- Use Case Scenarios
s3fs is a FUSE filesystem that allows you to mount a S3 compatible bucket as a local filesystem. It stores files natively and transparently in S3 compatible Objective Storage (i.e., you can use other programs to access the same files). Maximum file size=64GB (as of this article, limited by s3fs, not Lumen Cloud Object Storage). The limitations of s3fs is listed here. For pricing of Object Storage, please see the pricing page.
Access to the Lumen Cloud platform as an authorized user
Identify a CentOS Linux platform that you would like to have s3fs installed

Access to Lumen Cloud Object Storage
Use Case Scenarios
As Object Storage is accessed using the Internet, it can be used in many scenarios. While mounting Object Storage as a Linux file system makes consuming Object Storage much easier, keep in mind that it is only accessed via the Internet, hence the speed and latency is not the same as local storage. With this in mind, using Object Storage in a file system can be a good alternative to expensive local storage. Use cases can be:
Arquivamento de dados
Internet speed data storage
Long term storage
If encryption is a requirement, please see s3QL, files created with S3QL can only be accessed using S3QL.
In preparation. There are several factors need to be considered:
Deployment of s3fs will install Git, gcc along with Make and Fuse (for full list of packages, please refer to s3fs GitHub site)
Mountpoint for the Object Storage filesystem
There are two methods to deploy s3fs in Lumen Cloud, it can be done manually or using a package.
s3fs deployment is done with the following commands on the CentOS 7 server:
sudo yum install automake fuse fuse-devel gcc-c++ git libcurl-devel libxml2-devel make openssl-devel git clone https://github.com/s3fs-fuse/s3fs-fuse.git cd s3fs-fuse ./autogen.sh ./configure make sudo make install
Once installed, access to the Object Storage screen in the Control Portal
Locate the user and bucket for this deployment and record both the "Access Key ID" and "Secret Access Key"
Create a password file with the "Access Key ID" and "Secret Access Key" and make proper permission on the file, for example:
echo access_key_id:secret_access_key > /path_to_password_file/password_s3fs chmod 666 /path_to_password_file/password_s3fs
Once the above steps are completed, create a directory for the mount point of the new filesystem
Execute using a package
A script (S3fs on CentOS 7) is created to speed up the deployment of s3fs on Lumen Cloud. The detail of the package is available here. The package can be install via the portal, API or CLI.
For API, please refer to the Execute Package API.
The CLI deployment can be done following the command in the Lumen Cloud Guide to CLI.
When using the portal, this Knowledge article
In the portal, the package can be found by searching for s3fs:
The parameters required for this script are:
Test the installation with the command below. For the current list of Object Storage end points, please see this knowledge article:
s3fs mybucket:/ /path_to_mountpoint -o passwd_file=/path_to_password_file/password_s3fs -o url=https://canada.os.ctl.io/
If the command ran successfully, then a /etc/fstab entry can be inserted to mount the Object Storage bucket permanently, a fstab_entry file is created in the /root directory if the package is used (debug level set at info, it can be removed to minimized logging):
s3fs#mybucket:/ /path_to_mountpoint fuse _netdev,dbglevel=info,allow_other,nodnscache,retries=5,url=https://canada.os.ctl.io/,passwd_file=/path_to_password_file/password_s3fs
mybucket:/ /path_to_mountpoint fuse.s3fs _netdev,dbglevel=info,allow_other,nodnscache,retries=5,url=https://canada.os.ctl.io/,passwd_file=/path_to_password_file/password_s3fs
Debug and run s3fs in the foreground can help during troubleshooting (-d x 2 to direct messages to STDOUT):
s3fs mybucket:/ /path_to_mountpoint -o passwd_file=/path_to_password_file/password -o url=https://canada.os.ctl.io/ -d -d -f -o f2 -o curldbg
