[Bug 1059827] Re: Non trivial grub2 installs no longer fit in small embed areas
Sorry, I did get a little confused over the sectors thing. The 63rd LBA sector is the starting point for the 0MB boundary of partitions usually. I wasn't thinking straight. I'm used to using the MB settings for partitioning instead. Anyhow, the normal Grub2 install for any partition that's not BtrFS can fit into the MBR area with no problem normally. However, a larger area is required if you're going to use a BtrFS partition since the data on how to read such a partition in Grub2 makes the boot program a bit larger than the MBR size. Recall that I said Core.img is particularly large. I'll have to check on my installation to see where I had to start it at later. But it is a problem that should be addressed or at least warned about in the installation. As for the installation report, it should mention that Grub2 failed to install properly and should return to the partitioning step to address the issue. Highlighting the issue may also be beneficial to users. However, with newer hard drives, they utilize 4K sector sizes to increase capacity. This should be taken into account in case the 512b emulation ceases. It's known as Advanced Format and can be a pain in the rear if you're not already familiar with it. This will make 256 sectors equal to 1 MB instead. Anyhow, I'll be sure to check on how I've managed to install BtrFS and where my partitions start and end so that I can toss together a sort of guideline for failsafes. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to a duplicate bug report (1266195). https://bugs.launchpad.net/bugs/1059827 Title: Non trivial grub2 installs no longer fit in small embed areas To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1059827/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs

[Bug 1059827] Re: Non trivial grub2 installs no longer fit in small embed areas
Actually, Phillip, BtrFS requires 2MB for a Grub2 installation. So, while you are correct that it does start at 1MB, the partitioner does have an error in not including that the rules for BtrFS are different. The normal 1MB is a part of the normal MBR rules. Since Grub2 requires some extra installation space for the BtrFS partition information, GParted should warn when BtrFS is used and a partition is started less than 2MB from the beginning of the drive. For everything else, 1MB works fine. So, this would be a problem with the partitioner not realizing the rules are different and the installer not seeing that the partitioner made a mistake and that Grub2 can not be properly installed inside of the 1MB space for a BtrFS partition. Ext4 and other partitions that are not BtrFS have no problem with the 1MB start point. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059827 Title: Non trivial grub2 installs no longer fit in small embed areas To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1059827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1059827] Re: Non trivial grub2 installs no longer fit in small embed areas
There is no need to reformat with Ext4. If you wish to use BtrFS for the Boot partition, it's recommended. Just tell the partitioner to start at the 1MB boundary instead of the first sector. To reiterate, you need an empty 1MB at the beginning of your drive to write to. I would call this an error with the partitioner/Ubuntu Installer instead of Grub2.

[Bug 1059827] Re: Non trivial grub2 installs no longer fit in small embed areas
** Description changed: Traditionally the first boot track of the disk was left unpartitioned. This area is used to embed the grub2 core.img file. The size of this area used to typically be 62 sectors. In recent years the typical size has changed to 2048 sectors to keep the partitions aligned to a 1 MiB boundary for performance reasons on SSDs and newer hard disks with 4KiB sector sizes. All but the most trivial configurations of grub no longer fit in the old 62 sector size embed area. This results in grub complaining that your embed area is unusually small. Upstream appears to have no desire to support such configurations, so this is unlikely to be fixed, but I will leave this bug report open for now. The workaround for the problem is to repartition the disk with modern partitioning tools that will align partitions to 1MiB, thus leaving 2048 sectors for the embed area. + + Another workaround is to setup a simple ext4 /boot partition rather than + try to boot directly from raid or lvm or btrfs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1059827 Title: Non trivial grub2 installs no longer fit in small embed areas To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1059827/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
