Docker and GPFS


(Carlasau) #1

Hi all,

What storage driver would you recommand for using Docker on RHEL7.2 nodes with GPFS?
I have not chosen yet whether I was going for Docker EE or Docker CE.

I did not find help in the official Docker documentation nor in the compatibility matrix given for Docker EE. I just see that with RHEL I should use devicemapper, overlay2.
The only related thread I found relevant is from the IBM forum but it is quite old now. It recommends I guess to use VFS because it is POSIX file I/O.

Therefore I wanted to check whether any of you had some recent feedback on the subject, and what driver you noticed being the more adequate.

Thank you very much for your time!
Carla
