How to Add New Storage to dCache

We will look at the example of umfs16, where 12 new pools were added. Following the xfs file system creation, all disks were mounted, cf-agent was run a couple of times to prep the dCache configuration files, then dcache was started, stopped after all pools were enabled, then cf-agent was run a couple of more times to migrate away the metadata.

The poolmanager.conf file was updated in cf3, then propagated to head01 via cf-agent. ssh to the admin domain of head01

• \c PoolManager
• in the PoolManager do "reload -yes"
• start dCache on umfs16
• still in the PoolManager, do
  • rebalance pgroup aglt2UMPools
