We have a 2 node Cassandra cluster with a replication factor of 2. The load factor on the nodes is around 350Gb
Datacenter: Cassandra ========== Address Rack Status State Load Owns Token -5072018636360415943 172.31.7.91 rack1 Up Normal 328.5 GB 100.00% -7068746880841807701 172.31.7.92 rack1 Up Normal 351.7 GB 100.00% -5072018636360415943 However,if I use df -h, /dev/xvdf 252G 223G 17G 94% /HDD1 /dev/xvdg 493G 456G 12G 98% /HDD2 /dev/xvdh 197G 167G 21G 90% /HDD3 HDD1,2,3 contains only cassandra data. It amounts to close to 1Tb in one of the machine and in another machine it is close to 650Gb. I started repair 2 days ago, after running repair, the amount of disk space consumption has actually increased. I also checked if this is because of snapshots. nodetool listsnapshot intermittently lists a snapshot but it goes away after sometime. Can somebody please help me understand, 1. why so much disk space is consumed? 2. Why did it increase after repair? 3. Is there any way to recover from this state. Thanks, Rahul
