Since 3.17.8 didn't get this patch, and 3.17 is EOL, it won't ever get it. Looks like the patch is in 3.18.3, and 3.14.29. And it's easier to go with 3.18.3, which is in updates-testing. Next you should reboot from Fedora 21 live media, and 'dnf upgrade btrfs-progs' so that you have btrfs-progs 3.18.1, which is stable. And use 'btrfs check --repair' in case there are any missing files, this should find it. After this, you'd update the backup again in case the first one lacks the missing files. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
