Subject: [PATCH] imsm: fix: thunderdome may drop 2tb attribute

Spare superblock doesn't depend on other spares in container.
When loading container metadata thunderdome
may pick a small disk for the champion. This will result in incorrect
interpretation of sizes of other disks in container when joint
superblock
is returned. If any disk in container has the 2TB attribute set, the
result
must have it set too.
