設定VMware掛載新加入的磁碟
2020-06-16 17:23:31
在VMware虛擬機器設定中增加磁碟後,啟動Linux,使用root登入。
首先檢視未分割區的磁碟,使用下面命令:
## 檢視未使用的磁碟
fdisk -l
磁碟/dev/sdb後面沒有任何分割區,是新掛載的磁碟
輸入下面命令來開始對磁碟/dev/sdb進行分割區
## 開始格式化磁碟 ##
fdisk /dev/sdb
有如下提示:
[root@localhost dev]# fdisk /dev/sdb Welcome to fdisk (util-linux 2.23.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Command (m for help):
輸入m來檢視幫助,各選項功能如下:
Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition g create a new empty GPT partition table G create an IRIX (SGI) partition table l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only)
首選使用n來建立一個擴充套件分割區,輸入選項n:
Command (m for help): n Partition type: p primary (0 primary, 0 extended, 4 free) e extended Select (default p):
選擇建立擴充套件分割區,輸入選項e,然後選擇擴充套件分割區編號、起始位置和大小,我們選擇整個磁碟只建立一個擴充套件分割區:
Select (default p): e Partition number (1-4, default 1): 1 First sector (2048-41943039, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-41943039, default 41943039): Using default value 41943039 Partition 1 of type Extended and of size 20 GiB is set
擴充套件分割區建立好後,可以在此基礎上進行建立邏輯分割區,我們建立2個邏輯分割區並分別設定為10G:
Command (m for help): n Partition type: p primary (0 primary, 1 extended, 3 free) l logical (numbered from 5) Select (default p): l Adding logical partition 5 First sector (4096-41943039, default 4096): Using default value 4096 Last sector, +sectors or +size{K,M,G} (4096-41943039, default 41943039): +10G Partition 5 of type Linux and of size 10 GiB is set Command (m for help): n Partition type: p primary (0 primary, 1 extended, 3 free) l logical (numbered from 5) Select (default p): l Adding logical partition 6 First sector (20977664-41943039, default 20977664): Using default value 20977664 Last sector, +sectors or +size{K,M,G} (20977664-41943039, default 41943039): Using default value 41943039 Partition 6 of type Linux and of size 10 GiB is set
最後使用選項p來檢視分好的分割區:
Command (m for help): p Disk /dev/sdb: 21.5 GB, 21474836480 bytes, 41943040 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x40e44e64 Device Boot Start End Blocks Id System /dev/sdb1 2048 41943039 20970496 5 Extended /dev/sdb5 4096 20975615 10485760 83 Linux /dev/sdb6 20977664 41943039 10482688 83 Linux
為磁碟分配好分割區後,需要使用選項w來進行儲存:
Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
在執行partprobe命令來重新讀取分割區資訊,如果有警告可以忽略。
## 重新讀取分割區資訊 ##
partprobe
然後需要對磁碟進行格式化,使用mkfs將磁碟格式化為ext4格式(注意擴充套件分割區不能進行格式化)
mkfs -t ext4 /dev/sdb5
mke2fs 1.42.9 (28-Dec-2013) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 655360 inodes, 2621440 blocks 131072 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=2151677952 80 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 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done
然後我們建立兩個目錄來掛載這兩個邏輯分割區:
## 然後建立目錄 ## mkdir /disk5 /disk6 ## 使用mount命令來掛載目錄 ## mount /dev/sdb5 /disk5 mount /dev/sdb6 /disk6
最後使用mount命令來檢視掛載情況
[root@localhost dev]# ## 使用mount命令來檢視掛載情況 ## [root@localhost dev]# mount | grep "sdb" /dev/sdb5 on /disk5 type ext4 (rw,relatime,seclabel,data=ordered) /dev/sdb6 on /disk6 type ext4 (rw,relatime,seclabel,data=ordered)
