Automatically mount bucket with s3fs on boot

Question

I use an Amazon S3 bucket to deliver some of my server's content. I was able to mount it successfully, and grant Apache rights over it, but can't get it mounted properly at reboot.

I updated my /etc/fstab with this line, but nothing happens when I boot

s3fs#my-bucket-name /mnt/s3_bucket fuse allow_other,umask=227,uid=33,gid=33,use_cache=/root/cache 0 0

So, I tried another way, commented said line, and just put my command line in /etc/init.d/local :

#!/usr/bin/env bash
s3fs -o allow_other,uid=33,gid=33,umask=227,use_cache=/root/cache my-bucket-name /mnt/s3_bucket

... didn't work either.

I ended up putting a cron, and now, it works, but it feels terribly hacky to me, and I wonder why mounting it at start doesn't work.

//Crontab
*/10 * * * * ~/mountBucket.sh 1>/dev/null

//Mount script
#!/usr/bin/env bash
if [[ -d /mnt/s3_bucket/someBucketVirtualDirectoryName ]] ; then echo 'Bucket already mounted' ; else s3fs -o allow_other,uid=33,gid=33,umask=227,use_cache=/root/cache my-bucket-name /mnt/s3_bucket ; fi 1>/dev/null

Is there something I missed ?
I'm Using Ubuntu 14.04.4 LTS, with Fuse 2.9.2

EDIT : Here is another unrelated, yet important performance issue I had to figure out by myself:

If your system includes locate and/or mlocate (and Ubuntu 14.04 does), you may want to add an exception, so that it does NOT scan your bucket. I had to modify both my /etc/updatedb.conf and /etc/cron.daily/locate, adding " /mnt/my-bucket-name" to PRUNEPATHS and " fuse.s3fs" to PRUNEFS I suppose adding fuse.s3fs should be enough, but... no time to take risks right now :)

Solution

You want to add _netdev to your fstab:

s3fs#my-bucket-name /mnt/s3_bucket fuse _netdev,allow_other,umask=227,uid=33,gid=33,use_cache=/root/cache 0 0

Looks like it's as simple as this. Too bad this option was hardly ever mentioned, and nowhere explained in any of the tutorials or articles I found, while it seems absolutely necessary. Big thanks.

it's actually in s3fs's README github.com/s3fs-fuse/s3fs-fuse

I noticed it after, but it's not explained on that page. There's one answer about it in the FAQ, which is quite clear, but I'm not used to Github enough to know pages include a FAQ. Half of the other blog/tutorial/forums pages I browsed didn't include the _netdev option when showing a fstab line, and for the other half, it's here among other stuff, but without explaination (while allow_other is often higlighted). Therefore, I had no idea of how important it could be. IMO, simple questions like this should be answered on SE anyway. Immediate google answers to basics helps going further
