SubjectReconfiguring one SW-RAID when other RAIDs are running
Hi all,

I'm trying to re-create a RAID while leaving the other RAIDs --
including the root filesystem -- running, but mkraid refuses to run:

hera 1 # mkraid /dev/md2
/dev/md0: array is active -- run raidstop first.
mkraid: aborted.
(In addition to the above messages, see the syslog and /proc/mdstat as well
for potential clues.)

hera 2 # cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid5] [multipath]
read_ahead 1024 sectors
md1 : active raid5 sdf2[5] sdc2[4] sde2[2] sdd2[3] sdb2[1] sda2[0]
50339328 blocks level 5, 64k chunk, algorithm 0 [4/4] [UUUU]

md0 : active raid5 sdf3[5] sdc3[4] sde3[2] sdd3[3] sdb3[1] sda3[0]
298881024 blocks level 5, 64k chunk, algorithm 0 [4/4] [UUUU]

unused devices: <none>


(And no, there is no overlap between them.)

Anyone know how to work around this problem? This is using
raidtools-1.00.2-1.3 from RedHat, which seems to be just
raidtools-1.00.2.tar.gz.

(Also note: the raid directory on kernel.org seems to be abandoned.
Unless someone speaks up I'm going to remove it.)
