Disk space usage seems incorrect on external disk
-
@d19dotca said in Disk space usage seems incorrect on external disk:
@girish Out of curiosity... how often will it check for updated disk sizes by default without manual intervention?
Currently, it's manual. You have to click the refresh button on the top right to trigger a computation. I guess we can make this periodic for next release, but the issue was this value is always getting "out of date" and thus we weren't sure if there is value in periodic computation (besides, this causes much disk spin).
-
@girish - I just updated and there still seems like something wrong with the calculation...169 GB used at the top of the external disk but "this disk contains" only shows 156 GB used? How is there such a big difference there when all that's on the disk is backup files from Cloudron?
Does the external disk get recalculated too when I refresh it from the top?
-
Update:
For my main disk...
df -Hshows this for vda1 / (root):/dev/vda1 182G 100G 73G 58% /Yet Cloudron shows the following: (108 GB used)
Where is it getting that extra nearly 9 GB used from? The total disk size is close enough (181.37 GB vs 182 GB shown from command), it's just the usage part that seems quite inaccurate, especially if we're using si units this time with version 7.3.2.
For my backup disk it's similar situation:
df -Hshows this for vdb1 (cloudronbackup):/dev/vdb1 253G 205G 36G 86% /mnt/cloudronbackupYet Cloudron shows this: (217 GB used above graph, 204 GB used below)
In this case for the external backup disk, the lower Used number of 204.51 GB is pretty close to the 205 GB from the command, so that seems accurate, however in that case where is that extra ~12 GB coming from for the above-graph used number?
There seems to be a lot of discrepancies in the calculations here still, unfortunately. Cc @girish

Btw, I think it'd be nice if the GUI showed free space too in an easy manner instead of having us do the math ourselves
haha. For your consideration...
Or maybe it could be closer to how Apple displays it where the used bit is how you have it but then in the graph itself the free bit is the available space left?

@girish - I noticed you marked this as Solved 4 days ago, but I don't believe this has actually been solved.
There's a pretty large discrepancy in usage for my external disk as seen in earlier screenshots, and I don't see that having been resolved yet.
For example, "used" under the "this disk contains:" section is 204 GB, but then the graph part shows 217 GB used. Seems like a defect that there's multiple different "used" numbers presented, and by quite a few GBs too (approximately 5 - 20 GB discrepancy).
Even in your own screenshot from earlier, the total underneath the graph adds up to about 36 GB but yet above the graph it shows 41 GB used (this is the minimum difference I've seen so far but still a large 5 GB difference in used space).

@d19dotca Can you give us the output of
df -B1 --output=source,fstype,size,used,avail,pcent,target? This is the command used to get disk information.The du information is got from the du command. Can you check if running
du -DsB1 <path>matches with what you see in graph for the apps and backup directory ?Finally, for docker itself, the size comes from
docker system dfoutput. -

The output for that df command is below (my backup disk is currently full, need to expand that in a minute, haha):

Hopefully that clarifies the issue a bit by showing the discrepancies between what's shown in the UI vs what's shown in the command line terminal on the VM.

@d19dotca actually I think we need a more direct look at your system to figure out what is happening there. If you like, can you enable remote SSh support for us and send us a mail with your dashboard domain to support@cloudron.io ?
-
@nebulon No problem at all. I just enabled access for you and submitted the ticket for it through the Support page in Cloudron. Hope that helps.
@d19dotca so the root cause for the discrepancy is the reserved disk space for the root user on ext4. Some info on that at https://wiki.archlinux.org/title/ext4#Reserved_blocks
This is also why
dfshows a discrepancy between the values. I have fixed up the UI now to reflect exactly whatdfreports to avoid confusion. -

Or is that related to something else? Just wanting to better understand it. Regardless though, thanks for fixing it!
