RSTe モード (IMSM) で RAID をビルドした後に partprobe を実行するとエラーが発生する

Issue

• 2 つのディスクを使用して RSTe モードで RAID1 をビルドし、partprobe を実行すると、次のエラーが表示されます。

Error: The backup GPT table is not at the end of the disk, as it should be.  This might mean that another operating system believes the disk is smaller.  Fix, by moving the backup to the end (and removing the old backup)?
Warning: Not all of the space available to /dev/sda appears to be used, you can fix the GPT to use all of the space (an extra 26288 blocks) or continue with the current setting?

• fdisk -l を実行すると以下の警告が表示されます。

GPT PMBR size mismatch (1781612543 != 1875385007) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
