Solved Graphs error with Volumes

[A Former User]

@girish Huh weird...

Now I see this on the Disk usage tab under "System Info". My mounts seem to work just fine as I can now access the volumes on them and everything in the apps work.

@atridad Can you try restarting graphite under Services and wait for 5-10 minutes (to collect the disk information) ? But yeah, ideally it should not barf like that....

[A Former User]

@girish kk trying that. Its not functionally causing issues but just thought I should report.

On a side note, I changed the text for this page now from this "Cloudron in the wild" to

"You are seeing this page because this domain points to Cloudron server IP but no app is installed on that domain" (which is the only reason you should see this page).

@girish Nice, thanks! Oh and it seems that error is back.

Seems like it has an issue with my hard drive mount??? sdc1 is the partition I am using on my 2TB HDD (where my music, movies, and shows live)

[girish]

@atridad Oh, I think I know the issue and it's probably related to https://git.cloudron.io/cloudron/box/-/issues/786 . Let me test this and check if that's the bug or not. Basically, collectd profiles for volumes are not created on restore. I just left this as a known bug in 6.3 but looks to be worthwhile fixing.

Of course a workaround is to delete the volume and create it again.

@girish oh so I actually don't even have the drive set up as a volume. My setup is as follows:

Main 1TB SSD
2TB SSD manually mounted to /mnt/ssd, and has my next cloud instances on it
2TB HDD manually mounted to /mnt/ssd
Volumes for music, movies, and songs pointing to /mnt/hdd/media/<type of media>

@atridad Do you still get this error? I think I will have to debug on your server to know what the problem is. If it's a problem, can you write to us at support@cloudron.io?

[A Former User]

@girish yeah still a problem. And sure I can send in a ticket.

The full stack trace is:

The last line gives a hint that the graphite file is corrupt. So, I removed all the whisper files in /home/yellowtent/platformdata/graphite/whisper/collectd/localhost/df-sdc1 and graphs seems to work after that.

@atridad Maybe a good idea to check the health of the hard disk ? Also, since we hit the systemd issue on the same server.
