Hi All,
I am working on NVMe over fabric and want to experiment the Multipathing support for the same.
Setup Info:
RHEL 7.2 with Kernel 4.9.3
[root@localhost ~]# nvme list
Node SN Model Namespace Usage Format FW Rev
---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- --------
/dev/nvme0n1 30501b622ed15184 Linux 10 268.44 GB / 268.44 GB 512 B + 0 B 4.9.3
/dev/nvme1n1 ef730272d9be107c Linux 10 268.44 GB / 268.44 GB 512 B + 0 B 4.9.3
[root@localhost ~]# ps ax | grep multipath
1272 ? SLl 0:00 /sbin/multipathd
I have connected my Initiator to both the ports of Ethernet Adapter(Target) to get 2 IO Paths, from the above data "/dev/nvme0n1" is path 1 and "/dev/nvme1n1" is path 2 for the same namespace.
Note: I am using Null Block device on the Target Side.
But still the multipath is showing an error ie no path to Host for All the NVMe Drives mapped on the Initiator. Does multipathd supports NVMe over Fabric ??
Or what I am missing from configuration side ??
Thanks in advance!!
