For the last couple of days, the sis changelog on one particular volume that contains VMware datastores keeps filling up. We have several VMware datastore volumes and this is only happening on this one volume. It's one of the smaller ones at 250 GB. i re-run the volume efficiency start with -scan-old-data set to true to clear the error, but I can't figure out why it keeps occurring. This is an AFF system with inline dedupe/compression on, and scheduled dedupe which takes about 5 - 6 minutes. I did change the scheduled dedupe time to twice a day instead of once but that didn't clear the issue. Any ideas?
