[OmniOS-discuss] l2arc 16.0E accounting leak

[wuffers]

I finally pulled the trigger on r151022, and am still experiencing this
after re-adding the cache devices. I had previously removed my l2arc in
r151020.

I see the bug documented here:
https://www.illumos.org/issues/5701 to https://www.illumos.org/issues/7410
https://www.illumos.org/issues/7867

Is anyone else still seeing this in r151022?

My cache devices are 400G each:

# zpool iostat -v
