/home LVM contains all the free disk space on SolusVM KVM node

Symptoms

During installation of the slave node there are no free PE left on the server and /home partition has all the disk space of the server. As a result, SolusVM cannot create any LVM storage for KVM VPS

Cause

Partition configured incorrectly for the slave server during its deployment

Resolution

Check our community post with an example of partitioning procedure on SolusVM KVM node.

Otherwise, the following steps can be used as a workaround.

Warning: It is not recommended to perform the steps below if are not familiar with Linux Partitioning. Incorrect settings can make the server completely broken.

1. Connect to the slave server via SSH
2. Copy required data from /home partition to different location
3. Unmount /home file system
   

   # umount /home

4. Remove the logical volume of /home directory to make free space on Volume Group
   

   # lvremove /dev/mapper/centos-home

5. Remove or comment out /home entry in /etc/fstab file to avoid the auto-mount on next reboot:
   

   Open file with preferable text editor, for example vim

   # vim /etc/fstab

   Put # sign at the begining of the line for commenting

   CONFIG_TEXT: #/dev/mapper/centos-home /home xfs defaulys 0 0
