I have a ubuntu 14 Vm of 32GB that was cloned.
Wanted to increase the cloned VM to 100 GB.
Now as per the documentation Proxmox Resize Disk

After starting the VM I ran the command.
root@atp:~# qm resize 101 virtio0 +68G
WARNING: You have not turned on protection against thin pools running out of space.
WARNING: Set activation/thin_pool_autoextend_threshold below 100 to trigger automatic extension of thin pools before they get full.
Size of logical volume pve/vm-101-disk-0 changed from 32.00 GiB (8192 extents) to 100.00 GiB (25600 extents).
Logical volume pve/vm-101-disk-0 successfully resized.
WARNING: Sum of all thin volume sizes (832.00 GiB) exceeds the size of thin pool pve/data and the amount of free space in volume group (15.99 GiB).
root@atp:~#

Seems the increase was successful as it was detected inside the guest ubuntu VM
atp@atp:~$ dmesg | grep vda
[ 0.518286] vda: vda1 vda2 < vda5 >
[ 0.861727] EXT4-fs (vda1): mounted filesystem with ordered data mode. Opts: (null)

[ 79.714018] vda: detected capacity change from 34359738368 to 107374182400

Issue is that according the to documentation the "fdisk -l /dev/vda | grep ^/dev" should show a mismatch, but it does not!
Althought it does show that /dev/vda is 107.4GB now.
atp@atp:~$ sudo fdisk -l /dev/vda

/dev/vda5 58920960 67106815 4092928 82 Linux swap / Solaris

How do i proceed from this point onward?
Anything that I have missed?
 
Hi,
now you can create a new partition with the newly available space and a filesystem on top of it (that is if you don't want to use it for something other than a filesystem). And after you've done that, create a mount entry in /etc/fstab to mount it automatically at boot.
