Hey Guru's- I have an Exchange 5.5, sp4 with the priv.edb running out of hard drive space but there looks like there is an opportunity to reclaim about 1/4 to 1/3 of the drive back if I do an offline defragmentation. Currently, my pub.edb and log files are on d:\exchsrvr\mdbdata and my priv.edb is on e:\. I plan on doing the following: 1-Do a complete backup, then stop all services 2-Migrate the priv.edb to a much larger g:\ drive (which is already installed) using perfomance optimizer, 3-and run the following command: "eseutil /d g:\exchsrvr\mdbdata\priv.edb /ld:\exchsrvr\mdbdata /te:\exchsrvr\mdbdata\tempdfrg.edb" 4-Delete all log files from d:\exchsrvr\mdbdata 5-Run Isinteg -priv -fix -test alltests 6-Start all services and test. 7-Eventually, migrate the priv.edb back to the original mirrored drive e:\. My question is in step 4. Deleting the log files. I am reading from my old notes last year where I had to run the repair option on the Priv.edb due to severe corruption. I know that offline defragmentation creates a new copy of the database, so the signatures do not match the log files. None of the Microsoft documenation that I can find says specifically to delete the log files before starting any services so I'm a bit concerned. Any KB articles y'all can point me to would be gratefully appreciated. thanks, Greg CONFIDENTIALITY NOTICE: This e-mail message, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential information and privileged information.
