Hi. Due to a PEBCAK and wrong paths being removed I've now ended up
in this situation:
I readded the paths with 'echo - - - > /sys/class/scsi_host/host*/scan',
but the map does not get healthy - all attempts to reload the map with
the multipath tools ends up in blocking I/O, using dmsetup directly I
only get failures due to the map being busy.
