John,
Thank you for suggestions:
I looked into journal SSDs. It is close to 3 years old showing 5.17% of
wear (352941GB Written to disk with 3.6 PB endurance specs over 5 years)
It could be that smart not telling all but that it what I see.

How do you look at cstates?

I'd take a look at cstates if it's only happening during periods of
low activity. If your journals are on SSD you should also check their
health. They may have exceeded their write endurance - high apply
latency is a tell tale sign of this and you'd see high iowait on those
disks.
