|
|
<h2 id="i-modified-mergerfs-config-but-it-still-behaves-the-same">I modified mergerfs' config but it still behaves the same.</h2>
|
|
<p>mergerfs, like other filesystems, are given their options/arguments at
|
|
mount time. You can not simply modify the <a href="../../quickstart/#usage">source of the
|
|
configuration</a> and have those settings applied
|
|
any more than you would for other filesystems. It is the user's
|
|
responsibility to <a href="../../setup/upgrade/">restart</a> mergerfs to pick up
|
|
the changes or use the <a href="../../runtime_interfaces/">runtime interface</a>.</p>
|
|
<p>NOTE: the <a href="../../runtime_interfaces/">runtime interface</a> is <strong>just</strong>
|
|
for runtime changes. It does <strong>NOT</strong> save those changed values
|
|
anywhere.</p>
|
|
<h2 id="why-are-all-my-files-ending-up-on-1-filesystem">Why are all my files ending up on 1 filesystem?!</h2>
|
|
<p>Did you start with empty filesystems? Are you using an <code>existing path</code>
|
|
policy such as <code>epmfs</code>?</p>
|
|
<p>If starting with a set of empty filesystems such a policy will select
|
|
only 1 filesystem when the first directory is created. Anything
|
|
created in that directory will be placed on the same branch because
|
|
that is the point of such a policy. That is the expected behavior.</p>
|
|
<p>This may catch users off guard but the point of those <code>existing path</code>
|
|
policies is to preserve the directory layout and you need to consider
|
|
what that means one event at a time.</p>
|
|
<p>To "fix" this situation change the policy. Most users <a href="../configuration_and_policies/#how-can-i-ensure-files-are-collocated-on-the-same-branch">have little
|
|
reason</a>
|
|
to use such a policy. See the <a href="../../quickstart/">quick start guide</a>
|
|
and <a href="../configuration_and_policies/">FAQ</a> for policy recommendations.</p>
|
|
<h2 id="why-do-i-get-an-out-of-space-no-space-left-on-device-enospc-error-even-though-there-appears-to-be-lots-of-space-available">Why do I get an "out of space" / "no space left on device" / ENOSPC error even though there appears to be lots of space available?</h2>
|
|
<p>First make sure you've read the sections about <a href="../../config/functions_categories_policies/">policies, path
|
|
preservation, branch
|
|
filtering,</a> and the
|
|
options <a href="../../config/minfreespace/">minfreespace</a>,
|
|
<a href="../../config/moveonenospc/">moveonenospc</a>,
|
|
<a href="../../config/statfs/">statfs</a>, and
|
|
<a href="../../config/statfs/#statfs_ignore">statfs_ignore</a>.</p>
|
|
<p>mergerfs is simply presenting a union of the content within multiple
|
|
branches. The reported free space is an aggregate of space available
|
|
within the pool (behavior modified by <code>statfs</code> and
|
|
<code>statfs_ignore</code>). It does not represent a contiguous space. In the
|
|
same way that read-only filesystems, those with quotas, or reserved
|
|
space report the full theoretical space available. Not the practical
|
|
usable space.</p>
|
|
<p>Due to using an <code>existing path</code> based policy, setting a <a href="../../config/branches/#branch-mode">branch's
|
|
mode</a> to <code>NC</code> or <code>RO</code>, a
|
|
filesystems read-only status, and/or <code>minfreespace</code> setting it is
|
|
<a href="../../config/functions_categories_policies/#filtering">perfectly
|
|
valid</a> that
|
|
<code>ENOSPC</code> / "out of space" / "no space left on device" be returned when
|
|
attempting to create a file despite there being actual space available
|
|
somewhere in the pool. It is doing what was asked of it: filtering
|
|
possible branches due to those settings. If that is not the behavior
|
|
you want you need to modify the settings accordingly.</p>
|
|
<p>It is also possible that the filesystem selected has run out of
|
|
inodes. Use <code>df -i</code> to list the total and available inodes per
|
|
filesystem.</p>
|
|
<h2 id="why-isnt-the-create-policy-working">Why isn't the create policy working?</h2>
|
|
<p>It probably is. The policies rather straight forward and well tested.</p>
|
|
<p>First, confirm the policy is configured as expected by using the
|
|
<a href="../../runtime_interfaces/">runtime interface</a>.</p>
|

|
|
</span></code></pre></div>
|
|
<p>Second, as discussed in the <a href="../../support/">support</a> section, test the
|
|
behavior using simple command line tools such as <code>touch</code> and then see
|
|
where it was created.</p>
|
|
<div class="language-shell highlight"><pre><span></span><code><span id="__span-1-1"><a id="__codelineno-1-1" name="__codelineno-1-1" href="#__codelineno-1-1"></a>$<span class="w"> </span>touch<span class="w"> </span>/mnt/mergerfs/new-file

|
|
</span></code></pre></div>
|
|
<p>If the location of the file is where it should be according to the
|
|
state of the system at the time and the policy selected then the
|
|
"problem" lies elsewhere.</p>
|
|
<p><a href="../technical_behavior_and_limitations/#how-does-mergerfs-handle-moving-and-copying-of-files">Keep in
|
|
mind</a>
|
|
that files, when created, have no size. If a number of files are
|
|
created at the same time, for example by a program downloading
|
|
numerous files like a BitTorrent client, then depending on the policy
|
|
the files could be created on the same branch. As the files are
|
|
written to, or resized immediately afterwards to the total size of the
|
|
file being downloaded, the files will take up more space but there is
|
|
no mechanism to move them as they grow. Nor would it be a good idea to
|
|
do so as it would be expensive to continuously calculate their size
|
|
and perform the move while the file is still being written to. As such
|
|
an imbalance will occur that wouldn't if the files had been created
|
|
and resized one at a time.</p>
|
|
<p>If you wish to reduce the likelihood of this happening a policy that
|
|
does not make decisions on available space alone such as <code>pfrd</code> or
|
|
<code>rand</code> should be used.</p>
|
|
<h2 id="why-cant-i-see-my-files-directories">Why can't I see my files / directories?</h2>
|
|
<p>It's almost always a permissions issue. Unlike mhddfs and
|
|
unionfs-fuse, which accesses content as root, mergerfs always changes
|
|
its credentials to that of the caller. This is done as it is the only
|
|
properly secure way to manage permissions. This means that if the user
|
|
does not have access to a file or directory than neither will
|
|
mergerfs. However, because mergerfs is creating a union of paths it
|
|
may be able to read some files and directories on one filesystem but
|
|
not another resulting in an incomplete set. And if one of the branches
|
|
it can access is empty then it will return an empty list.</p>
|
|
<p>Try using <a href="https://github.com/trapexit/mergerfs-tools">mergerfs.fsck</a>
|
|
tool to check for and fix inconsistencies in permissions. If you
|
|
aren't seeing anything at all be sure that the basic permissions are
|
|
correct. The user and group values are correct and that directories
|
|
have their executable bit set. A common mistake by users new to Linux
|
|
is to <code>chmod -R 644</code> when they should have <code>chmod -R u=rwX,go=rX</code>.</p>
|
|
<p>If using a <a href="../../remote_filesystems/">network filesystem</a> such as NFS
|
|
or SMB (Samba) be sure to pay close attention to anything regarding
|
|
permissioning and users. Root squashing and user translation for
|
|
instance has bitten a few mergerfs users. Some of these also affect
|
|
the use of mergerfs from <a href="../compatibility_and_integration/">container platforms such as
|
|
Docker.</a></p>
|
|
<h2 id="why-are-file-moves-renames-linkshardlinks-failing">Why are file moves, renames, links/hardlinks failing?</h2>
|
|
<p>mergerfs fully supports rename and link functions to the degree that
|
|
is possible in a union filesystem. Problems related to rename and link
|
|
are almost exclusively due to incorrect setup of software or poorly
|
|
written software.</p>
|
|
<h3 id="docker-podman-and-other-container-runtimes">Docker, Podman, and other container runtimes</h3>
|
|
<p>Keep in mind that <a href="../../config/rename_and_link/">rename and link</a> will
|
|
<strong>NOT</strong> work across devices. That includes between the original
|
|
filesystem and a mergerfs pool, between two separate pools of the same
|
|
underlying filesystems, or bind mounts of paths within the mergerfs
|
|
pool. The latter is common when using Docker, Podman, or other
|
|
container runtimes. Multiple volumes (bind mounts) to the same
|
|
underlying filesystem are considered different devices. There is no
|
|
way to link or rename between them despite them binding to the same
|
|
underlying filesystem. Neither mergerfs or any other filesystem has a
|
|
say in this behavior as the kernel is erroring out before the request
|
|
even gets to the filesystems in question.</p>
|
|
<p>To work around this situation the highest directory in the mergerfs
|
|
pool that includes all the paths you need is what should be bind'ed
|
|
into the container if you want links and rename to work between the
|
|
paths in question.</p>
|
|
<p>This is a common problem for users of Radarr, Sonarr, Lidarr,
|
|
etc. when they use the default volume mount options suggested by
|
|
projects like
|
|
<a href="https://docs.linuxserver.io/images/docker-radarr/?h=radarr#docker-compose-recommended-click-here-for-more-info">LinuxServer.io</a>. Do
|
|
not use separate "movies" and "downloads" volumes.</p>

<h3 id="path-preserving-create-policies">Path-Preserving Create Policies</h3>
|
|
<p>As described in the <a href="../../config/rename_and_link/">rename and link</a>
|
|
docs if a path-preserving create
|
|
<a href="../../config/functions_categories_policies/">policy</a> is configured
|
|
then mergerfs, in order to follow that restrictive policy, must return
|
|
an error
|

(<a href="https://man7.org/linux/man-pages/man2/rename.2.html">EXDEV</a>) if the

<p><a href="../configuration_and_policies/#how-can-i-ensure-files-are-collocated-on-the-same-branch">Most
|
|
users</a>
|
|
do not have a need for path-preserving policies but if you intend on
|
|
using path-preserving policies you must accept that <code>EXDEV</code> errors are
|
|
more likely to occur. You could enable
|
|
<a href="../../config/options/">ignorepponrename</a> however doing so would
|
|
contradict the intention of using a path restrictive policy.</p>
|
|
<h3 id="poorly-written-software">Poorly written software</h3>
|
|
<p>There are some pieces of software that do not properly handle <code>EXDEV</code>
|
|
errors which <code>rename</code> and <code>link</code> may return even though they are
|
|
perfectly valid situations and do not indicate actual device,
|
|
filesystem, or OS problems. The error will rarely be returned by
|
|
mergerfs if using a non-path preserving
|
|
<a href="../../config/functions_categories_policies/">policy</a> however there are
|
|
edge cases where it may (such as mounting another filesystem into the
|
|
mergerfs pool.) If you do not care about path preservation set the
|
|
mergerfs policy to the non-path preserving variant. For example: <code>-o
|
|
category.create=pfrd</code>. Ideally the offending software would be fixed
|
|
and it is recommended that if you run into this problem you contact
|
|
the software's author and request proper handling of <code>EXDEV</code> errors.</p>
