ハードディスクを増設する2014/07/13 |
|
ハードディスクを増設した場合のパーティション作成です。
以下は、1台の SATA HDD が搭載されたマシンに、新たにもう1台 SATA HDD を増設し、増設した HDD 内に LVMパーティションを作成する場合を例示します。
HDD の物理的な増設手順については割愛し、パーティション作成のみを例とします。

The partition table has been altered! Calling ioctl() to re-read partition table. WARNING: Re-reading the partition table failed with error 16: Device or resource busy. The kernel still uses the old table.
