Hi, I have the following nullfs mount: /data/downloads on /usr/jails/dlna/mnt/data (nullfs, local, read-only) For some reason, the mount command output shows this: zroot/virtuals/bhyve/fbsd3 at change-volmode/data/downloads on /usr/jails/dlna/mnt/data (nullfs, local, read-only) This happened for all nullfs mounts, not just this one. It appeared yesterday, after 40 days of uptime. Before that the mount was shown properly. This extra prefix is probably from the zfs volume that I'd created just before the issue started appearing: zroot/virtuals/bhyve/fbsd3 The zfs volume is not related to /data/downloads mountpoint. I haven't rebooted the system since, does anyone know how to debug this?
