Issue

  • Changed default IO queue count to 15 with queue depth of 128.

::*> nvme subsystem modify -vserver vs1 -subsystem nvme -default-io-queue-count 15 -default-io-queue-depth 128

::*> nvme subsystem show -fie default-io-queue-count
  (vserver nvme subsystem show)
vserver           subsystem default-io-queue-count
----------------- --------- ----------------------
vs1               nvme      15

::*> nvme subsystem show -fie default-io-queue-depth
  (vserver nvme subsystem show)
vserver           subsystem default-io-queue-depth
----------------- --------- ----------------------
vs1               nvme      128

  • The number of queue counts still returns to 2.

[root@nvme01.extncl ~]# nvme get-feature /dev/nvme0n10p1 --feature-id 7 --human-readable
get-feature:0x7 (Number of Queues), Current value:0x010001
        Number of IO Completion Queues Allocated (NCQA): 2
        Number of IO Submission Queues Allocated (NSQA): 2
