Re: Adding nodes

Having a node UJ but not sending/receiving other streams is an invalid state (unless 4.0 moved the streaming data out of netstats? I'm not 100% sure, but I'm 99% sure it should be there). It likely stopped the bootstrap process long ago with an error (which you may not have seen), and is running w

Re: Adding nodes

From the nodetool output you quoted, I seriously suspect your Cassandra nodes have at least one of the following issues: * Clock out of sync * Bad network connectivity between nodes * Long GC pauses * Broken disks * CPU bottleneck It's not normal to see over 2% dropped small

RE: Adding nodes

Ifconfig shows RX of 1.1T. This doesn't seem to fit with the LOAD of 145GiB (nodetool status), unless I am reading that wrong...and the fact that this node still has a status of UJ. Netstats on this node shows (other than : Read Repair Statistics: Attempted: 0 Mismatch (Blocking): 0 Mismatch (Ba

Re: Adding nodes

I would assume that's 85 GB (i.e. gigabytes) then. Which is approximately 79 GiB (i.e. gibibytes). This still sounds awfully slow - less than 1MB/s over a full day (24 hours). You said CPU and network aren't the bottleneck. Have you checked the disk IO? Also, be mindful with CPU usage. It can
