From mboxrd@z Thu Jan 1 00:00:00 1970 From: Justin Maggard Subject: [PATCH] Create new md devices consistently Date: Tue, 23 Oct 2012 15:04:00 -0700 Message-ID: <1351029840-5030-1-git-send-email-jmaggard10@gmail.com> Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org Cc: Justin Maggard List-Id: linux-raid.ids Creating a new MD device with the name 'd-0' results in some unexpected behavior, since mdadm sees that '-0' is a non-negative integer and therefore makes a "partitionable" device (/dev/md_d0). This is not the expected behavior, since the documentation mentions 'dN' several places, and a reboot brings it up as /dev/md/d-0. Make this consistent by ensuring that the character immediately following 'd' is a digit during creation. --- mdopen.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/mdopen.c b/mdopen.c index 61eda81..24188df 100644 --- a/mdopen.c +++ b/mdopen.c @@ -207,7 +207,10 @@ int create_mddev(char *dev, char *name, int autof, int trustworthy, char *ep; if (cname[0] == 'd') sp++; - num = strtoul(sp, &ep, 10); + if (isdigit(sp[0])) + num = strtoul(sp, &ep, 10); + else + ep = sp; if (ep == sp || *ep || num < 0) num = -1; else if (cname[0] == 'd') -- 1.7.9.5
