You can copy all of the sstables into any given data directory without issue (keep them within the keyspace/table directories, but the mnt/mnt2/mnt3 location is irrelevant).
You can also stream them in via sstableloader if your ring topology has changed (especially if tokens have moved) From: Gerard Maas Reply-To: "user@cassandra.apache.org" Date: Thursday, August 6, 2015 at 9:50 AM To: "user@cassandra.apache.org" Subject: Duplicating a cluster with different # of disks Hi, I'm currently trying to duplicate a given keyspace on a new cluster to run some analytics on it. My source cluster has 3 disks and corresponding data directories (mnt, mnt2, mnt3) but the machines in my target cluster only have 2 disks (mnt, mnt2). What should be the correct procedure to copy the sstable data from source to destination in this case? -kr, Gerard.
