Comments on: PUFFS for FreeBSD? http://blogs.freebsdish.org/anderson/2007/11/27/puffs-for-freebsd/ Just another FreeBSD Committers Blogs weblog Tue, 06 Jan 2009 15:40:51 +0000 http://wordpress.org/?v=2.6.5 By: Ale http://blogs.freebsdish.org/anderson/2007/11/27/puffs-for-freebsd/#comment-30 Ale Mon, 25 Aug 2008 17:53:58 +0000 http://blogs.freebsdish.org/anderson/2007/11/27/puffs-for-freebsd/#comment-30 Hello. I'm the maintainer of the sysutils/fusefs-ntfs (NTFS-3G) port, and it has some serious problems residing in the current fuse4bsd implementation (the author quickly fixed most of the problems that appeared, but now he is very busy at work IIRC). See the fusefs-ntfs/files/README.FreeBSD file, section "Known Problems". In short (I'm not a kernel programmer so please excuse me if I made some mistakes in the explanation), as FreeBSD uses vnode based IO and Linux uses full paths, it happens frequently that when a vnode is reused any filesystem using FUSE reports "file not found" or EAGAIN when using the filesystem (not the FUSE one, but the native UFS fs; as the problems is with the vnodes being reused). These problems can make it unusable when doing something else like compiling/extracting. Doing any kind of operations inside the FUSE filesystem does not produce the error, as it uses a user space caching library. If you make any progress on the port, I would like to hear about it. Also it would be nice if the code could be shared between FreeBSD and NetBSD then. Thanks, Ale Hello.

I have thought about helping with bluffs also, but that's not up to me. tarfs is still on the plate, but development slowed to a crawl over the last few months as I have joined a startup and it is eating most of my time. :)
