[Gluster-users] GlusterFS over S3FS

[Vincent Miszczak]

Hello,


I would like to combine Glusterfs with S3FS.

The idea is to create a tiered volume composed of local network storage and remote object storage (something similar to vendor tiering solutions, but with some tiers being remote).


I have successfully setup local Glusterfs part on one side, and S3FS mount on another side:

-local volume is OK (create, start)

-creating a Gluster volume on S3FS is OK

-starting the volume on S3FS fails


(/gluster/s3fs is symlinked to /s3fs)

root at dfs:/gluster/s3fs# gluster volume create dfs dfs:/s3fs/test
volume create: dfs: success: please start the volume to access data
root at dfs:/gluster/s3fs# gluster volume start dfs
volume start: dfs: failed: Commit failed on localhost. Please check log file for details.


>From the log:

It looks like S3FS is not compliant with Gluster expectation.


Questions :

Has someone tried to do similar things ?

Is there any chance this kind of scenario can work ?


I also have the idea to test this with Swift object storage. Advises are welcome.


Vincent
