I'm running into this on an AWS r5d.2xlarge instance. I create the instance with a 2TB EBS volume and am trying to setup its 300GB ephemeral SSD as a cache for the EBS volume.
This part works, (nvme2n1 is the SSD): make-bcache -C /dev/nvme2n1 --discard But, when I run this: make-bcache -B /dev/nvme1n1 I see the log messages: Jun 02 23:41:27 ip-10-26-8-43 multipath[8745]: nvme1n1: failed to get udev uid: Invalid argument Jun 02 23:41:27 ip-10-26-8-43 multipath[8745]: nvme1n1: uid = nvme.1d0f-766f6c3062623536336362353965333737383764-416d617a6f6e20456c617374696320426c6f636b2053746f7265-00000001 (sysfs) Jun 02 23:41:28 ip-10-26-8-43 systemd-udevd[8744]: nvme1n1: Process 'bcache-register /dev/nvme1n1' failed with exit code 1.
