Looks like you need to shrink lvm a bit. EFI needs a partition
formatted to one of the FAT family filesystems, with no additional
software needed to access it, so no encryption or LVM. The size
recommendation for Linux is 1GB minimum. It's generally advised to
keep it near the beginning of large discs.
You have Boot partition and EFI partition mixed up. They are
different things.
No, I wasn't considering the /boot (minus /boot/EFI) partition at all.
EFI partition have to be formatted to FAT32, but its safe and
sufficient size could be even 100MB, because only UEFI executable
binaries go there.
Yes, that's what MS recommends, but MS notoriously under-specifies
various minimum requirements and has done for decades.
The Internet generally recommends 100-500MB. There are recommendations
for 1GB.
The points to consider are that nobody knows what /boot/efi might need
to contain in the future, in addition to the current files, and given
modern drive sizes, the odd GB here or there is a rounding error. If
you reach the point where 900MB less spare space is really becoming an
issue, it's time you moved to a bigger drive or added more LVM space.
Well, I thought the output from "lsblk" and "gdisk" was speaking for
itself. That is roughly 30MB of space consumed for two OSs installed
side-by-side.
It was like that since the inception of UEFI (20 years ago?) and I
really can't think of any useful UEFI-native utilities that could fill
up even 500MB of EFI partition space.
UEFI binary of Memtest86+ is AFAIR less than 1MB.
