@MajorP93 Perfect, if the issue is confirmed resolved, we aim to release a patch early next week so no hurry

Hi again, we have found the most likely source of the issue and fixed it.

Could you checkout the fix_vhd_directory_merge branch and test that the backups take a reasonable length of time again ?

Thanks.

@MajorP93

Hi, yes this has clearly been a blind spot of our testing when we released the backups refactoring and our first step in fixing this issue is to add benchmarks to our testing suite to be sure this can't happen again.

Hi, thanks for the report we will look into this and get back to you ASAP.

@TechGrips Hi,
Unused XVA means a XVA file is not linked to any metadata (to remove a backup, we first remove the metadata file linked to it, then we remove the XVA), it should be removed by clean vm step. It is not an issue, just an information.

For the second warning "XVA might be broken", this is because the compressed file seems to be corrupted but we cannot be sure. We prefer to warn the user there may be an issue in the file. This should encourage to remake a backup.

Thanks @ph7, I'll try to have a look to understand what's going on

@flakpyro Hi, it seems it is a race condition between disk check and close, and disk transfer. That's why it is randomly happening. This is not an easy fix, we are trying to figure out a workaround.

Hi @Pilow,

Thanks for the report.

We are aware that there are many problems with the FLR. We would like to fix them but they are not easy to fix, and we can't give an estimation date for a fix. I've linked this topic to our investigation ticket.

For the moment, when FLR fails, we recommend to manually restore your files by following this documentation: https://github.com/vatesfr/xen-orchestra/blob/master/%40vates/fuse-vhd/README.md#restore-a-file-from-a-vhd-using-fuse-vhd-cli
