Due to insufficient free disk space on the VM, the /var/log resize operation could not be applied on reboot.
You will not know if resizing will succeed/fail ahead of time.
When available disk space on the VM is insufficient for the requested directory resizing.
Manually calculate and allocate disk space within the range of available disk space.
Improved validation has been added for directory resize operations. If the available disk space is less than the requested size, the command now fails immediately with a clear error message, allowing users to identify resize issues at the time of requesting.
