I couldn't find anything meaningful to me in a look at the kernel sources. I except maybe this is because inodes are being synchronized at the time the filesystem is being mounted, and are temporarily immutable? It's unclear, looking at this would require someone a lot more experienced in the kernel filesystem code to understand.
I'm closing the bug as Won't Fix, for the same reason as bug 1416396: the packages affected here aren't the packages we'd possibly apply changes to. If additional work is needed, please reopen against linux and include exactly what filesystem type is being used for the HTX tests (is it ext4? xfs?) so that a kernel engineer can look into it. ** Changed in: os-prober (Ubuntu Xenial) Status: Triaged => Won't Fix ** Changed in: os-prober (Ubuntu) Status: Incomplete => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1648561 Title: HTX (htxubuntu) DASD exercisers fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/1648561/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
