Hi Mike, I'm trying to test NVMeoF multi-path. root@host:~# lsmod |grep dm_multipath dm_multipath 24576 0 root@host:~# ps aux |grep multipath root 13183 0.0 0.1 238452 4972 ? SLl 13:41 0:00 /sbin/multipathd I have nvme0 and nvme1 that are 2 paths to the same NVMe subsystem. root@host:/sys/class/nvme# grep . nvme*/address nvme0/address:traddr=192.168.3.2,trsvcid=1023 nvme1/address:traddr=192.168.2.2,trsvcid=1023 root@host:/sys/class/nvme# grep . nvme*/subsysnqn nvme0/subsysnqn:nqn.testiqn nvme1/subsysnqn:nqn.testiqn root@host:~# /lib/udev/scsi_id --export --whitelisted -d /dev/nvme1n1 ID_SCSI=1 ID_VENDOR=NVMe ID_VENDOR_ENC=NVMe\x20\x20\x20\x20 ID_MODEL=Linux ID_MODEL_ENC=Linux ID_REVISION=0-rc ID_TYPE=disk ID_SERIAL=SNVMe_Linux ID_SERIAL_SHORT= ID_SCSI_SERIAL=1122334455667788 root@host:~# /lib/udev/scsi_id --export --whitelisted -d /dev/nvme0n1 ID_SCSI=1 ID_VENDOR=NVMe ID_VENDOR_ENC=NVMe\x20\x20\x20\x20 ID_MODEL=Linux ID_MODEL_ENC=Linux ID_REVISION=0-rc ID_TYPE=disk ID_SERIAL=SNVMe_Linux ID_SERIAL_SHORT= ID_SCSI_SERIAL=1122334455667788 But seems multipathd didn't recognize these 2 devices. What else I'm missing? Thanks, Ming -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
