>Description:
I made a RAID 5 set, created a 4.2BSD filesystem on it, and mounted the
filesystem.  Issuing "raidctl -s raid0" while the filesystem is mounted
results in "raidctl: unable to open device file: /dev/raid0d".  The
same command after unmounting the filesystem works as expected.  This
can't be right, since the point of hot spares and most RAID is to be
able to recover from a failed disk without incurring downtime for the
system or the applications.
>How-To-Repeat:
Make a RAID set, put a filesystem on it, mount the filesystem, and
try "raidctl -s" on the RAID device.
>Fix:
No idea.
