有時服務器需要添加新的硬盤,添加之后要經過分區、格式化、掛載才能使用,還要做開機自動掛載!
1.分區一般使用fdisk命令,參數-l:
#fdisk -l
Disk /dev/sda: 600.1 GB, 600127266816 bytes
255 heads, 63 sectors/track, 72961 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000862c9
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 26 3851 30720000 83 Linux
/dev/sda3 3851 4373 4194304 82 Linux swap / Solaris
Disk /dev/sdd: 600.1 GB, 600127266816 bytes
255 heads, 63 sectors/track, 72961 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
Disk /dev/sdb: 600.1 GB, 600127266816 bytes
255 heads, 63 sectors/track, 72961 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000862c9
Device Boot Start End Blocks Id System
/dev/sdb1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sdb2 26 3851 30720000 83 Linux
/dev/sdb3 3851 4373 4194304 82 Linux swap / Solaris
你可以看到有幾塊盤,大小,分區情況!
找到你新加的硬盤,進行分區,命令還是fdisk:
以/dev/sdc為例;
#fdisk /dev/sdc
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').
Command (m for help):
按下m,看下有哪些參數
按下p,打印已經分區好的信息
按下n,新建分區,然后選擇開始分區的地方、結束分區的地方;再次按下p,看下分區信息,按下w,保存;按下q,退出!!!
記住:分好區可以按下w保存,如果分區錯了,不要按下w,直接按下q,離開並且不會保存你剛剛進行的分區操作!
2.格式化分區
# mkfs.ext4 /dev/sdc1
等着就行,一般不會報錯
3.掛載
先創建掛載點/目錄
mkdir /xmon/
直接掛載
mount /dev/sdc1 /xmon
4.開機自動掛載 實現方式很多
(1)#vim /etc/fstab
增加一行 /dev/sdc1 /xmon ext4 defaults 0 0
(2)寫入/etc/rc/loacl文件
/dev/sdc1 /xmon ext4 defaults 0 0
等等,也可以寫入其他開機會讀取的配置文件或者是系統的環境變量!
