Backup before upgrade failing.

I think then that you have corrupt media somewhere in that Mastodon instance. I've come across this, too. An app used to backup, then doesn't, and so often, despite few clear log guidance, I could always trace it back to some corrupt jpg or png or mov or something which was making the backup hang. Those few "out of memory" log entries suggest this, too. Something in that Mastodon instance is making the whole backup process hang. So, I am not sure it is Cloudron (you said you have others already running... so not Cloudron).

FWIW, I have this corrupt media issue on Cloudron, but also on other servers using different types of backup approaches. It's almost always some weird bit of media, or not enough memory.

@mhgcic I think akamai is misleading us with the AccessDenied message. Can you tell me the size of the 717035b5-ff81-4367-b920-d0619a532992 app ? My suspicion is that multi-part file copy is failing. Is it above 1GB? You can get the exact size with du -hcs /home/yellowtent/appsdata/717035b5-ff81-4367-b920-d0619a532992

Can you also tell me which linode region you are using for storage? I can quickly try this myself first before debugging on your setup .

@girish I have messaged you the details, I have also sent 2 links one to a manual backup log and an auto backup log from the app having the issue.

But this is where it seems to go wrong.

I have found a work around and maybe confirmation on whats causing the issues.

I changed these

screenshot-my.apes-volunteer.net-2024.02.04-07_54_33.png

The backups still failed.

I changed from tarball to rsync and it is backing up fine.

This confirms it has to do with the creation of files via splitting them, and permissions on the server stopping upload to s3 maybe?

It may take longer for backups to perform for the moment, but I will keep it as rsync for the moment.

girish

@mhgcic thanks for the update. I will take a look into testing with the Frankfurt region for multipart copies.

girish

mm, it works for me with 7GB file sizes in Frankfurt.

If you hit this again, contact us on support@cloudron.io, so we can debug this on the server.

mhgcic

@girish

Thanks, I really feel like it is something going on on the cloudron server not so much s3, I have other apps backing up just as this one app.

I have been investigating further.

I removed relays, waited 2 day, and put backups back to the Tarball method.

The app size has gone from just over 10GB to approx 2GB. Backups are now working as a tarball.

So I think

A file created from one of the relays is causing the issue. Hence now all relays have been removed backups now work.
The creation of the slitted backup files does not have the correct permissions at the time of creation to upload to s3.
Timeout?
One other possibility is I had some relays disabled as they were producing Chinese language posts. Could these relays being disabled be causing an issue with uploading backup?

I am going to readd relays until the issue comes up again.

@mhgcic I suspect this is to do with the final file size of the back up. Atleast, per the initial failure logs, the backup was created and it was also uploaded fine to s3. Where it was failing is the "remote copy" part. This part is known to be flaky across s3 providers. I am now testing > 10GB. Yesteday, I stopped at 7GB!

@girish The backup was about 11GB Try 11GB.

To follow up, 11GB worked fine too.
