Re: very slow repair
Hi, Thank you for your reply, Well, actually by running cfstats I can see that the totaldiskspaceused is about ~ 1.2 TB per node in the DC1 and ~ 1 TB per node in DC2. DC2 was off for a while thats why there is a difference in space. I am using Cassandra 3.0.6 and my stream_throughput_outbound_megabits_per_sec is th4e default setting so according to my version is (200 Mbps or 25 MB/s) Cheers ‐‐‐ Original Message ‐‐‐ On Thursday, June 13, 2019 6:04 AM, Laxmikant Upadhyay wrote: > Few queries: > 1.

very slow repair
Hi, I am trying to run a repair for first time a specific column family in specific keyspace and it seems that is going super slow. I have 6 nodes cluster with 2 Datacenters (RF 2) and the repair is a non incremental, DC parallel one. This column family is around 4 TB and it is written heavily (compared with other CF) so since it is going to take 2 months (according ETA in Reaper) does that mean that when this repair will finish the entropy will be again high in this CF ? How I can speed up the process ? Is there any way to diagnose bottlenecs? Thank you, W
Re: Moving a node to another RAC in the same DC.
Hi Laxmikant, My remaining nodes are using 60% of the HD.

Moving a node to another RAC in the same DC.
Hi, I have accidentally bootstrapped a node in a wrong RAC (RAC11) and I would like to move it to the correct RAC with the remaining nodes (RAC1). The status now is x.x.x.x=DC1:RAC1 x.x.x.x=DC1:RAC1 x.x.x.x=DC1:RAC1 x.x.x.x=DC1:RAC11 Due to issues with free storage I think will be dangerous to decommission and bootstrap back the node to RAC1. So my question is: Can I move directly the last node to RAC1? My settings: Cassandra v3.0.9 2 DCs (4/3 nodes respectively) (RF=2) endpoint_snitch: PropertyFileSnitch vnodes setup: num_tokens: 265 Thank you, Robert,
