I do now.
I'm quite surprised though.  Any attempted by other programs to access the
devices should cause the resync to slow down the the "min" value which is
really quite slow.
So my guess is that something is going wrong with the detection of "other
programs accessing the device".

Can you tell me a bit about the configuration of your storage - what devices,
what connections, and LVM in use, what raid levels, partitions, etc.
