We have an exchange server that has a 430 gb volume ( RAID 5) on which the Databases (4 total) are stored, on which there is about 8 gb of free space. The server also has a volume that is separate from the OS that we use for the Log Files( RAID 1 mirror ). That volume has about 100 gb of free space. the OS Volume (RAID1 mirror) has about 90 gb of free space.
The data bases are quite old and have not been defraged in years, mainly because there has not been anyt8ing wrong with them, they are just growing too large for the drives in the server. I am looking to do two things here... first and foremost, shrink the databases and white space to the least amount possible, and two, re-organize the way we have mail stored in the databases. I would like your input as to perhaps achieve the same but with fewer steps and perhaps less administrator intensive. So here is my plan....
1) move the log files for all 4 data bases to the OS volume. ( this frees up a entire volume)
2) replace the 143 gb drives with 600gb drives and recreate the Mirror (RAID 1)
3) Create a new Storage group and then create some new Databases
4) starting with the largest mail boxes, move them to the newly created databases on the new volume.
5) after all the mailboxes are moved off the database volume, replace the 4 143 gb drives with 4 600gb drives and then recreate the volume
6) using the ESM , move the location of the data bases from the mirror tot he new much larger raid 5.
7) remove the 600gb drives used as the temporary space for the moving of the databases and replace them with the original 143 gb mirror drives as were before we got started.
thank you for your ears eyes and your thoughts.
