Subject Re: Bootstrap Timing
Date Mon, 21 Apr 2014 14:32:20 GMT
The new node has managed to stay up without dying for about 24 hours now...
but it still is in JOINING state. A new concern has popped up. Disk usage
is at 500GB on the new node. The three original nodes have about 40GB each.
Any ideas why this is happening?
