Subject: Grow: allow "--add" with "--grow --level=??"
X-Git-Tag: mdadm-3.3-rc1~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1c8b90df155c7eef46f56986eeef911b9744e70a;p=thirdparty%2Fmdadm.git

Grow: allow "--add" with "--grow --level=??"

This is useful for reshaping a RAID0 to a higher level.
The recovery will happen at the same time as the reshape.
