Hi,
This is the first time I have tried to expand the storage of a live gluster volume. I was able to get another supermicro storage unit for a gluster cluster that I built. The current clustered storage configuration contains five supermicro units. And the cluster volume is setup with the following configuration:
node-6[/var/log/glusterfs]# gluster volume info
Volume Name: researchdata
Type: Disperse
Volume ID: 93d4-482a-8933-2d81298d5b3b
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (4 + 1) = 5
Transport-type: tcp
Bricks:
Brick1: node-1:/mnt/data/researchdata-1
Brick2: node-2:/mnt/data/researchdata-2
Brick3: node-3:/mnt/data/researchdata-3
Brick4: node-4:/mnt/data/researchdata-4
Brick5: node-5:/mnt/data/researchdata-5
Options Reconfigured:
features.quota-deem-statfs: on
features.inode-quota: on
features.quota: on
storage.fips-mode-rchecksum: on
transport.address-family: inet
nfs.disable: on
locks.mandatory-locking: optimal
Adding the node to the cluster was no problem. But adding a brick using 'add-brick' to the volume resulted in "volume add-brick: failed: Incorrect number of bricks supplied 1 with count 5". So my question is. What would be the correct amount of bricks needed to expand the storage on the current configuration of 'Number of Bricks: 1 x (4 + 1) = 5'? Without reconfiguring the volume all together.
Thanks in advance for any pointers in how to expand this volume's storage capabilities.
