Multinode docker based installation error


Re: Multinode docker based installation error

Rising Star
Hey Damion,

This volume size isn't baked into our image. If you're using Docker on
CentOS, you're likely defaulting to using devicemapper as your storage
driver, which is what imposed the free space limit you're seeing. My
recommendation would be to either move to an AWS instance running Ubuntu
and aufs as the driver, or Google around to learn how to change the
devicemapper sizes.


Re: Multinode docker based installation error


Ahhhh, that's why you get paid the BIG $$$$$$ ;-)


I am running devicemapper (as per info below).


So I guess I can convert to "thin-pool" and direct-lvm using steps under heading "Configure direct-lvm mode for production" here:
