Hey guys, We're running Cassandra with two data directories, let's say /data/sstables1 and /data/sstables2, which are in fact two separate (but identical) disks. The problem is that the disk where "sstables2" is mounted is running out of space and large SSTables stored there cannot be compacted.
So I have two questions: * Can I just move some SSTables data files from "sstables2" to "sstables1" which has much more free disk space? Will Cassandra start fine after that and not lose any data? * Provided multiple data dirs, should Cassandra distribute data equally between them? In what I'm observing this is almost always not true. On that particular node I mentioned above the difference is huge: 4% occupied disk space for "sstables1" and 87% for "sstables2"; on other nodes the situation is a little better but still not 50/50. Thanks! Roman
