### mount options

* **defaults**: a shortcut for FUSE's **atomic_o_trunc**, **auto_cache**, **big_writes**, **default_permissions**, **splice_move**, **splice_read**, and **splice_write**. These options seem to provide the best performance.
|
||||
* **direct_io**: causes FUSE to bypass caching which can increase write speeds at the detriment of reads. Note that not enabling `direct_io` will cause double caching of files and therefore less memory for caching generally. However, `mmap` does not work when `direct_io` is enabled.

The srcmounts (source mounts) argument is a colon (':') delimited list of paths to be included in the pool. It does not matter if the paths are on the same or different drives nor does it matter the filesystem. Used and available space will not be duplicated for paths on the same device and any features which aren't supported by the underlying filesystem (such as file attributes or extended attributes) will return the appropriate errors.

Please reread the sections above about policies, path preserving, and

the \f[B]moveonenospc\f[] option.

First make sure you\[aq]ve read the sections above about policies, path

Remember that mergerfs is simply presenting a logical merging of the

contents of the pooled drives.

The reported free space is the aggregate space available \f[I]not\f[]

The reported free space is the aggregate space available \f[B]not\f[]

MergerFS does not split files across drives.

If the writing of a file fills a drive and \f[B]moveonenospc\f[] is
|

disabled it will return an ENOSPC error.

|

If \f[B]moveonenospc\f[] is enabled but there exists no drives with
|
||||
enough space for the file and the data to be written (or the drive
|
||||
happened to fill up as the file was being moved) it will error
|

indicating there isn\[aq]t enough space.

|

It is also possible that the filesystem selected has run out of inodes.
|
||||
Use \f[C]df\ \-i\f[] to list the total and available inodes per
|
||||
filesystem.
|
||||
In the future it might be worth considering the number of inodes
|
||||
available when making placement decisions in order to minimize this
|

situation.
