Homey Self-Hosted Server (SHS) in VMware Workstation DISK FULL

Homey Self-Hosted Server
1

Hi all,

I’m running Homey Self-Hosted Server (SHS) in VMware Workstation and I’m running into a disk space issue.

Homey is currently running:

  • Homey SHS: 13.5.0
  • VMware Workstation
  • Virtual disk: 64 GB
  • Linux root partition: only 7.5 GB
  • Filesystem: ext4
  • /root/.homey-shs: only about 165 MB
  • Docker itself reports only one active container.

The problem is that almost all disk usage is coming from containerd:

/var/lib/containerd                         ~5.0 GB
/var/lib/containerd/.../overlayfs           ~4.7 GB

df -h shows the root filesystem around 95–97% full.

I already tried the normal Docker cleanup commands:

docker container prune -f
docker image prune -a -f
docker system prune -a -f
apt-get clean
journalctl --vacuum-time=7d

Docker currently reports:

Images:       1
Active:       1
Size:         1.322 GB
Reclaimable:  0 B

Containers:   1
Active:       1
Size:         45 KB
Reclaimable:  0 B

However:

du -sh /var/lib/containerd/io.containerd.snapshotter.v1.overlayfs

still reports:

4.7G

I also noticed that containerd has a large number of snapshots/container objects:

ctr -n moby containers ls | wc -l
115

but:

ctr -n moby tasks ls

shows only one running task.

The snapshot usage shows several large layers, approximately:

~699 MiB
~698 MiB
~697 MiB
~695 MiB
~685 MiB

plus several layers around 249–250 MiB.

The current Homey container is:

ghcr.io/athombv/homey-shs:latest

and Docker only sees this one container:

homey-shs

My VMware VMDK is already 64 GB, but the Linux partition is only 7.5 GB:

/dev/sda     64G
├─/dev/sda1   7.5G  ext4  /
├─/dev/sda2   1K
└─/dev/sda5   480M  swap

So I have plenty of unused space on the virtual disk, but the root partition hasn’t been expanded.

My questions

  1. Is there a recommended/supported way in SHS to clean old containerd/overlayfs snapshots?
  2. Why does containerd have ~4.7 GB of overlayfs data while Docker reports only one active image/container?
  3. Are these old Homey image layers safe to remove using ctr, or should SHS/containerd handle the cleanup automatically?
  4. Is there a recommended procedure to expand /dev/sda1 from 7.5 GB to use the existing 64 GB virtual disk?
  5. Is there anything specific to Homey SHS I should do before modifying the partition layout?

I don’t want to manually delete anything from:

/var/lib/containerd/io.containerd.snapshotter.v1.overlayfs/

because I don’t want to break the Homey installation.

Any advice from someone familiar with the SHS/containerd setup would be greatly appreciated.

Thanks!
