After installing a new hard disk, enter it in the terminal to view the hard disk partition:
# ls -al /dev/sd* # fdisk -l
Of course, you can also enter the web management page Node-> Disk.
You can see the name of your newly connected device
sdb is the new partition, but it has not been formatted
Use the fdisk command to assign a partition to the new hard disk
# fdisk /dev/sdb
Hard disk formatted as ext4
# mkfs.ext4 -t ext4 -m0 /dev/sdb
Hang on a new hard drive
# mkdir /data
Add a new folder, the name can be customized.
It is used to store virtual machines. The hard disk on which I install Proxmox VE (Proxmox Virtual Environment) is an SSD with a relatively small capacity, which is not enough for me to store virtual machines. The new hard disk is used to store virtual machines.
Mount sdb1 to /data
# mount /dev/sdb /data
# df -h
# ls -alF /dev/disk/by-uuid/
Write down the long list of UUID of sdb1, here I am 856e9b8f-b0f1-49f2-a19a-71989a7a8e92
Write UUID to /etc/fstab, and the new hard disk will be automatically loaded and mounted under the /data directory every time you turn it on.
# vi /etc/fstab
Add two lines
UUID=854e8ah8f-b0f1-49f2-e44a-71982e8a6e92 /data ext4 defaults 0 0 /data/images /var/lib/vz/images none bind 0 0 /dev/sdb /data ext4 defaults 0 0 /dev/sdb1 /var/lib/vz/images ext4 defaults 0 0
See if the mount is successful
# mount -a
Let the system reload all the contents of /etc/fstab so that there is no need to restart.
# mount -l
Add new storage
