Also, the man page seems to be for grub, not grub2 since the description has that the target directory is usually /boot/grub, not /boot/grub2. I realize that the man pages may not be up to date, but want to be sure.
    Code:
    # grub2-install /dev/xxx
    * that's how I always done it, but I don't have a UEFI system. The 'lot of option' are optional tweaks.

    To update grub.cfg it goes by
    Code:
    # grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
    Fedora docs: https://docs.fedoraproject.org/en-US...ng-with-grub2/ (I never know how up-to-date they are but this one seems ok).

    Okay, I'll give it a try. In my case, it would be grub2-install /dev/sda
    To update grub.cfg it goes by
    Code:
    # grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
    I've done that more than once and it did not make a difference.

    RH docs: https://access.redhat.com/documentat..._2_boot_loader
    Thanks. I'll check them out.

    Can the grub2-install be done on the running system, or do I need to boot from a live image DVD?

    Re: long boot time due to start job for uuid

    Hi Stephen. Sorry, but only now I read a bit this thread. First time I had replied in a hurry and this is not right

    Since you don't need hibernate functionality the you can safely NOT use the 'resume=' entry in /etc/default/grub . Delete that and re-generate you grub.cfg

    As for the swap failure, I think you don't need to mess with grub to test it. Since it's not being habilitated at startup, I guess you could test your changes with swapon and swapoff.

    Also check this thread in Arch linux forum:
    https://bbs.archlinux.org/viewtopic.php?id=248287
    And its wiki:
    https://wiki.archlinux.org/index.php...wap_encryption


    As for the grub thing, you only need a live cd if you don't have a boot loader installed and thus can't boot in your OS.

    Also, when you power on the system, press 'e' to edit the grub prompt and see if that fake uuid is there (you can delete it just for that boot).
    Another interesting resource re. grub, just for info, is

    I have already removed the hibernate entry. and I finally did get the encrypted swap working by moving it to /dev/sda (it had been on /dev/sdb). Unfortunately, I still get the minute and a half hang at boot and I can't find the uuid anywhere. It is not showing up at boot time (I tried the e to edit already). I ended up trying the grub2-install /dev/sda and it made no difference. Neither has the grub2-mkconfig. I'm not quite ready to do a full reinstall of Fedora, but I think that may be the only way to get rid of the non-existent uuid. This system has been through upgrades and changes of hardware, including addition and/or replacement of drives.

    Re: long boot time due to start job for uuid

    We don't have the knowledge, but it's something the OS wants to mount and doesn't find. It may have to do with LVM, encryption or something else.

    I suggest that you post in fedora's mailing list (main list is 'users' but there may be some other more specific). There is ask.fedora too but I don't know how's the activity there.

    Sure since you boot basically only once a day, try these other places as it can be something trivial to solve (like just finding the proper file to edit).

    I don't use LVM so that is ruled out. I do use encryption so that is a possibility. I don't even boot once a day. My computer stays on unless there is a kernel update. That is when I reboot. The only other times it is shut down are for an extended power outage (rare) or if there is a hardware issue I have to address, like the SSD that failed. It may be that the UUID belongs to a partition on that old drive that is now long gone. I'll have to go to the mailing list and see what I can find out.

    Re: long boot time due to start job for uuid

    I went on ask.fedoraproject.org and vgaetera there gave me the clue that helped diagnose this problem.

    Vgatera posted to try "sudo grep -i -r -e 'part of the UUID string that appeared' /etc" (minus the quotes, of course).

    grep -i -r -e d7280ed07bde /etc
    /etc/systemd/system/mnt-sdh1.mount:What=/dev/disk/by-uuid/66a98c2d-1a89-44a6-aa94-d7280ed07bde

    When I looked at this file, it turned out to be an artifact of when I was trying to set up Zoneminder using an external drive. That drive is no longer connected, so it is no surprise that the message was appearing. I deleted the file and boot times are back to being fast with no 90 second delay. I'm happy with this result. Hopefully, this will help anyone else who might encounter this problem
