I have this same -EEXIST problem. If the /dev/mapper/mpath* device node is mounted with a file sys when the disk is disconnected, multipath won't give up one of the device paths (logs "map in use"). If the disk is then reconnected it will get a new scsi device name. Now multipath is sometimes confused (shows 3 paths, one of which is ####), and sometimes I get the -EEXIST core dump to go along with it. I can do the same disconnect / reconnect of the disk all day long, as long as no file system is mounted on it. Of course, there will pretty much always be a file system mounted on it so that isn't really a solution, just a fact. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
