I have an EeePC 901, which I thought I'd convert to BTRFS as a way of getting to understand the new filing system.
My machine has 3 partitions, 100MB for /boot, 4GB for /, and 15GB for /home.
I have successfully converted the 2 larger partitions with btrfs-convert, but when I try to convert the /boot partition I get the error message "block size too small".
Is there any way to convert this without doing a complete re-format/re-install?
Thanks in advance for any advice.

That, btrfs can't convert a so small partition
so you need to grow'd 'em
so I not recommend transform boot
thee can't get veneficies reals from that
Well, I suppose that this is somekind of signature, no?

To really get proper use out of btrfs, you should use a single filesystem and have your rootfs and /home as their own subvolumes. This is how btrfs is meant to be used.
But as you are taking the conversion route, unless you want to snapshot your /boot or something, you might just want to keep that as a normal traditional filesystem. Btrfs is pretty well supported by bootloaders these days, but the ext* filesystems are well tested and known to work extremely well. Typically the reason you hav a separate /boot in the first place is simply to ensure that your kernel and initramfs can be found by the bootloader. So if you are using a bios based bootloader from the offiical repos, both of those should support btrfs, so you could probably safely even just bot the contents back onto /.

Many thanks for your advice, and my apologies for the delay in responding.
As I'm just experimenting for now, I'll leave the /boot partition alone, then impliment a single filesystem next time I do a re-install. Your detailed explanation was great. WonderWoofy - much appreciated.
