Storage differences

[murgero]

@gloes Do you use a secondary disk by chance? I don't think ncdu will traverse other disks unless told via an argument.

[A Former User]

No, I use RAID 1.
I tried the following:
df -Th gives the following output:

58TB is wrong (it's the sum of the overlay), I only have 3.6TB.

ncdu / shows the following:

Maybe someone an explain this?

[nebulon]

Most likely the docker images take up all that space and tools like du are known to not report on this properly as mentioned in https://cloudron.io/documentation/storage/ Please use docker system df to determine the docker image sizes.

For further technical details if you are interested, there is some more explanation at https://stackoverflow.com/questions/50589971/diffrence-between-real-and-showed-by-docker-system-df-disc-usage

Further as stated earlier, you may just wait for the next release and the reporting within the dashboard is handling this already for you.

Is the situation any better with Cloudron 4.2?

[A Former User]

No there was no chnage. But as @nebulon mentioned, I think it has to do with docker images and that the image sizes can not be determined correctly. I will have a look at the links maybe I will find a explanation.

Now that we can see the size of Docker images in the GUI I'm even keener on knowing what the largest (green) "Other" part of the bar contains. I've compared the "Docker images" size with docker system df and it's correct.

[girish]

How big is the other? Do you have backups on the root file system as well?

[yusf]

@girish Other is 21.4 GB.

Sorry, I'm not sure. I use external backup now like a good boy but haven't always. How to check?

[girish]

That does seem a lot. Another user reported that backups of old mechanism are not deleted - https://forum.cloudron.io/topic/2026/can-i-remove-tarball-backups-in-snapshot . Can you check if you have old stale backups in /var/backups ?

I also have the green bar of death

@girish I've never changed backup method no there should not be any remains from that. I did have a directory from april sitting around at 8.6 GB though .

Removing that still leaves Other quite large though, so I'll appreciate more hints if you have any.
