OK, now managed to get a reproducer script to kick this bug even outside the early install context. Seems like we can force this bug by either remounting OR sync'ing and dropping caches.
Attached is the reproducer script. Run as root, we hit the error: cat: /root-tmp/etc/.pwd.lock: Input/output error dmesg: [ 42.415432] overlayfs: invalid origin (etc/.pwd.lock, ftype=8000, origin ftype=4000). ** Attachment added: "repro.sh" https://bugs.launchpad.net/ubuntu/bionic/+source/linux-hwe/+bug/1824407/+attachment/5302762/+files/repro.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1824407 Title: remount of multilower moved pivoted-root overlayfs root, results in I/O errors on some modified files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824407/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
