CentOS Add HDD

1. View New Hard Drive #fdisk –l The newly added hard drive is numbered/dev/sdb 2. Hard disk partition 1) Enter Fdisk mode #/sbin/fdisk/dev/sdb 2) enter N to partition 3) Select the partition type Here are two options: ? P: Primary partition can have a maximum of 4 main partitions on Linux ? E: There can be only 1 extended partitions on the extended partition Linux, the extended partition cannot be used directly after creation, and the logical partition on the extended partition will be created. Here I choose the P. 4) Select the number of partitions can choose 4 partitions, here I only divided into 1 partitions 5) Set the cylinder, select the default value here to 6) If you select E (extended partition), you need to create a logical partition Select n You can see that this is the option that appears and just a little different, appearing logical instead of extent. You can see that the partition number of logical starts at 5. Select L here to create the logical partition 7) Enter W, write to partition table, partition After the partition is finished, view the/dev directory #ls –l/dev If you are creating an extended partition, you can see the logical partition you created SDB5 You can see the new partition that you just generated SDB1 3. Format the partition Format the new partition as a ext3 file system 1) If you are creating a primary partition #mkfs-T EXT3/DEV/SDB1 2) If you are creating an extended partition, Because the extended partition cannot be used directly, execute #/sbin/mkfs-t EXT3/DEV/SDB1 command, the system will report the following error Invalid argument passed to Ext2 library while setting up Superblock In this case, only logical partitions on the extended partition can be formatted #/sbin/mkfs-t EXT3/DEV/SDB1 And then you start formatting Finally, the file system information is written. You can now use the newly created partition. 4. Mount the hard drive 1) Create mount point Create the storage directory under the root directory #mkdir/storage 2) mount the/DEV/SDB5 to the/storage #mount/dev/sdb5/storage 5, set the boot automatically mount The newly created partition cannot be mounted automatically and will be mounted manually each time the machine is restarted. Set boot auto mount requires modification of/etc/fstab file #vi/etc/fstab Add a line at the end of the file /dev/sdb5/storage ext3 Defaults 1 2 Tutorial finished!
