ERROR:

ANR1812E DELETE FILESPACE VMFULL failed because replication

DESCRIPTION:

Decommed VMs fail to auto-delete during expiration because replication is happening. In an ideal world, there would be enough system resources to perform DB Backup in 2 hours, expiration in 2 hours, and replication in 4-8 hours. In this environment, replication overlaps a lot of other processes, and can get in the way. 

ANR1812E DELETE FILESPACE VMFULL-SOMENODENAME for node failed deletion because of a replication in progress. (SESSION: 123456)

WORKAROUND:

Identify the server

Cancel replication
CANCEL REPLICATION

Identify the filespace
VMFULL-SOMENODENAME in the example

Find the node that owns the filespace.

CAUSE:

Replicate Node, a normal operation, creates locks on any filespace to be processed.

The long-term resolution would be to have enough system resources to not have to overlap daily operations processes.

The benchmark set by IBM for this would be the ability to complete BACKUP DB in 2 hours.  This environment take 8-12 hours for most servers.
