重启 EC2 实例后 AWS S3 存储桶未重新挂载

Question

I mounted my S3 bucket to my EC2 Instance using S3fs , and I was able to read, write to my S3 bucket. But after restarting my EC2 Instance, S3 bucket is automatically unmounted. I found that to make it persistent and automatically mount for every reboot we need to add below entries to /etc/rc.local

/usr/bin/s3fs myS3bucket -o use_cache=/tmp -o allow_other -o multireq_max=5 /myS3bucket

But still It is not mounting on reboot.

Answer 1

Did you went through the official documentation ?

You can also mount on boot by entering the following line to /etc/fstab:

s3fs#mybucket /path/to/mountpoint fuse _netdev,allow_other 0 0

or

(…)

Note2: You may also need to make sure netfs service is start on boot

A network mount requires a network access in the first place.

Answer 2

I was able to make it work by running it as systemd service.

• Create Service File - /usr/lib/systemd/system/mybucket-mount.service
