Hi, Sometimes when I stop a jail the filesystem is not unmounted.
/data/jails/freebsd14.1-RELEASE on /data/jails/jenkins/_root (nullfs, local, read-only, nfsv4acls, fsid 07ff002929000000, vnodes: count 1 ) [root@rpi4 ~]# umount 07ff002929000000 umount: unmount of /data/jails/jenkins/_root failed: Device busy Sometimes after some time the umount does succeed. How can I find what is keeping this mount busy? Ronald.
