Proxmox Server: 1TB Root Partition on PVE-Root Filled on 100GB Backup Drive

Proxmox Server: 1TB Root Partition Filled 100GB - Backup Drive

Proxmox is an open-source server virtualization management solution, based on QEMU/KVM and LXC, that allows you to manage virtual machines (VMs) and containers. In this article, we will discuss a common issue with Proxmox servers that have a 1TB main drive and store VMs on a 1TB backup drive, where the 100GB partition for pve-root suddenly becomes filled completely.

Background

Proxmox servers are typically configured with a small root partition (usually around 100GB) for the operating system and application data, and a much larger partition or drive for storing VMs and other data. In the scenario we are discussing, the main drive is 2TB, with a 100GB partition for pve-root and the remaining space used for storing VMs. A 1TB backup drive is also attached to the server, which is used to store backups of the VMs.

The Issue

Recently, the 100GB partition for pve-root has become completely filled, despite there being plenty of space available on the backup drive. This can cause issues with the proper functioning of the Proxmox server, as there is no longer enough space for the operating system and application data to function properly.

Possible Causes

There are several possible causes for this issue. Some of the most common causes include:

• Log files: Proxmox servers generate a large number of log files, which can quickly consume a significant amount of space if they are not regularly monitored and cleaned up.
• Temporary files: Temporary files created by the operating system or applications can also consume a significant amount of space if they are not regularly cleaned up.
• Package cache: The package cache for the operating system can also consume a significant amount of space, especially if there have been a large number of package updates or installations.

Solutions

To resolve this issue, there are several steps that can be taken. Some of the most effective solutions include:

• Clean up log files: Regularly cleaning up log files can help to prevent them from consuming too much space. This can be done manually, or by using a tool such as logrotate.
• Clean up temporary files: Regularly cleaning up temporary files can also help to prevent them from consuming too much space. This can be done manually, or by using a tool such as tmpreaper.
• Clear the package cache: Clearing the package cache can help to free up a significant amount of space. This can be done manually, or by using a tool such as apt-get clean or yum clean all.
• Expand the root partition: If the root partition is consistently running out of space, it may be necessary to expand it. This can be done by resizing the partition or adding a new partition to the drive.

Proxmox servers with a 1TB main drive and a 1TB backup drive can experience issues with the 100GB partition for pve-root becoming filled completely. This can cause issues with the proper functioning of the Proxmox server. To resolve this issue, it is important to regularly clean up log files, temporary files, and the package cache. Additionally, expanding the root partition may be necessary if it is consistently running out of space.
