[Linux] Disk Operations

• 觀察磁碟分割狀態

lsblk

freeBSD:
camcontrol devlist

example:

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sr0 11:0 1 1.5G 0 rom /media/hubert/Ubuntu 16.04.3 LTS amd64
sda 8:0 0 40G 0 disk 
├─sda2 8:2 0 1K 0 part 
├─sda5 8:5 0 2G 0 part [SWAP]
└─sda1 8:1 0 38G 0 part /

• 磁碟分割與掛載

df mydir #查看zfs分割掛載
gpart show mydisk #查看gpt分割

• 分辨磁碟分割是GPT還是MBR

fdisk -l /dev/sda

example:

若出現:WARNING: GPT (GUID Partition Table) detected，則是GPT
若正常顯示磁碟分割，則是MBR

• 退出CD
