Error when booting with rear uefi iso #2681
Comments
@RolfWeilen Please have a look at comment #1193 (comment) it may help you. Did you try to boot ReaR in Secure Boot to see if it changes the boot behavior? |
Hi secure boot shows the same problem.
I have attached the log. Best regards |
@RolfWeilen the error message
seems to mean that grub is out of memory. |
Hi |
|
@RolfWeilen are you able to recreate another ISO and test it? I suggest to omit |
By googling for "grub can't allocate initrd" I found in particular: https://bugzilla.redhat.com/show_bug.cgi?id=1572126
And that one is a more current issue
In general regaring the size of the ReaR recovery system |
Hi |
Hi Best regards |
@RolfWeilen If the ISO image created is meant to recover this system only then there is not need to load all firmware (kernel) modules. If there is a need to clone on slightly different hardware than it is a good idea to include all firmware (kernel) modules. |
Hi |
@jsmeix thanks for locating the related bug reports. "It appears to me that there have been quite some changes to the memory allocation stuff already which seem to have resolved the issue. It works with current git version. " indicates that maybe grub2 in RHEL 7 is too old and RHEL 8 could work (not sure if the fix is in RHEL 8, but it could be). |
Sorry, I see now this is RHEL 8, I got confused by Is it 32-bit UEFI by chance? Do you have a |
Yes, please address it to support, and also try on a different hardware. |
@RolfWeilen
in your #2681 (comment) above: You may need certain firmware to recover on exactly same hardware According to
you need some "hacks" to find out what exact firmware files |
Stale issue message |
We can close the case. I will test it again with RHL 8.5 and will then open the case by redhat. |
Hi @RolfWeilen, I saw a similar issue, for me it is fixed in grub2-2.02-121.el8 - try this build of GRUB2. |
Hi, I am facing the same issue with OL8.8 and grub2-efi-x64-2.02-148.0.1.el8.x86_64. Has anyone find a better fix in the meantime than excluding the firmware files? |
@dragon299 I was seeing the same issue on a HP ProLiant DL180 Gen9 machine. Is your problem also related to HP hardware? In may case it seems to be solved by a firmware upgrade. The error was also fixed (without a firmware upgrade) in grub2-2.02-121.el8 and then reappeared in grub2-1:2.02-142 . It is apparently related to this entry in %changelog (
So I suggest to upgrade the firmware, of if this is not possible or does not help, to downgrade GRUB to a version between 2.02-121.el8 and grub2-1:2.02-141.el8. |
