[fuse-devel] Help with writing a block device based fs

[John S. <joh...@gm...>]

Hi all,

I'm trying to use FUSE to write a block device based file system, but
I can't find much documentation on it (or any at all, really). I've
looked back about a year's worth in the mailing lists, but couldn't
find much there. I've looked at the header files and sample file
systems, with not much luck either.

Basically, I want to treat it as if were the sort of file system you'd
have in the kernel: super block, inodes, blocks, etc. I'm just not
sure how to go about doing that.

>From what I understand, you need to use the open syscall to access it.
But then what? Do I just use the regular syscalls to seek around and
modify it? Would I use the low level FUSE API? Or use the API at all?
Are there any "gotchas" that I'm missing? I'm slightly lost.

Any pointers, tips, etc. would be greatly appreciated.
