This also raises another point, which is relevant for both cases - same
exact models of hard disks have different number of cylinders, so if a
RAID partition is created on a larger drive it cannot be mirrored to a
smaller drive.
I have a RAID5 with 5 250G drives, but some are 251 GiB

No, but it is a very fast swap

You lose a bit of space, but if you ever need to change one, you won't

Not the same amount! Match the size of the NV RAM disk with RAM at a
fraction of the cost. With the money saved, buy a computer for the kids.

All right, this weekend I was able to use dd to create an imagefile
out of the disk.
I did the folowing:
dd conv=noerror if=dev/hdd1 of=/mnt/hdb1/Faulty-RAIDDisk.img
losetup /dev/loop0 /mnt/hdb1/Faulty-RAIDDisk.img
I edited the mdadm.conf, by replacing /dev/hdd1 for /dev/loop0.
But it did not

On HP-UX disk mirroring is done in LVM. I'm using md driver for
mirroring and LVM on top of it. Controlling access to my disks in LVM
is just too late. I would have to assemble the array before I can activate
VGs. If the array in question is being used on the other host nobody
can
I understand about HP-UX mirroring/LVM.
I was a little too obtuse.
LVM2 has a feature (not well advertised) that allows an VG to be tagged so it
will not be activated by system b if it is already tagged as being in use by
system a. I was suggesting that a similar feature could be added to MD.

May want to look at LVM2 and its ability to use tagging to control
enablement of VGs.

You must have missed my first posting, or maybe I was not clear enough.
We _are_ talking about the same thing.
Now we are already three or four thinking of it as a useful feature,
the pression on Neil is dramatically increasing ... ;-)
