active bitmap rearrangement

[FLAPHEAD_COM]

So I am running Exchange JetStress on my Storage System and I am supposed to run:

priv set advanced

wafl scan status

and monitor for it all to be clear.  It has been two days now where I see a shed load of volumes all with "active bitmap rearrangement"

It doesnt seems to going anywhere fast..  Anyone got any idea how long this is going to take?

Also if I run

priv set diag

aggr scrub status -v

I see a number of aggr with:

aggr scrub: status of /aggr01_sata/plex0/rg0 :

        Current scrub is 25% complete (suspended).

        First full scrub not yet completed.

Any thoughts?

Those active bitmap rearrangement scans are always present and perfectly normal.

They are background block reallocation scans that are constantly running on every writable online volume. See this KB for more info on "wafl scan status" output:
