Code : # Fdisk/dev/SDB
Enter the fdisk mode:
Command (M for help): P // view the partition of the New Hard Disk
Command (M for help): N // to create a new partition, run the M command to check the internal command of the fdisk command. Run the N command to create a new partition. Run the D command to delete an existing partition; the p command displays the partition list; the T command modifies the ID number of the partition type; the l command displays the list of partition ID numbers; and The a command specifies to start the partition; the W command is used to modify and save the Partition Table disk. Command action
E extended // input e to create an extended partition
P primary partition (1-4) // input P to create the primary partition. Here we select ppartion number (1-4): 1 // The first extended partition, you can divide up to four primary partitions as needed
First cylinder (1-1014, default 1): 1 // Number of disks starting from the first primary Partition
Last cylindet or + Siza or + sizem or + sizek: + 1024 MB // It Can Be A number in MB or the number of disk blocks, here, we enter + MB to indicate that the partition size is 1 GB.
In this way, we have created a partition. If you want to create more partitions, you can continue to create the partition according to the above steps. After the partition is created, use W to save the partition.
Code: Command (M for help): W
The partition table has been altered! Calling IOCTL () to re-read partition table.
Syncing disks.
In this way, the partition is complete and we need to format it.
Code: # mkfs-T ext3-C/dev/sdb1 // if multiple partitions exist, modify the partition to sdb2.
After formatting, we need to mount the partition,
Code: # mkdir www // create/WWW directory. We will mount the new partition to www
# Mount/dev/sdb1/www // Mount/dev/sdb1 to/WWW
# DF // use the DF command to view
Filesystem 1k-blocks used available use % mounted on
/Dev/sda2 3771316 1388956 2190788 39%/
/Dev/sda1 101089 9463 86407 10%/boot
None 62988 0 62988 0%/dev/SHM
/Dev/sdb1 485906 8239 452580 2%/www // you can see that this is the partition we just mounted.
At this point, our work is coming to an end. However, if we end this way, we need to manually mount the server every time we restart the server, which is very troublesome, we need to modify the/etc/fstab file for automatic mounting.
Code: # vi/etc/fstab
Add the following content at the end of the file:
Code:/dev/sdb1/WWW ext3 defaults 1 2
Modify sdb1 and/WWW if there are multiple partitions. Save the modification and restart the server. Now we have finished adding a new hard disk.
