Indexing location volume and Index Exclusions
Our EV environment is based on EV 10.0.4, Exchange 2007 SP3 with complete SAN storage based. Archiving run take place each night and backup take place after that.
The open index location drive volume had 23GB space on Tuesday and this 23GB space was taken/gone by Wednesday just in one night. Based on the archiving reports for that night about 14,469 items archived. we use full indexing level
Is it possible for these number of items the indexing consume 23GB of disk space. usually the index drive increase by 100s of MB each night. I tried to locate those index files that created on that night but it does not looks like so many newly files created.
The only thing change on Tuesday was I added a couple of email signature text into the Index Exclusion which is a new feature that comes with SP4. I was kind of so excited about this new feature and thought I should add a couple of exclusions just to see what it does.
