Fixes the EIO error experienced by some exporting mergerfs over NFS. Turns out it was both a kernel bug and a mergerfs bug. Hence why it took so long to track down.
For those who used export-support=false in v2.40.0 please stop doing so.

Provides a workaround for those using NFS and getting EIO errors. Set the new option `export-support=false`.
It is caused by an apparent kernel bug. Till the bug is fixed this seems to be the only workaround (besides not using NFS). More details are in the README in the new "Remote Filesystems" section.

Main feature is the addition of an experimental LD_PRELOAD library which can be used with dynamically linked software to improve file IO by leveraging mergerfs to create/open the file, and then reopening the original file.

A big list of "quality of life" features.
There hasn't been much in the way of public updates for mergerfs the past several months. I did start working on major rewrites of mergerfs for v3 but got side tracked with 3DO related projects. Mostly tooling to help with media conversion as well as an easier to use development toolkit. I hope to get back to mergerfs soon.

Have listed out some ideas I have for mergerfs v3.X. Please check it out and throw in some ideas if you have them.
2021-02-05 01:46:10 +0000 UTC View PostI apologize for posting here later than other places.
I've released 2.32.x recently with a few internal updates and bug fixes.

There hasn't been much going on publicly with mergerfs but I have spent a bunch of time playing with different ideas. I'm an iterative style developer where I tend to rewrite features a few times before committing them. ...

Took a bit longer to get out than I had hoped. I was fooling with a few other features that I considered including but since those are still baking I figured I'd release it as it was.
Nothing too exciting.

Hope everyone is well. Sorry for lack of updates lately. Been doing a lot of random experimentation but haven't made too much progress with any particular project of mine.
But it wasn't all just messing around. I finally did a proper release of scorch with a few new features.

Thank you to patrons. Thank you users.

For those interested in my 3DO related work...
1) Created a new website in collaboration with Bugo The Cat / Optimus to document as much as possible about the 3DO and M2 with regards to development. Both for the system itself as well as for emulating the systems. Optimus is working on a homebrew tutorial and created a tutorial for creating 3DO compatible Cinepak videos.
2) I've been working on adding some feat...

This is a few weeks old but I was on the Jupiter Network's Extras Show talking about mergerfs back in October. I go into some of the technical aspects of mergerfs. Might be interesting for some.

Ashish Bijlani and Umakishore Ramachandran of Georgia Institute of Technology have been working on an extension to FUSE to allow using eBPF which can help move some of the high latency logic that often slows down a FUSE based filesystem into the kernel and thereby improving performance.
I'm still digging into t...
2019-07-11 11:06:47 +0000 UTC View PostI've added a bunch of new features and enhancements lately and I've got a list of things to investigate. Wanted to lay them out here and see if there are anything users might be looking for.
* readdir_plus support: Will be easy to add. Probably come in 2.29. Should improve performance of `ls -lh` and the like. It combines the request for files with the metadata rather than separate steps.
* increasing readdir message size: The FUSE kernel module currently hardcodes the message siz...

I just released 2.28.0 which has a few significant changes. In Linux 4.20 there were a few features added that I now take advantage of. It can now cache symlinks and readdir (directory listing). When combined with increased `cache.attr` and `cac...
2019-06-06 00:58:13 +0000 UTC View PostAre there any features people are looking for? Tutorials / howtos they'd like to see?
Some things I'm considering:
* statfs caching: statfs calls are on the expensive side and done regularly but on average the data doesn't change drastically between each call. A cache may help improve performance with certain usage patterns.
* stat caching: less likely to be as useful due to the number of possible values and typical use patterns.
* writeback caching: found in libfuse3. may he...
2018-12-05 21:19:13 +0000 UTC View PostEarlier this year I took a break from mergerfs and took over maintenance of the libretro 4DO core. I cleaned up the code, fixed misc bugs, and made a few quality of life improvements. There is still a lot that could be done to improve performance and compatibility but lack of documentation and complexity of the existing code makes that tough. So I took a break and started working on mergerfs again. As you may have noticed I 2018-12-05 16:07:49 +0000 UTC View Post
