comment Cassandra on Linode: Dark magic isn't working
Update here in case anybody from after 2011 shows up: this is not the case anymore. Linode runs on SSD as of mid-2014 and Amazon's EBS is not recommended by Datastax because EBS has to contend with network and is unpredictable (read more here: docs.datastax.com/en/cassandra/2.1/cassandra/planning/…). Ephemeral SSD is the recommended approach now on AWS.

comment How to resolve a stuck major compaction in Apache Cassandra?
I'm having this same problem on a small dev cluster running DSE 4.6 (C* 2.0.11.83). "nodetool stop compaction" does nothing. CPU is maxed out on both nodes. Heap is not even half utilized. I've taken threaddumps and everything seems normal.

comment cassandra nodetool repair - how to schedule properly?
In the last line of your answer, should that say "RF=2 is a recipe for disaster..." as indicated by OP's RF? I've personally been burned by by setting RF=2 and QUORUM CL.

comment DFS File Storage and XenServer VMs on iSCSI Target with Two, Cross-Country locations
Thanks for the great answer! I will remember this for my AD. I believe DFSR in server 2008 supports asynchronous I/Os; thanks for alerting me to the potential issue there. The snaps may be a bigger issue, but I'm really only relying on them for true disaster.

comment Deny Static IP Assignments
Thanks for the answer, Tom. I figured I was just missing something in my understanding here. I'm looking to get new hardware soon, but I'll see if my current switch supports this.

Thanks for the great response. Although my switch is not currently Cisco, I am actually looking to acquire new hardware soon and this advice will help in any case.
