I messed up the patch a bit. Apparently dm_get_uuid() can return a zero without actually having found a dm name which matches the name parameter. Also, I changed dm_get_uuid() so it either returns 1 or a null string in the uuid return parameter -- in 2 different cases it was doing neither. The <dm_device_name> qualifier for the command line "multipath -ll <dm device name>" can now accept up to 3 different names for the same dm mapped device, that is, a user friendly name, an alias in /etc/multipath.conf, and the current name as reported by "dmsetup ls". Is this OK or should we enforce that only the current name as reported by "dmsetup ls" is acceptable if the mapped device already exists? > -----Original Message----- > From: Christophe Varoqui [mailto:christophe.varoqui@xxxxxxx] > Sent: Monday, November 13, 2006 6:00 PM > To: goggin, edward > Cc: dm-devel@xxxxxxxxxx; dave.wysochanski@xxxxxxxxxx > Subject: Re: patch to get_refwwid() > inmultipath-tools/libmultipath/configure.c > > Le lundi 13 novembre 2006 à 17:32 -0500, Edward Goggin a écrit : > > Christophe, > > > > This patch enables "multipath -l <dm device name>" > > to work if the current dm_alias has been changed by > > "dmsetup rename" or other means. > > > Nice to have.
