Why do you guess this? The manual page should tell you exactly what's
supported, and even mdadm 3.1.1 makes no mention of support for growing
linear RAID:
Currently supported growth options including changing the active
size of component devices and changing the number of active
devices in RAID levels 1/4/5/6, changing the RAID level between
1, 5, and 6, changing the chunk size and layout for RAID5 and
RAID5, as well as adding or removing a write-intent bitmap
Cheers,
Robin
