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.
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
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
- Create a file system on the partition:
mkfs -t ext3 /dev/sdb1
- Make a directory where you will mount the new file system:
mkdir /newdata
- 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
- Mount it using the following command:
mount /newdata
Verify the results:
df -h
