Subject: tests/10ddf-fail-stop-readd: New DDF unit test
X-Git-Tag: mdadm-3.3.1~108
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f502b11c743d9fb27615776d42c2daea4edb0f97;p=thirdparty%2Fmdadm.git

tests/10ddf-fail-stop-readd: New DDF unit test

This is similar to 10ddf-fail-readd. The difference is that the
array is stopped and incrementally assembled before the disk is
re-added.
