Resizing of VM Disk does not work

[manuelkamp]

Hi,

I figured a strange bahaviour. Today I wanted to enlarge the disk of a ubuntu VM. I started with adding space via Proxmox GUI. Then I connected to the VM via putty and made the changes with parted. This worked:

root@srv-rpx:~# fdisk -l /dev/sda | grep ^/dev                        
/dev/sda1     2048     4095     2048    1M BIOS boot
/dev/sda2     4096  1576959  1572864  768M Linux filesystem
/dev/sda3  1576960 23068638 21491679 10,3G Linux filesystem

root@srv-rpx:~# lsblk

sr0                        11:0    1 1024M  0 rom

Then I wanted to enlarge the fs with:

root@srv-rpx:~# lvresize --extents +100%FREE --resizefs /dev/ubuntu-vg/ubuntu-lv
  Size of logical volume ubuntu-vg/ubuntu-lv unchanged from <10,25 GiB (2623 extents).
  Logical volume ubuntu-vg/ubuntu-lv successfully resized.
resize2fs 1.45.5 (07-Jan-2020)
The filesystem is already 2685952 (4k) blocks long.  Nothing to do!

But you can already see, it does not apply anything. I am stuck here - any suggestions please?

nvm, vm reboot solved it.

Occassionally, I notice this happens and it persists VM reboots... Any other solutions? One that has worked for me is shutdown, resize again, boot up.
Thanks,

Just an update in this instance, dmesg is not listing any capacity changes... Hmm Doesn't matter whether it's over CLI or PVE GUI.

Detaching, rebooting, and attaching also have not solved it.
