Symptoms
We've seen several servers provided by ovh.com where the server's disk size was larger but the root ("/") partition was allocated only about 8 GB of disk space.
# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 40G 0 disk
└─sda1 8:1 0 7.8G 0 part /
loop0 7:0 0 500M 0 loop /var/tmp
Description
This issue appears to be caused by a templating issue at OVH. You'll want to contact them directly to make sure that your servers have a root filesystem that meets at least the minimum requirements for cPanel:
How large should the root partition be?
Workaround
You might be able to grow or extend the sda1 partition to use the full disk by running the following commands as root:
yum -y install cloud-utils
growpart /dev/sda 1
resize2fs /dev/sda1
Note that the growpart command has a space between sda and "1". This is intentional, and will allow the partition to grow to the size of the disk.
If you encounter an error or are unsure how to proceed, you may benefit from contacting a system administrator for further investigation. If you do not have such an administrator, you may search for one in our listings here:
