# Adding a Disk and Partitioning It
|
|
|
|
If the `df` command shows that the file system is indeed nearing capacity, you can add a new disk on the fly and partition it to increase capacity.
|
|
|
|
1. Add a new disk.
|
|
|
|
For example, you can add a new disk to a virtual machine by using the VMware vSphere Client. After adding a new disk, check for the new disk by using `fdisk`. In the following example, the new disk is named `/dev/sdb`:
|
|
|
|
fdisk -l
|
|
Device Start End Sectors Size Type
|
|
/dev/sda1 2048 16771071 16769024 8G Linux filesystem
|
|
/dev/sda2 16771072 16777182 6111 3M BIOS boot
|
|
|
|
Disk /dev/sdb: 1 GiB, 1073741824 bytes, 2097152 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
|
|
|
|
1. Partition it with the `parted` wizard.
|
|
|
|
The command to partition the disk on Photon OS is as follows:
|
|
|
|
parted /dev/sdb
|
|
|
|
Use the `parted` wizard to create it as follows:
|
|
|
|
mklabel gpt
|
|
mkpart ext3 1 1024
|
|
|
|
1. Create a file system on the partition:
|
|
|
|
mkfs -t ext3 /dev/sdb1
|
|
|
|
1. Make a directory where you will mount the new file system:
|
|
|
|
mkdir /newdata
|
|
|
|
1. Open `/etc/fstab` and add the new file system with the options that you require:
|
|
|
|
```
|
|
#system mnt-pt type options dump fsck
|
|
/dev/sda1 / ext4 defaults,barrier,noatime,noacl,data=ord$
|
|
/dev/cdrom /mnt/cdrom iso9660 ro,noauto 0 0
|
|
/dev/sdb1 /newdata ext3 defaults 0 0
|
|
```
|
|
|
|
1. Mount it using the following command:
|
|
|
|
`mount /newdata`
|
|
|
|
Verify the results:
|
|
|
|
```
|
|
df -h
|
|

|
|

|
|
