+
+Welcome to fdisk <removed>.
+Changes will remain in memory only, until you decide to write them.
+Be careful before using the write command.
+
+GPT PMBR size mismatch (20479 != 40959) will be corrected by write.
+The backup GPT table is not on the end of the device. This problem will be corrected by write.
+
+Command (m for help): Partition number (2-128, default 2): First sector (20447-40926, default 20480): Last sector, +sectors or +size{K,M,G,T,P} (20480-40926, default 40926): 
+Created a new <removed>.
+
+Command (m for help): The partition table has been altered.
+Calling ioctl() to re-read partition table.
+Re-reading the partition table failed.: Invalid argument
+
+The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8).
