Struggling with /home LVM contains all the free disk space with no free PE? Our talented Support Team has come up with a solution to ensure you have LVM storage.

We understand how frustrating it can be when your SolusVM stops creating LVM storage even though your /home partition has all the available disk space. Our Support Team has come up with a quick fix for this issue.

Why does your /home LVM contain all the free disk space with no free PE?

Are you struggling with no free PE space while the /home partition contains all the disk space of the server?

This situation can cause the SolusVM to stop creating LVM storage for KVM VPS as seen below:

# df -Th
Filesystem Type Size Used Avail Use% Mounted on
/dev/mapper/centos-root xfs 50G 7.1G 43G 15% /
devtmpfs devtmpfs 7.8G 0 7.8G 0% /dev
/dev/sda1 xfs 494M 185M 310M 38% /boot
/dev/mapper/centos-home xfs 169G 2.7G 166G 2% /home

Our Support Techs have narrowed down the cause behind this specific issue to incorrectly configured partition for the slave server during deployment.

One way to increase free PE would be to follow the partition procedure and ensure it is done correctly. However, our Support Engineers came up with an alternate solution for a client recently to resolve this issue.

How to resolve /home LVM partition taking up all the free disk space?

1. First, connect the slave server through SSH.
2. Then, take a copy of the required data from the /home partition to another secure location.
3. After that, unmount the /home file system as seen below:

   # unmount /home

4. Next, we will remove /home directory’s logical volume to make free space on Volume Group.

   # lvremove /dev/mapper/centos-home

5. Then, we will comment out or remove the /home entry in the /etc/fstab file. This will prevent auto-mount during the next reboot.

   # vim /etc/fstab
   #/dev/mapper/centos-home /home xfs defaulys 0 0

This handy tip will help you increase free PE in LVM.
