Hello,
I'm using BTRFS over LVM and after some time of usage (days or hours),
it just remounts itself, and I don't see the reason why, while it is
said to be fault-tolerant.
It is possible that I have bad sectors on the disk, though I don't
find it likely. Even then, I don't think bad sectors

It looks like you've shrunk the LV without first shrinking the
filesystem. Depending on how much you shrunk it by, the odds are
fairly good that significant chunks of the FS are

gigabyte (1024^3), and works the same with both tools. On smaller units
You have to watch for the rounding to extent size (4M by default).
Moreover, some could use:

Negative. GRUB2 has support for pretty much everything out there: ZFS, Btrfs,
LVM, LUKS, md raid 0, 1, 10, 5, 6. It will boot Btrfs
