FUSE Mount Options

This page summarizes common FUSE mount options used with JuiceFS Cloud Service. For complete explanations and deeper behavior notes, see the Community Edition guide: FUSE Mount Options.

How to pass FUSE options

You can pass FUSE options in two common ways:

1. Use -o in juicefs mount, with options separated by commas.

   juicefs mount -d -o allow_other,writeback_cache <META-URL> /jfs

2. In /etc/fstab, add FUSE options in the options field.

   # <file system>  <mount point>  <type>   <options>                    <dump> <pass>
   redis://localhost:6379/1  /jfs  juicefs  _netdev,writeback_cache      0      0

Common options (summary)

default_permissions

Enabled automatically. Kernel-side permission checks and file-system checks both need to pass.

allow_other

Allows access from users other than the mounter. For non-root mounts, enable user_allow_other in /etc/fuse.conf first.

writeback_cache

Enables FUSE writeback cache and can improve frequent small writes. Requires Linux kernel 3.15 or later.

user_id and group_id

Specify file-system owner UID/GID for permission validation. This does not take effect when allow_other is enabled.

debug

Prints low-level go-fuse debug logs to juicefs.log. This is different from the global client --debug option.
