xfsrestore places all files restored from xfsdump into orphanage directory; root ino differs from mount dir ino

[Ryan Novosielski]

I am attempting to use xfsdump/xfsrestore piped together to rewrite my XFS filesystems for version 5 compatibility. This worked fine for two filesystems so far, 20G and 500G. The latest 300G filesystem I'm trying to rewrite does not work. See below (I interrupted it; it would continue on like that). To my relatively untrained eye, this appears to be this problem:

https://access.redhat.com/solutions/6601461

...but I don't see any bug for that in Ubuntu. It also does not mention xfsdump/xfsrestore version 3.1.9, only 3.1.8 and 3.1.10, so I don't know for sure that this is affected. There's not much information out there in general.

Is there a workaround or a fix pending?

These filesystems were probably written with Ubuntu 18.04 or earlier (I just recently did a fresh install, replacing Ubuntu 18.04 with Xubuntu 22.04, but I did run as early as 14.04 on this machine at one point, if I recall) -- the 2019 creation dates on the filesystem suggest that that's correct.

This is a fully up-to-date freshly installed copy of Xubuntu 22.04.4.

Downloaded the package from noble, which didn't have any unsatisfied dependencies on jammy thankfully.

This works fine:
