Proposed fix: [Sysbox] 'failed to setup docker volume manager: host dir for docker store /var/lib/sysbox/docker can't be on …' — /var/lib/sysbox must be ext4 or btrfs
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Put /var/lib/sysbox and /var/lib/docker on ext4 or btrfs (e.g. a dedicated disk/partition), then restart sysbox and Docker.
Option: Put /var/lib/sysbox and /var/lib/docker on ext4 or btrfs (e.g. a dedicated disk/partition), then restart sysbox and Docker. [evidence: official_recommended_action]
Applies when: Running Sysbox on hosts where /var/lib/sysbox (or /var/lib/docker) sits on overlayfs, xfs without ftype, tmpfs or network storage
Steps:
1. df -T /var/lib/sysbox /var/lib/docker
2. Move the directories to an ext4/btrfs volume (bind mount or symlink).
3. Restart sysbox and docker.
Expected: The error no longer appears.
