Of course if this is not root, you can just unmount it to do the btrfs check. But if it's root, an alternative to usb booting is to do it from the initramfs. But you need to make sure the initramfs contains the right version. To do that, boot with parameter rd.break=cmdline and then: # btrfs --version Btrfs v3.18.1 ## OK Good I can continue, even if this is the 3.17.8 kernel, it's fine. # btrfs check --repair <dev> # reboot -f I did this with a regular initramfs, I didn't try the rescue initramfs which almost certainly will have an older version, probably 3.17. -- Chris Murphy -- users mailing list users@lists.fedoraproject.org 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?
