The disk capacity available to different generations of Teradata Viewpoint servers might be different. When clustering, if the active cache database has more disk capacity than the standby cache database, set a disk quota so that the active cache database does not use up more space than is available on the standby cache database.
- To make sure that enough disk capacity is available to the cache database, run df -h /data.
If the capacity on the active cache database is greater than on the standby cache database, run the following command on the active cache database server to limit the capacity used (replace number of GBs with the limit, in Gigabytes, for the drive):
setquota -u postgres 0 <number of GBs>000000 0 0 /data
