Description

During a scrub process on my 4.5TB pool, "General Status" shows over 300,000KB/s (300MB/s) of disk activity in reads, but "Disk Sets" shows zero's across the board?

See screenshots.

I believe this stats updates every minute, i.e. not 30 seconds. Did you wait long enough to see counters got updated? Also, I think its a bug anyways.. we just need to get your final confirmation that what I suspecting isn't a case.

Yes I watched it over a period of time and it never changed.

I'm experiencing a similar in 3.0 as well (also present in 2.2.0)

I'm currently on 3.0.0.1 (planning to upgrade to 3.0.2 this weekend), and the dials are frozen at a long passed activity level although the individual disk counters reflect current activity.

See attached screen captures.

Guys, can i please you restart NMS/NMV services and watch for the dials? Also i want to know - do you see the same issues with other dials (CPU, Network)?

My dials work fine (I've not seen them get stuck).. the problem is the disk activity under datasets does not reflect the disk activity in the general status page (on the dials)

Can you restart both services and check it again? Before the restart show me the output of "show collector volume-collector" command.

I found this bug looking for a solution to my dials being stuck. Before restarting NMS/NMV "show collector volume-collector" reports:

COLLECTOR               STATUS        STATE     DAEMON  SCHEDULE
volume-collector        enabled       ready     -       hourly

Restarting NMS and NMV did not unstick my dials. Still looking for a solution to this problem.
