They should be expected, since you can't read the passive link, but it's only failing on sector 0 which sounds like udev is trying to read the partition table. I think I remember fixing this behavior on a test box (that's long gone, now, so I can't look it up) by fiddling with the udev rules to not bother scanning the multipathed (i.e. fiber channel) devices. Sorry for the lack of specifics, but it's been a while, and I wasn't very specific in my own notes about what I did. They should be preventable, though, if I remember right. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
