Mount 一個新的硬碟
46d8d217469b28f76fec6c621ec16a26.jpg
最近申請了中華電信的 hicloud ，新掛載 storage 時需要自己動手 fdisk & mount
 
很久沒手動做這個事情了!~ 記錄一下免得忘記!

步驟

  • 先確認硬體配置
    # fdisk -l

Disk /dev/sda: 107.4 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 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: 0x0009c50e

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       12010    96467968   83  Linux
/dev/sda2           12010       13055     8388608   82  Linux swap / Solaris

Disk /dev/sdb: 107.4 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 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
     
    /dev/sdb 是新掛進來的，也是需要 fdisk 處裡的
  • 開始新增 Partition
    # fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xd3b9abf3.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

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): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-13054, default 1):
Using default value 1
Last cylinder, +cylinders or +size{K,M,G} (1-13054, default 13054):
Using default value 13054
     
    用 p 看看是否有新增成功
    Command (m for help): p

Disk /dev/sdb: 107.4 GB, 107374182400 bytes
255 heads, 63 sectors/track, 13054 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: 0xd3b9abf3

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       13054   104856223+  83  Linux
     
    確定後就下 w 寫入 partition 資訊囉!
    Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.
  • 寫入後原則上需要重開機，但是如果不想重開就執行
    # partprobe
Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy).  As a result, it may not reflect all of your changes until after reboot.
     
    如果沒有這個指令就安裝一下
    yum install parted
  • 建立 file system
    mkfs -t ext4 /dev/sdb1
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
6553600 inodes, 26214055 blocks
1310702 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
800 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
        4096000, 7962624, 11239424, 20480000, 23887872

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 34 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
  • mount 到需要的位置 (ex: /mnt/datastore/)
    mount /dev/sdb1 datastore
     
    這樣就大功告成囉!
