Greetings,
I've been slowly trying to debug a recent behavior change. Since
moving into the 4.9.90+ kernel tree, the udev link creation of
/dev/bcache/by-label and /dev/bcache/by-UUID has ceased to function. I
spent some time in udev channels looking for support and ultimately
routed me back to bcache for support. I don't agree with this but I'm
not familiar enough to engaged the udev team and speak fluently about
the bcache expectations. It looks like we're not using the 69-bcache
rules but insted only vdev creation. Can anyone assist me in
troubleshooting the lack of symlinks?
Thanks
