Exchange 2003 Disk Space problem and Log Files
I've got a sticky situation at school whereby the Exchange Server (2003) has about couple of weeks life left in it.
When I started the job a month ago I discovered that it has a RAID disk fault and the DB hasn't been backed up for almost a year (the Event viewer is also flagging inconsistencies in the DB)
Obviously the Transaction Logs have built up (80gb worth !) and is chewing up disk space on the C Drive.
My challange being I am unable to back up the DB (I've tested backing up a small file (50mb) on NT Backup and it froze) the server is sluggish and copying say 4 gb worth of data onto D Partition takes 30 minutes. I suspect this is due to the RAID fault
So I'm worried the server will crash doing any disk intense activity (ie moving the Transaction log files path, or trying a full backup)
My question is thus, I know it's a bad idea to delete log files manually but how likely are log files from say back in April 2011 are still not committed to the DB?
I suppose I could dismount the DB and run eseutil to see what log files are needed, but would it remount again?? Damn I can't do a backup either !
We will be migrating next week to a new Exchange 2010 server but I read in MS that when migrating mailboxes you will get a big increase in log file size at the Exchange Server 2003 side as well as 2010? (in some cases 1:1 they say which means transfering mailboxes would fill up Exchange 2003's log disk !
No mans land really lol.
