Dave Chinner wrote: So bulkstat got EINVAL returned for and inode that it was looking up. That implies that it was racing with an unlink, which is what the above commits catch and prevent. Can you run xfsdump with full debug output (-v 5) so we can see what inode is being operated on when this failure occurs? Thank you so much Dave! Please find the trace output here in zipped format: http://www.lueckdatasystems.com/pub/ldsbackup.trace.log.zip I chose to trace the "data" backup that actually had some size to it.
