grub-install problem after trixie upgrade
I have just upgraded from bookworm to trixie. An AMD FX (64 bit) machine.
The main disk is 2 disks in a RAID-1 pair (mirroring). The boot partition is
/dev/md0 that is built thus:
md0 : active raid1 sda1[0] sdb1[1]
510976 blocks super 1.2 [2/2] [UU]
I get an error installing grub. I do not understand it let alone know how to
fix it. Note that the error happens for sda but not sdb:
# grub-install --target=i386-pc /dev/sda
Installing for i386-pc platform.
grub-install: warning: You have a short MBR gap and use advanced config. Please increase post-MBR gap..
grub-install: warning: your core.img is unusually large. It won't fit in the embedding area.
grub-install: error: embedding is not possible, but this is required for RAID and LVM install.
# grub-install --target=i386-pc /dev/sdb
Installing for i386-pc platform.
Installation finished. No error reported.
My core.img:
-rw-r--r-- 1 root root 33386 Aug 11 01:14 /boot/grub/i386-pc/core.img
The disks are DOS partition table format not GUID as the hardware/BIOS does not
understand GUID - I bought it in 2012.
There might be some clues here but I cannot reach it: https://lists.gnu.org/archive/html/grub-devel/2020-03/msg00134.html
Can anyone offer any illumination ?
Thanks
Another problem is that it is 500 MB, trixie recommends that it should be 768
MB; a problem that I shall worry about another day.
