http://bugzilla.opensuse.org/show_bug.cgi?id=1181605 Bug ID: 1181605 Summary: Kernel BTRFS assertion failed when creating a docker container Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: thdiaman@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 845658 --> http://bugzilla.opensuse.org/attachment.cgi?id=845658&action=edit kernel log greetings everyone, not sure if this is docker related, btrfs/kernel related or DB2 related (or all of them) but here we go :) when trying to start a (specific) container (namely https://hub.docker.com/r/ibmcom/db2) with a BTRFS attached volume (either named volume or an external mount point) i get a kernel error about a failed assertion in system log and the container hangs. i can kill the container but then i have to reboot otherwise any operation on that folder will fail miserably (process is zomb-ied, reset button is the only way to restart). the same docker run command if executed with an ext4 volume, is just fine. Reproducible: always. also reproducible since at least a couple of kernel (minor) versions back. - openSUSE Tumbleweed / 5.10.9-1-default kernel - btrfs-progs v5.9 - docker version: Client: Version: 19.03.14 API version: 1.40 Go version: go1.13.15 Git commit: 5eb3275d4006 Built: Wed Dec 23 00:00:00 2020 OS/Arch: linux/amd64 Experimental: false Server: Engine: Version: 19.03.14 API version: 1.40 (minimum version 1.12) Go version: go1.13.15 Git commit: 5eb3275d4006 Built: Wed Dec 23 00:00:00 2020 OS/Arch: linux/amd64 Experimental: false containerd: Version: v1.3.9 GitCommit: ea765aba0d05254012b0b9e595e995c09186427f runc: Version: 1.0.0-rc10 GitCommit: dc9208a3303feef5b3839f4323d9beb36df0a9dd docker-init: Version: 0.1.5_catatonit GitCommit: Docker command: docker run --name db2luw-with-luv --privileged=true -v data-db2luw:/database -p 50000:50000 -e LICENSE=accept -e DB2INST1_PASSWORD=12345678 -e DBNAME=testdb ibmcom/db2 Kernel log attached. -- You are receiving this mail because: You are the assignee for the bug.
