Hello
I'm trying to setup a FC Storage (Adaptec SANBloc 2Gb) using multipath
(Kernel 2.6.15 - multipath-tool-0.4.7 on Fedora Core 5 )
Everything seem to run right, but the disk created by multipath does not
reflect the physical one.
I do have a physical volume that is about 67GB big, when multipath
creates the dm device it is at least 1GB.
Here is the output of multipath -v3:

----------------------------------------------------
When you look at the disk size, it return the correct value but when it
creates the dm device it does it too small.
Do you have any Idea why this happen?
Thanks a lot for your work and your help

Arsène
