I have docker container running on CentOS 7. I need to copy some files to the container, but when I use the docker cp command, I get the following error -
$ docker cp server.properties ctr_kafka:/opt/kafka_2.10-0.10.0.1/config/server.properties
Error response from daemon: no space left on device
The journalctl has the following message -
May 15 13:48:58 localhost dockerd[9902]: time=“2019-05-15T13:48:58.414938284Z” level=error msg=“Handler for HEAD /v1.39/containers/ctr_kafka/archive returned error: no space left on device”
May 15 13:48:59 localhost dockerd[9902]: time=“2019-05-15T13:48:59.707464989Z” level=error msg=“Handler for PUT /v1.39/containers/ctr_kafka/archive returned error: no space left on device”
I have verified that there is enough free disk space available [34% is in use, rest is free, more than 18GB]. The inodes are also free.
