mdadm-3.2.6-3.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/mdadm-3.2.6-3.fc18
There is a typo done while porting this patch to mdadm-3.2.6-3.fc18: There is a line in the original patch (http://git.neil.brown.name/git?p=mdadm.git;a=commitdiff;h=066e92f017df22c879c455494d2c1743ef7f3aca): + pr_err("no free space left on %s\n", dname); It was ported to mdadm-3.2.6-3.fc18 as (in Create.c:411): + fprintf(stderr, Name "no free space left on %s\n", dname); It is wrong. The correct one should be (in Create.c:411): + fprintf(stderr, Name ": no free space left on %s\n", dname); Because now the message is following: mdadmno free space left on /dev/sda and the correct one should be: mdadm: no free space left on /dev/sda Could you correct that?
