  1. Optional - To distribute Aster vWorkers across multiple data disks, create a /home/beehive/config/vWorkerDiskList file on every worker node in the cluster. The file must be created before the instance is started, and should contain a comma-separated list of disks found on the individual worker node. Ensure that there are no spaces between the list of disks. For example: tdh233e1:~ # cat /home/beehive/config/vWorkerDiskList /data1,/data2,/data3,/data4,/data5,/data6,/data7,/data8 Distribution of vWorker nodes across multiple data disks will take effect only if a non-empty vWorkerDiskList file is present under the required directory path. The vWorkerDiskList file can be added after a softshutdown and, in that case, the distribution of vWorker nodes will then take effect following a softstartup or a softrestart. If the file is not present, the vWorkers for that worker node will not be distributed.
