mdadm lies on RHEL 2.1?

In RHEL 2.1, /proc/mdstat is not consistent.



/proc/mdstat shows failure:

[root@linux01 root]# grep F /proc/mdstat

md3 : active multipath sdd[1] sdi[0](F)

md1 : active multipath sdb[1] sdg[0](F)

sdi and sdg are marked as failures.

When queried with mdadm, both paths appear to be online. So, who's lying here? Mostly /proc/mdstat, as I could dd in from the paths:

[root@linux01 root]# mdadm -D /dev/md3
