software raid in AIX is handled by the LVM layer, and if the LV is
configured for mirroring ('copies=2'), then the resized LV will also be
mirrored.
does lvresize resize the file system while online? I didn't think it
did. the man page for fsadm (referenced in the lvresize man page) says
ext2/3/4 is unmounted before resizing. ooops. kind of hard to umount
/var !
