status

Overview

View the io_uring sqpoll mode status in the cache service of a virtual datastore

Command Parameters

-v|--volume-id=string      Required parameter, volume id, example: a4ef106e_vs_vol_rep2

Usage Example

acli storage asan io_uring sqpoll status -v a4ef106e_vs_vol_rep2

Output Example

sqpoll mode is enabled and all hosts in the volume are converged:

sqpoll-status   vol=a4ef106e_vs_vol_rep2                   STATUS: CONVERGED

  volume: desired=sqpoll  enabled=yes  hosts=3

  HOST               MODE    CONVERGED  KERNEL  SQD CPUS  NOTE
  host-002246213d6b  sqpoll  yes        6.6     70,72
  host-6c92bf51945a  sqpoll  yes        6.6     70,72

  DISKS
    4 disk(s) in sqpoll as expected

When the volume has never been configured or hosts are not converged, host status and disk details are expanded item by item:

sqpoll-status   vol=a4ef106e_vs_vol_rep2               STATUS: NOT CONVERGED

  volume: desired=<unset>  enabled=no  hosts=2   (never configured)

  host-6c92bf51945a  interrupt  yes        5.10    -

  DISKS
    1 disk(s) in interrupt as expected
