hello
I have troubles to get multipathing working on gentoo. I have an identical
setup working on a debian box.
The problem is that LVM does not detect labels on the multipath device
node; instead it does try to use a physical path (eg /dev/sda1)
the device nodes /dev/dm-X are not automaticaly created like they get on
debian, I did run dmsetup mknodes which did not create /dev/dm-X nodes, so
i created /dev/dm-0 with the minor/major of the corresponding /dev/mapper/
node. I don't know if this is a problem.
anyway, I've pasted alot of output to http://pastebin.com/wheL4nyE
change the preferred_names in /etc/lvm.conf to reference /dev/mapper
entries before /dev/sd
eg:
preferred_names = [ "^/dev/mapper/" ]
