The cluster is actually in recovery, so it take longer than usual, but
5 minutes to get an answer is really a long time.
Node info is not much different.
What I'm considering is that, with a bigger cluster (10 - 20 nodes)
this time may became really huge.

Do you know the reason of such big time?

'df -h' is instantaneous.
'du -sh' is not!

May it be possible/clever to retrieve the info from df ?
