But there seems to be contradictory information elsewhere. Docker themselves, for their enterprise edition say Devicemapper must be used:
If you use Docker EE on RHEL, CentOS, or Oracle Linux, you must use the devicemapper storage driver.
And this comment on SO says not to use Aufs:
You don’t. (And you don’t want to use aufs.) Just use devicemapper. But set it up for real instead of these testing-grade loopback files. – Michael Hampton
I haven’t changed anything with docker or anything else on the server - is there any reason why this warning is appearing now?
- Should I change to Aufs?
- Will it affect the rest of the server? (There are other sites including non-docker ones on the server).
- Or shall I proceed with devicemapper?
