I don't believe that is the case. What I'm talking about is "growing an
array with devices". So you have 3 disks in a raid5/raidz array, and
then you add another disk, causing the free space on the array to grow
from (3-1) disks worth of space to (4-1) disks worth of space. Data is
preserved across this growth.
You might want to read up on ZFS. Then you'll believe it.
Linux can achieve the above with four commands.
Solaris can do it with 1 command, I believe.
What you have described is adding a disk to a zpool. I'm not sure what
your confusion might have been in regard to non-standard vocabulary.
Maybe I'm mis-understanding you.
