Updating an action replay d link dir 655 validating identity
After you create a Storage Group in the Exchange Management Console, we have an empty directory on disk.
The only thing that actually happens is setting a property for the Storage Group in Active Directory, so no log files have been created yet.
The offline copy of the database has also been checked for consistency.
Remember what I wrote in my previous article: “everything is logged in the log files, even the creation of database files!
” If you dismount the database, delete the database file “mailbox database.edb” or whatever name you have given the database and try to mount the database again, the following error is raised: As you can see both the log file signature and the database signature match, so these files belong together.
When you (accidentally) create a new mailbox you will find other information in the database header: As you can see the log signature hasn’t changed (still the same set of log files) but the database has a new signature, meaning that although the database has the same name and it is in the same location it is a new database!
The first three steps do not need any further explanation. When dismounting the database all information in the log files that is not yet committed to the database is flushed to the database file. You can check in the database header information when the database was dismounted by looking at the “last detach” information.
