-====== List Create Delete Partitions On Mbr And Gpt Disks ====== 
- 
-**General Information** 
- 
-  * Disks with a MBR (master boot record) are limited to 4 primary partitions and 2TB max usable size. 
-    * Use fdisk or parted. 
-  * Disks with GPT lift both of these restrictions. 
-    * Use gdisk or parted.

-==== 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 
-</code>
