Hi I have a PowerEdge server with a Perc controller and 4 x 1Tb disks in a RAID5, Plus a hot spare. Proxmox 5.3-1 all up set and running. However I now need to add an additional 1Tb disk to the RAID. From the Perc side of things that's all done. The Raid5 volume now has the 5 disks and the capacity of the raid volume is correct. What do I need to do inside proxmox either at GUI or SSH level so proxmox can see the additional space? When I do a pvdisplay on the server, I can see the following : 1. pv name /dev/sda3 (This is the one and only Raid array, as expected) When I do a lvdisplay on the server, I can see the following : 1. lv name swap, lv path /dev/pve/swap 2. lv name root, lv path /dev/pve/root 3. lv name data 4. ln name pve, lv path vm-100-disk-0 5. ln name pve, lv path vm-100-disk-1 6. ln name pve, lv path vm-101-disk-0 7. ln name pve, lv path vm-101-disk-1 All in the vggroup called pve. The LV size is still showing the original size and not the new size, so I obviously need to do something, but what? Many thanks in advance.
