Suddenly getting 'Numerical result out of range' warning when backing up from Lustre source

Hi all,

  • Running restic 0.18.1
  • Backing up from a Lustre filesystem

So I have this backup cron routine that runs every night. Everything was running fine for months, but in the last few days I started getting those warnings:

error: incomplete metadata for <redacted_filepath>: xattr.list <redacted_filepath>: numerical result out of range

The strange thing is that couple of days ago, it started outputting this warning for a few files. Then yesterday, the number of files with the warning increased and today more files are giving this warning. And all this files exist in the source for more than a year and backup was all fine.

I saw this thread that the fellow user had the same warnings: Numerical result out of range - but since it was a SMB problem and I am backing up from Lustre, I decided to check if you could give me some light on this.

Anyways, thank you very much!
