No good. It happened again and the only thing showing up in lsof
that's even remotely a match is the kernel process associated with the
filesystem instance. "[xfs-data/sde103]". The mountpoint has been
removed by the automatic mounting facility (udev? systemd?). The
device is no longer id /dev (udev?). There's nothing useful in the
output of "find /proc -ls" either.

Any other suggestions to locate the processes that are holding up XFS?
