<p dir="ltr">Reboot the VM to check if resize completed successfully.<br>
Check actual fs+partition+lvm sizes inside VM and verify their total size.</p>
<p dir="ltr">Shutdown VM and try to resize raw disk so that the total size is bigger at least some MB than the actual size.</p>
<p dir="ltr">For example if actual size is 1Tb resize it to 1.2-1.3 Tb just to be safe.</p>
<p dir="ltr">Try booting the VM again.<br>
