 a-- 159.51g 4.88g

/dev/disk/by-id/dm-name-vg_01-vm08 vg_vm08 lvm2 a-- 159.51g 4.88g
/dev/sda2 vg_main lvm2 a-- 24.00g 0
/dev/sda3 vg_kvm lvm2 a-- 1.61t 702.17g
I'm not sure if this is related but after I extended the HP RAID array I run partprobe
on the system.
Please advise how to fix this and why this issue occurs.
