This article mainly introduces linux how to add hard disk partition mount, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let Xiaobian take you to understand.

Basic steps: partition-format-mount-write file

1. First use the fdisk-l command to check the name of the added hard disk, and you can see that sdb is the newly added hard disk.

[root@oracle] # fdisk-lDisk / dev/sdb: 21.5GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x00000000Disk / dev/sda: 21.5GB, 21474836480 bytes255 heads, 63 sectors/track 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x0006b59cDevice Boot Start End Blocks Id System/dev/sda1 * 1 39 307200 83 LinuxPartition 1 does not end on cylinder boundary./dev/sda2 39 2358 83 Linux/dev/sda3 2358 2611 2031616 82 Linux swap / Solaris

2. Partition, enter m to view the prompt

[root@oracle] # fdisk / dev/sdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabelBuilding a new DOS disklabel with disk identifier 0x09f38795.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): mCommand action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition 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)

Analysis: analysis of main parameters

1. Enter m to display all command lists.

two。 Enter p to display the hard disk partition and print the partition table.

3. Enter a to set the hard drive boot area.

4. Enter n to create a new hard disk partition.

4.1. Enter the e hard disk as a [extended] partition (extend).

4.2. Enter p hard disk as the [main] partition (primary).

5. Enter t to change the partition properties of the hard disk.

T: partition system id number

L:82:linux swap

83:linux

86:NTFS window partition

6. Enter d to delete the hard disk partition properties.

7. Enter Q to finish not saving the hard disk partition attribute.

8. Enter w to end and write the hard disk partition attribute

3. Enter n to create a new hard disk partition-- enter p to create a primary partition-- enter 1 to set a partition-- enter-enter-enter (default full space)

Command (m for help): nCommand action e extended extended Partition p primary partition (1-4) Primary Partition pPartition number (1-4): 1First cylinder (1-2610, default 1): Using default value 1Last cylinder, + cylinders or + size {K Magi M Magi G} (1-2610, default 2610): Using default value 2610

4. Enter p to view the partition-enter w to save and exit (be sure to save it or it will not work)

Command (m for help): P Disk / dev/sdb: 21.5GB, 21474836480 bytes255 heads, 63 sectors/track, 2610 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesSector size (logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512 bytesDisk identifier: 0x09f38795 Device Boot Start End Blocks Id System/dev/sdb1 12610 20964793 + 83 Linux Command (m for help): wThe partition table has been altered! Calling ioctl () to re-read partition table.Syncing disks.

5. The mkfs command formats the disk

[root@oracle ~] # mkfs.ext4 / dev/sdbmkfs.ext4: invalid fragment size-/ dev/sdb

6. Mount command mounts the partition

[root@oracle ~] # mount / dev/sdb / oracle/You have new mail in / var/spool/mail/root [root@oracle ~] # df-THFilesystem Type Size Used Avail Use% Mounted on/dev/sda2 ext4 19G 11G 7.3G% / tmpfs tmpfs 2.1G 74k 2.1G 1% / dev/shm/dev/sda1 ext4 297M 29M 253M 11% / boot/dev/sdb ext4 22G 47M 20G 1% / oracle

7. Add to / etc/fstab file, save and exit, otherwise the hard disk disappears after reboot.
