A customer is currently preparing the Linux (Ubuntu) servers that are going to be used to deploy Cassandra and Elastic databases.

He wants to know the recommended way to partition the hard disk on each server. Should all the space go into the '/' file system, or some of it should be assigned to separate 'data' partition, etc?

Please elaborate for each Cassandra and Elastic cases.

Thanks.

Hi Miguel,

For Cassandra:
If you have multiple disks it is better to put your commitlogs and SSTables on a dedicated disk. If you have SSD in your node, it should not be a problem to put it on the same disk.

Other than that there is not really a need to create dedicated partitions.
