Backup Fail: Trying to add data in unsupported state
-
I updated XOA to the latest channel 5.97.0 and I still have the same issue. I can backup the VM without encryption and then it fails when encryption is enabled. We did purchase licensing from VATES so it's not an issue with being built from source.
-
I can confirm I am seeing the same thing with full a mirror full backup job to Backblaze B2 utilizing encryption. I am on Master, commit 732ca in my homelab. I have attached the backup log as well.2024-08-28T22_32_37.271Z - backup NG.json.txt

Thanks for the feedback, let me ping @florent internally

@nmadunich and same on XOA
stable? -
Hi,
what are the size of the failing VMs ? is there anything in the syslog before having the cipher error message ?
To be fair, uploading full backup ( > 50GB) , without knowing the size first is full of hurdles. And the xapi dont tell the size of the exports. Incremental backup with block storage completly circumvent this, by uploading separate blocks of known size
Regards

@olivierlambert Yes I get the same result on stable vs latest channel.
@florent The ones that fail do seem to be some of my larger VMs the Windows 10 VM that I have been testing with is about 88.3 GB used according to the OS.
All of my VMs are thin provisioned and our NetApp storage is using de-duplication so the size of the VHD on my storage is significantly less in this case it was about 3 GBs.
As a test I created a new storage volume without thin provisioning and de-duplication. I migrated the Disk to the new volume and the VHD is 103 GB. I also removed de-duplication and compression on my remote. I tried the backup again and it failed with the same error.
I do see some errors from the xensource.log around the time it fails and I attached those here.
I am editing my post after looking at the log file @Delgado posted mine are slightly different. I added mine for comparison. At some point during my testing the error also changed slightly and started stating VDI must be free or attached to exactly one VM. It appears after a failed backup it's not cleaning up the snapshots.

Hello,
My vms are about 150G each. I was using compression when I backed up the vm to the remote before mirroring it to the s3 bucket. I did end up changing to delta backups and the error did go away but I can create another normal backup and mirror it to the bucket again to see if I get the same results.
-
That's interesting
So it's only with full backup (XVAs) then. -
@olivierlambert yeah my experience is also that deltas run without error. Though what they're backing up exactly w/o a full in the remote is pretty questionable. I assume its a delta off of the snapshot full, where the snapshot is completed without issue and it's just the copy to encrypted remote that's failing.
These are definitely my larger VMs -- >100gb total disk.

Hi,
Same problem here.
Its an encrypted S3 remote to Backblaze.
Full mirror backup with selected VMs.
Small VM like Xen-Orchestra works. As soon as a large VM is added (approx. 500GB), the error occurs after about 3 hours.
Tried several times.xen-orchestra build from source
-
And with or without backup compression?
-
sorry... i forgot...
with zstd compression -
Can you try without it and report?
-
Yes.
iam making a non compressed backup now.
And then i try to mirror it with the mirroring job.Report follows... But uncompressed backup and upload will need some time
-
So, same error after 3 hours of uploading/mirroring an uncompressed backup to the encrypted backblaze remote.

I have the feeling it might be related to Backblaze and a potential timeout or something
-
Before this error, I had the following error:
transfer Start: 2024-09-11 15:14 End: 2024-09-11 16:07 Duration: an hour Error: no tomes available Start: 2024-09-11 15:14 End: 2024-09-11 16:07 Duration: an hour Error: no tomes available Start: 2024-09-11 15:14 End: 2024-09-11 16:07 Duration: an hour Error: no tomes available Type: fullI was able to fix this by giving the xen-orchestra vm more RAM.
I thought these were triggered by some kind of timeout.When the current error first occurred, I doubled the RAM again. Unfortunately that didn't help
-
Error: no tomes available
Never heard of this before. -
It seems to come from BackBlaze, eg https://github.com/mastodon/mastodon/issues/30030
Sadly, I'm not sure this is something we are able to fix on our side
-
It might be related to BackBlaze being overloaded at some point. Our advice:
- reduce backup concurrency
- reduce block concurrency during upload (
writeblockConcurrency) and merge (mergeBlockConcurrency) in theconfig.toml
