D.4.2 Creating a File System

Use the pdfsmkfs command to create a DFS. Execute the pdfsmkfs command at the master server.

The parameters to be specified in pdfsmkfs are the parameter values determined in advance as described at "D.1 File System Design".

The DFS creation example below is for the following environment:

Representative partition:	/dev/disk/by-id/scsi-1FUJITSU_300000370106
File data partition:	/dev/disk/by-id/scsi-1FUJITSU_300000370107 /dev/disk/by-id/scsi-1FUJITSU_300000370108
Master server (primary):	master1
Master server (secondary):	master2

# pdfsmkfs -o dataopt=y,blocksz=8388608,data=/dev/disk/by-id/scsi-1FUJITSU_300000370107,data=/dev/disk/by-id/scsi-1FUJITSU_300000370108,node=master1,master2 /dev/disk/by-id/scsi-1FUJITSU_300000370106 <Enter>

Note

Specify the node option of the pdfsmkfs command in the final option.

Refer to pdfsmkfs under "Appendix A Command Reference" in the "Primesoft Distributed File System for Hadoop V1 User's Guide" for details of each option.
