 +==== Re-read Partition Table ====
 +
 +Sometimes, after you create a new partition and write changes, you could see this message:
 +<code bash>
 +OK; writing new GUID partition table (GPT) to /dev/xvdf.
 +Warning: The kernel is still using the old partition table.
 +The new table will be used at the next reboot.
 +The operation has completed successfully.
 +</code>
 +
 +\\
 +Instead of rebooting, inform the kernel that changes have been made on the disk:
 +<code bash>
 +partprobe /dev/xvdf
