Linux如何使用超過2TB以上的裝置(HDD,iSCSI)空間(將partition切成...
情境：大於2TB以上的硬碟，若要使用fdisk做分割partition的動作，可能會出現一些警語或是無法查看相關訊息，因此要使用parted指令來做切割partition(並使用GPT格式)。step 1) 安裝parted套件
# yum install -y parted
step 2) 切partition，並使用GPT
# parted /dev/sdb
----------------------------------------------------------
GNU Parted 1.8.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt
Warning: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want
to continue?
parted: invalid token: gpt
Yes/No? yes
New disk label type? ? gpt
(parted) mkpart
Partition name? []? primary
File system type? ? ext4
Start? 0
End? -1
(parted) print
Model: OPNFILER VIRTUAL-DISK (scsi)

step 3) 查看是否已使用GPT格式
# fdisk -l
