Package: grub2
Version: 2.06-12
Severity: normal
Dear Maintainer,
grub2 686 machines do not see partitioins with big offset from start of the disk. It has no issues see
partitions at the begining of the disk.
/dev/sda1 34 2047 2014 1007K BIOS boot
/dev/sda2 2048 3369748479 3369746432 1.6T Linux filesystem
/dev/sda3 3503966208 3638183935 134217728 64G Linux filesystem
/dev/sda4 3638183936 3772401663 134217728 64G Microsoft basic data
/dev/sda5 3772401664 3906619391 134217728 64G Linux filesystem
/dev/sda6 3906619392 3907028991 409600 200M EFI System
/dev/sda7 3369748480 3503966207 134217728 64G Linux filesystem
I tried sda7 as my debian partition and start from following:
* luks1/2+btrfs
* btrfs
* ext4
grub ls showing correct (hd0,gpt1-7). At least part_gpt works. Also grub does
see by sda2 btrfs parittion and it's content. But sda7 partition does not work!
1) 'cryptomount -a' report no erros and exit for booth luks1 and luks2
2) saying unknown partition about btrfs formatted drive
3) syaing unknown partition about ext4 formatted drive
It looks like grub simply does not recognize big offset partitions. I tried
boot using livecd debian 686 and have no issue mounting sda7 partition.
Full logs including dmesg and cpuinfo (livecd; chroot /dev/sda7).
