I noticed the patch later on. Now in devel.

Can we do something better than a crash? The BUG_ON is in alloc_tree_block, there's only one caller btrfs_alloc_free_block that handles errors, so it should be straightforward to fix.

Your ext* doesn't have enough free space to contain btrfs' metadata.

Hello, I am trying to convert an ext4 partition to btrfs using btrfs-convert. I am running Arch Linux with kernel 4.18.5 and btrfs-progs 4.17.1.

While trying to convert a ext4 filesystem to btrfs with the new btrfs-convert from btrfs-progs-4.6 I got the following error: create btrfs filesystem: blocksize: 4096 nodesize: 16384 features: extref, skinny-metadata (default) creating ext2 image file.
