Once upon a time, simon(a)justconnect.ie <simon(a)justconnect.ie&gt; said: What is the OS running in the VM, and what type of disk is it (virtio, virtio-scsi, IDE)? Newer Linux versions should see a virtio/virtio-scsi disk size change immediately. Some older versions had ways to trigger a rescan to see the size change, while some required a reboot. -- Chris Adams <cma(a)cmadams.net&gt;

Thanks All, Rescans and reboot didn't resolve this - disk size increase still not seen by OS. Any other suggestions? Regards Simon...

Hi Strahil, Clicked edit on the VMs disk and then entered the required size to extend the disk in "Extend size by (GiB)" window. The UI showed the correct size of the disk but lsblk on the Guest failed to show any changes.

Hi Strahil, Apologies for the delay. # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 100G 0 disk `-sda1 8:1 0 100G 0 part |-vg00-root 253:4 0 99G 0 lvm / `-vg00-swap_1 253:5 0 980M 0 lvm [SWAP] sdb 8:16 0 100G 0 disk `-sdb1 8:17 0 100G 0 part |-vg_02-lv_nfs-real 253:0 0 95G 0 lvm | |-vg_02-lv_nfs 253:1 0 95G 0 lvm /nfs | `-vg_02-lv_nfs_snap 253:3 0 95G 0 lvm `-vg_02-lv_nfs_snap-cow 253:2 0 1G 0 lvm `-vg_02-lv_nfs_snap 253:3 0 95G 0 lvm sr0 11:0 1 1024M 0 rom We have tried all manner of rescans ( https://serverfault.com/questions/306737/how-do-i-get-centos-vm-to-re-rea... ) but nothing shows the additional space allocated.
