Setting Up config file

bricks=/bricks/brick1/,/bricks/brick2/,/bricks/brick3/,/bricks/brick4/,/bricks/brick5/,/bricks/brick6/,/bricks/brick7/
vol_name=test

Where hosts is the IP or hostnames of the peers in the gluster cluster, bricks are the paths to mount points where the bricks are mounted and vol_name is the base name of all the volumes. Edit the example.conf file available in the project folder.

Example commands

1. Creating 10 EC volumes.

BulkVolumeCreate -f example.conf -t ec -e 2x4+2 -n 10

2. Creating 100 arb volumes.

BulkVolumeCreate -f example.conf -t arb -e 1x2+1 -n 100

3. Creating 20 replica 3x3 volumes with prefix hi_.

BulkVolumeCreate -f example.conf -t rep -e 3x3 -n 20 -p hi

BulkVolumeCreate --config_file example.conf --type ec --expression 2x4+2 --number 10
BulkVolumeCreate --config_file example.conf --type arb --expression 1x2+1 --number 100
BulkVolumeCreate --config_file example.conf --type rep --expression 3x3 --number 20 --pefix hi
