<h2 id="preloadso">preload.so</h2>
|
|
<p>EXPERIMENTAL</p>
|
|
<p>For some time there has been work to enable
|
|
<a href="../config/passthrough/">passthrough</a> IO in FUSE. Passthrough IO would
|
|
allow for near native performance with regards to reads and writes (at
|
|
the expense of certain mergerfs features.) In Linux v6.9 that feature
|
|
made its way into the kernel however in a somewhat limited form which
|
|
is incompatible with aspects of how mergerfs functions and took longer
|
|
to implement as a result. This preloadable library was created as an
|
|
alternative to the FUSE <a href="../config/passthrough/">passthrough</a>
|
|
integration.</p>
|
|
<p><code>/usr/lib/mergerfs/preload.so</code></p>
|
|
<p>This <a href="https://man7.org/linux/man-pages/man8/ld.so.8.html#ENVIRONMENT">preloadable
|
|
library</a>
|
|
overrides the creation and opening of files in order to simulate
|
|
passthrough file IO. It catches the open/creat/fopen calls, has
|
|
mergerfs do the call, queries mergerfs for the branch the file exists
|
|
on, reopens the file on the underlying filesystem and returns that
|
|
instead. Meaning that you will get native read/write performance
|
|
because mergerfs is no longer part of the workflow. Keep in mind that
|
|
this also means certain mergerfs features that work by interrupting
|
|
the read/write workflow, such as
|
|
<a href="../config/moveonenospc/">moveonenospc</a>, will no longer work.</p>
|
|
<p>Also, understand that this will only work on dynamically linked
|
|
software (a that dynamically linked with the same general libc version
|
|
as the software being used with it.) Anything statically compiled will
|
|
not work. Many GoLang and Rust apps are statically compiled.</p>
|
|
<p>The library will not interfere with non-mergerfs filesystems. The
|
|
library is written to always fallback to returning the mergerfs opened
|
|
file on error.</p>
|
|
<p>While the library was written to account for a number of edgecases
|
|
there could be some yet accounted for so please report any oddities.</p>
|
|
<p>Thank you to
|
|
<a href="https://github.com/nohajc/mergerfs-io-passthrough">nohajc</a> for
|
|
prototyping the idea.</p>

<p><strong>NOTE:</strong> Since a container can have its own OS setup there is no

guarentee that <code>preload.so</code> from the host install will be compatible
