永久挂载磁盘

1. df -Th列出文件系统类型和文件系统的磁盘空间占用情况

[root@test ~]# df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/vda1      ext4       59G  3.1G   54G   6% /
devtmpfs       devtmpfs  3.9G     0  3.9G   0% /dev
tmpfs          tmpfs     3.9G     0  3.9G   0% /dev/shm
tmpfs          tmpfs     3.9G  344K  3.9G   1% /run
tmpfs          tmpfs     3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/vdb       ext4       59G   53M   56G   1% /data
tmpfs          tmpfs     783M     0  783M   0% /run/user/0

2. 通过fdisk -l 查看机器所挂硬盘个数及分区情况

[root@test ~]# fdisk -l 

Disk /dev/vda: 64.4 GB, 64424509440 bytes, 125829120 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: 0x000f3396

Disk /dev/vdb: 64.4 GB, 64424509440 bytes, 125829120 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 /dev/vdc: 107.4 GB, 107374182400 bytes, 209715200 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

[root@test ~]# mkfs.xfs -f /dev/vdc
meta-data=/dev/vdc               isize=256    agcount=4, agsize=6553600 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=0        finobt=0
data     =                       bsize=4096   blocks=26214400, imaxpct=25
         =                       sunit=0      swidth=0 blks

log      =internal log           bsize=4096   blocks=12800, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

3. 磁盘格式化

mkfs.xfs  -f /dev/vdc

4. 永久挂载

vim /etc/fstab

/dev/vdc  /store                                   xfs defaults 0 0

然后mount -a 没有报错说明挂载成功

最后df -Th 可以看到是否挂载

[root@test ~]# df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/vda1      ext4       59G  3.1G   54G   6% /
devtmpfs       devtmpfs  3.9G     0  3.9G   0% /dev
tmpfs          tmpfs     3.9G     0  3.9G   0% /dev/shm
tmpfs          tmpfs     3.9G  344K  3.9G   1% /run
tmpfs          tmpfs     3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/vdb       ext4       59G   53M   56G   1% /data
tmpfs          tmpfs     783M     0  783M   0% /run/user/0
/dev/vdc       xfs       100G   33M  100G   1% /store
