hi all

$ vol heal $_vol info
outputs ok and exit code is 0
But if I want to see statistics:
$ gluster vol heal $_vol statistics
Gathering crawl statistics on volume GROUP-WORK has been 
unsuccessful on bricks that are down. Please check if all 
brick processes are running.

I suspect - gluster inability to cope with a situation where 
one peer(which is not even a brick for a single vol on the 
cluster!) is inaccessible to the rest of cluster.
I have not played with any other variations of this case, 
eg. more than one peer goes down, etc.
But I hope someone could try to replicate this simple test case.

Cluster and vols, when something like this happens, seem 
accessible and as such "all" works, except when you want 
more details.
This also fails:
$ gluster vol status $_vol detail
Error : Request timed out

My gluster(3.10.5-1.el7.x86_64) exhibits these symptoms 
every time one(at least) peers goes out of the rest reach.

maybe @devel can comment?

many thanks, L.
