Linux detection and mounting the second hard disk step

When mounting the second hard disk under Linux, you need to check whether the hard disk can be recognized, and then mount the hard disk. The following small series will introduce you to the next. Linux mounts the second hard disk method, interested friends may wish to understand.

a, test drive can be identified

# fdisk -l

Disk /dev /sda: 36.7 GB, 36703934464 bytes

255 heads, 63 sectors/track, 4462 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/sda1 * 1 261 2096451 83 Linux

/dev/sda2 262 783 4192965 83 Linux

/dev/sda3 784 1305 4192965 83 Linux

/dev/sda4 1306 4462 25358602+ 5 Extended

/dev/sda5 1306 1827 4192933+ 83 Linux

/dev/sda6 1828 2088 2096451 82 Linux swap

/dev/sda7 2089 4462 19069123+ 83 Linux< Br>

Disk /dev/sdb: 36.7 GB, 36748945408 bytes

255 heads, 63 sectors/track, 4467 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sdb6 2812 3830 8185086 83 Linux

/dev/sdb7 3831 4467 5116671 83 Linux

/dev/sdb Description has identified the second Block hard disk

Second, mount the hard disk

1. Temporarily create a directory on the local hard disk

#mkdir /opt/data/tmp1

2 Mount one partition /dev/sdb1 in the second hard disk to tmp1

#mount /dev/sdb1 /opt/data/tmp1

3. Check whether it is mounted. >

# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda1 2.0G 141M 1.8G 8% /

none 1014M 0 1014M 0% /dev/shm

/dev/sda2 4.0G 1.8G 2.0G 47% /opt

/dev/sda7 18G 168M 17G 1% /opt/data

/dev/sda5 4.0G 1.4G 2.4G 37% /usr

/dev/sda3 4.0G 2.1G 1.8G 55% /var

/dev/sdb1 3.9 G 1.4G 2.3G 38% /opt/tmp/tmp1

Third, unmount the hard disk

#umount /dev/sdb1

The above is the second hard disk mounted by Linux. The method is introduced. In addition to the identification and mounting of the second hard disk, this article also explains the uninstallation of the hard disk.
