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 --=20 ___ =20 ( ' } | Robin Hill | / / ) | Little Jim says .... | // !! | "He fallen in de water !!" | --azLHFNyN32YCQGCU Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (GNU/Linux) iEYEARECAAYFAksfwnoACgkQShxCyD40xBJyowCfbiAeg1hhGATNm96WtN8fwZNO ljEAnj4LljZ1EtaEz5f8+KembkWJfHy9 =NbHw -----END PGP SIGNATURE----- --azLHFNyN32YCQGCU--
