Hence WildFly is of limited functionality when the more and more popular overlayfs storage driver is used, and the WildFly team might be interested in providing a workaround on their side since there is no indication the OpenJDK bug will be promptly fixed. However everything seems to run fine in WildFly except once the backup of the config is triggered, for example by using the cli. > We acknowledge that this is in fact an OpenJDK AND/OR overlayfs bug. > at .LinuxFileStore.findMountEntry(LinuxFileStore.java:91) > java.io.IOException: Mount point not foundImage > inside a Docker container running on overlayfs as storage driver > /opt/jboss/bin/jboss-cli.sh -file=/opt/jboss/jboss-config.cli > Mount point not found exception raised by createTempFileWithAttributes on overlayfs, i.e., > overlay2 (e.g., Docker for Mac): problem > overlay (e.g., CoreOS, current minikube): problem > aufs: works (e.g., boot2docker, legacy minikube) The overlay2 driver is only compatible with Linux kernel 4.0 and later. Since version 1.12, Docker also provides overlay2 storage driver which is much more efficient than overlay in terms of inode utilization. > on Docker with overlayfs or overlayfs2 as storage driver Docker’s overlay storage driver leverages several OverlayFS features to build and manage the on-disk structures of images and containers. > Environment: WildFly via Ke圜loak 2.5.1.Final > Mount point not found exception raised by createTempFileWithAttributes on overlayfs We still haven't released WildFly Core 3, so this is good feedback.
