Hi.
I have two questions about MD..
1) I've written a udev rule to remap /dev/sdX devices on my system to
/dev/cXeYsZpA (controller, enclosure, slot, partition) mapping. When I
reboot the system, I see that all the devices in /dev are appropriately
renamed. If I look at /proc/mdstat, it still has the kernel names of
the devices (/dev/sdX) even though those devices no longer exist. If I
do an mdadm --detail /dev/mdX the system reports the proper device name
makeup. I manually failed a device, and I got the correct device name
in the email. I'm just wondering what command I would execute to make
/proc/mdstat update the devices in its output?
2) Unrelated to 1) -- the argument re: using MD on full devices versus
partitions has been around for a long time. I've been experimenting
with using it on full devices. One of the arguments that I've read for
not using full devices is that apparently, if you have two devices that
are identical, but one of them is slightly smaller than the other due to
say, bad sectors, then these disks can't be used together in one MD
because they are different sizes. I'm wondering how valid that argument
is? Surely it would make sense if MD was using full devices for it to
actually stop short of the end of the disk for situations like these...
Thanks for any help you can provide.
Jason.
