##### Bug report summary Hi thanks for the lib! I find the “disk” section incomplete. It does not have `disk_spaces._`/`disk_usages._` chart for most of the disks (e.g. `sda`, `sdb`, … and `dm-1`, `dm-2`, … It only has that for a few disks like `/`. In addition, even for the `/` filesystem, the disk size that netdata says is _different_ from the actual value. When execute `df -h` in my host machine, it says `/dev/vda1 40G 3.5G 34G 10% /`. But as you can see from figure 1, netdata think it is 8GB (not 40GB). I guess it is related to permission problems and problems of container volume mapping? Possibly related (not sure): [Disk space not available · Issue #3716 · netdata/netdata · GitHub](https://github.com/netdata/netdata/issues/3716). But I do not have any ideas on how to solve this. Thanks! figure 1: it has metrics for `/` ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/1X/76f4eaffd47c29c84860f42c18b9fa78126c7c5c.png) figure 2: it does **not** for `sda` ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/1X/79399c0bfeab05399d93a12a3df0f11188dfbcff.png) ##### OS / Environment ```auto kubernetes on centos 7 ``` ##### Netdata version latest ##### Component Name disk ##### Steps To Reproduce 1. install official helmchart 2. see it ##### Expected behavior should see correct metrics * * * I have already tried to mount `/mnt` to `/host/mnt` (hoping that things like `/mnt/sda`, `/mnt/sdb`, etc can be found), but no success. Nothing more is appeared in the UI. ☹ Any suggestions? ---

@vlvkobal Sorry I am new to Linux, so ignore my “they are just normal disk partitions”. I did not clearly used those terms. Here are df reults: 1.

@vlvkobal Restate my goal: I need to monitor the **Persistent Volumes** of kubernetes. For example, pod A may require a persistent volume of 40GB. Then I want to get an alert when it is going to use up all the space, such that I can take action by increasing the disk size. Thanks very much! ---

Don’t you have `/host/mnt/paas/kubernetes/kubelet/pods/*` in the Netdata dashboard? Please make a new snapshot of your Disk section. ---

By the way I try to debug the diskspace.plugin like what i did for go.d.plugin, but do not see any executable like go.d.plugin. (Seems that it is embedded) ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/1X/090ee872283b91d5a80fc8ecdc9e00749d2c06bc.png) ---

I changed the permission (remove the “readonly” flag in mounts). But still have big problems: I have a lot of disks, but only see this _one_, and even this one has no disk space utilization. ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/1X/005b10af7f72585d686066762bdf2781e91a95ed.png) ---

There do exist one called `/host/mnt`, but I do not know what does it correspond to. Indeed, I have tens of PersistentVolumes, so I should at least see tens of disk\_usage info. ![image](https://canada1.discourse-cdn.com/flex029/uploads/netdata2/original/1X/27c5170c6f2bb726d21f96f0d74487ae02b6de48.png) ---

⚠ I am not a specialist, so don’t apply this on production, test it before. If you have some mounts inside the host `/mnt` and you want to see them inside the container, you could try `pod.spec.containers.volumeMounts.mountPropagation`, see [the docs](https://kubernetes.io/docs/concepts/storage/volumes/#mount-propagation). ```cmd 0 ~ $ kubectl explain pod.spec.containers.volumeMounts.mountPropagation KIND: Pod VERSION: v1 FIELD: mountPropagation DESCRIPTION: mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10. ``` There is `HostToContainer` option, perhaps it does the trick > `HostToContainer` - This volume mount will receive all subsequent mounts that are mounted to this volume or any of its subdirectories. > In other words, if the host mounts anything inside the volume mount, the container will see it mounted there. ---

@ilyam8 @vlvkobal Thanks for the replies! > If you have some mounts inside the host `/mnt` and you want to see them inside the container, you could try `pod.spec.containers.volumeMounts.mountPropagation` , see [the docs](https://kubernetes.io/docs/concepts/storage/volumes/#mount-propagation). Now it looks like: ```auto - name: mnt mountPath: /host/mnt mountPropagation: HostToContainer - name: mnt hostPath: path: /mnt ``` But still no luck… Nothing more appears on netdata website. > Please provide the contents of /host/proc/self/mountinfo from the inside of the netdata container.

Hi @vlvkobal @ilyam8 I wonder where there are any updates? IMHO this is an important feature because it is common to monitor whether the disks are full. Thanks! ---

@fzyzcjy i completely agree that the feature is important, we will try to find the solution. It is not clear at the moment how to statfs mountpoint which are not mounted into the netdata container. ---
