Grub menu is hidden by default in ubuntu installations

[Alexander Bozhenko]

By default fuel is deployed with these options:

root@node-3:/etc/default# grep TIMEOUT /etc/default/grub
GRUB_HIDDEN_TIMEOUT=5
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10

First two mean that menu is not showed until you press a key.
When connecting via ipmi console it takes time for it to show something after video mode changed.
So it may be hard to catch right moment to press the key to see grub menu if one wants to select a different kernel.

Please comment this two options:
#GRUB_HIDDEN_TIMEOUT=5
#GRUB_HIDDEN_TIMEOUT_QUIET=true
To make it easier to see the menu(with 10 sec timeout) by default.

@Alexander Bugs can be moved to Confirmed status only by the team that is currently assigned

[Roman Vyalov (r0mikiam)]

@reassign to the python team , because this bug related to the fuel-agent

[Alexander Bozhenko (alexbozhenko)]

Not sure If I understand correctly what fuel-agent is, but I meant grub menu on already deployed node, not on bootstrap.

    Increase all the grub_timeout defaults to 10sec

    This increases the timeout value and adds the ability in the
    IPMI session to catch the moment and press a key to see the
    grub menu to choose a different kernel.

Thank you, increasing timeout may help, but why not to set
 GRUB_HIDDEN_TIMEOUT_QUIET=fasle
?

Please try to login to ipmi console on server located several thousands kilometers away using poor connection, and you will see that to catch the moment for pressing the key to see grub menu is pain.

In my opinion it won't hurt to set GRUB_HIDDEN_TIMEOUT_QUIET=false to make menu visible by default.

Hello, Alexander Bozhenko (alexbozhenko),

if you unsatisfied with how it was fixed or really just thinking that the bug is still presented, feel free to move this bug back to confirmed state. (Not sure if you have enough rights for that, so if this is the case, just leave a message here about that, i'll change the status.)

[Alexander Bozhenko (alexbozhenko)]

Ok, moved to confirmed.

    Fix GRUB_TIMEOUT usage and remove GRUB_HIDDEN_TIMEOUT

    This commit removes the GRUB_HIDDEN_TIMEOUT options which shouldn't
    be used together with GRUB_TIMEOUT set to a non-zero value. Also, it
    fixes the bug and from now the Grub menu will always be shown.
