How to register FUSE filesystem type with mount(8) and fstab?

I've written a small FUSE-based filesystem and now the only part's missing is that I want to register it with fstab(5) to auto-mount it on system startup and/or manually mount it with just mount /srv/virtual-db. How can I achieve this?

I know, I can just run /usr/bin/vdbfs.py /srv/virtual-db from some init script, but that's not exactly pretty.

I'm sorry because this may be not exactly a programming question, but it's highly related, as the packaging and deployment is still the programmer's job.

To clarify @patryk.beza comment on the accepted answer, the correct way to mount a FUSE file system is by setting the file system type to fuse.<subtype>.

For example, to mount an s3fs-fuse implementation, which does not provide a specific /sbin/mount.* wrapper and uses normally the s3fs user command to mount S3 buckets, one can use this command as root:

mount -t fuse.s3fs bucket-name /path/to/dir -o <some,options>

or this line in /etc/fstab:

bucket-name /path/to/dir fuse.s3fs <some,options> 0 0

or this SystemD mount unit (for example, /etc/systemd/system/path-to-dir.mount):

[Unit]
Description=S3 Storage
After=network.target

[Mount]
What=bucket-name
Where=/path/to/dir
Type=fuse.s3fs
Options=<some,options>

[Install]
WantedBy=multi-user.target

How this works: mount recognizes the concept of "filesystem subtypes" when the type is formatted with a period (i.e. <type>.<subtype>), so that a type with the format fuse.someimpl is recognized to be the responsibility of the FUSE mount helper /sbin/mount.fuse. The FUSE mount helper then resolves the someimpl part to the FUSE implementation, in the same way as the # format is used in the original answer (I think this is just a path search for a program named <subtype>, but I'm not 100% sure about it).

After researching a lot found this solution to mount fuse filesystem suing fstab entry. I was using fuse for s3bucket to mount on local linux machine.

  • .passwd-s3fs : Is containing credentials to access your aws account 1] Secret key and 2] Access Key .
  • uid : User Id. You can type linux command id and you can get uid

Syntax:

s3fs#<Bucket_Name> <Mounted_Direcotry_Path> fuse _netdev,allow_other,passwd_file=/home/ubuntu/.passwd-s3fs,use_cache=/tmp,umask=002,uid=<User_Id> 0 0

Example:

s3fs#myawsbucket /home/ubuntu/s3bucket/mys3bucket fuse _netdev,allow_other,passwd_file=/home/ubuntu/.passwd-s3fs,use_cache=/tmp,umask=002,uid=1000 0 0

To mount you need run following command.

mount -a

To check your bucket is mounted properly or not use following command to check which shows all mounted points.

df -h
