/etc/spfs/dsm.opt:
ServerName greenplum
With 2 cluster nodes and 48 segments per node, each node on its own SP node name, Each node during backup will start up to 48 sessions to spectrum protect — so 96. This doubles when client side dedup is used as an out-of-band control session is also start to handle client side dedup chunk queries. So single backup will start near on 200 sessions to the spectrum protect server. This really is because of the way green plum is forcing to parallelism. The “extra” dedup sessions are not started during a restore.
Each node needs to be configured to allow WORKERS in /etc/spfs.opt. So 48 in this case.
gpbackup should NOT be used with — single-data-file or — jobs. Also if doing SP deduplication — no-compression should be set.
