zdb doesn't show cache (l2arc) drives

[aufalien]

Hi all,

First off, my apology if this has been posted.

Upon doing a zdb, my cache drives don't show. All 40 data drives in the pool as well as my zil show, just not the l2arc.

Also, while I am experimenting only, I installed zfs-stats tool suite and it also doesn't have any ref to l2arc.

The GUI does show them however via;

Storage -> Volumes -> View Volumes - Volume Status

Any insight would be very cool.

I'm debugging a 10% reduction in IO in my lab and want to now if I should be concerned with zdb output.

Thanks in advance.

What does zpool status say?

Well my fine feathered friend, it does show up there so thank for that.

Funny, I use zpool iostat but should be in the habit in using it for other things.

I also see gstat showing those disks getting some I/O so I suppose this is a non issue perhaps. At any rate, many thanks for replying.
