Exchange 2010 Corrupt Log File
Question 0 Sign in to vote Our Exchange 2007 server has a corrupt transaction log event log file is corrupted windows 2003 file. It was picked up by the Symantec Backup Exec store backup duringverification of the log file. The server error numbers are 483 General, mount exchange 2010 database without log files 440 Logging/Repair, and 305 Log File Validation. I am thinking the best way to handle this is to 1) dismount the database 2)shut downexchange services 3)run Eseutil /mh 4) run Eseutil /d 5) delete all of thetransaction log

Thanks - If the log file that's damaged is one that contains only committed transaction then it isn't needed to bring the database back to a consistent state after you dismount that database. Assuming you have only one database in the storage group, if the "eseutil /mh" shows the dtabase to be in a consistent state you can move (don't copy) all the log files and the chk file to another directory and remount the database. That will start a new log file generation. Make a backup of the storage group as soon as you can. Once you're happy the backup is okay and things are running okay you can remove those old log and chk files. There shouldn't be any need to use "eseutil /d". --- Rich Matheisen

got corrupted😦 OK, no longer an issue, posting it in here in case someone in the future comes across this, it might help them. This should also work if you delete the e0xx.log file in MDBDATA directory of exchange, and cannot start Exchange. *************************OK, so Microsoft Exchange 2k creates log file that records every transaction. Saves it in the MDBDATA directory, generaly as E0000##.log. When it gets to 5,120k, it stops, and creates another file sequentially numbered. When the backups run at night, Veritas deletes the files so they don't fill up the hard drive. My server usually generates about 25 of these files an hour during the busy parts of the day. (Figure it should be lower, but it must be spam coming in, I've checked and we're not an open relay) It's a normal routine, something that doesn't need daily monitoring or anything. On Tuesday I'm doing some poking around the server, we use one of the drives for saving setup files and a few other things that aren't used too often, and I like to go in and probe around and see if there are any obsolete versions of setup files that I can delete, and I notice the server only has 400MB of free space on the D drive (where exchange is installed) and on the M drive (Exchange's virtual drive) This is alarming, since there is normally about 8 gigs free, so I check the information store, it's at 11 gigs. I check to see who the largest mailboxes are (marketing department) and I ask them to clear out some old e-mails, especially back-and-forth conversations that carried imbedded images each time it was replied to, stuff like that. As she does it I'm watching the free disk space drop and drop. I investigate, and the E00000X.log file is at 7 gigs. And climbing. For some reason, it stopped breaking itself into new files after 5 megs. And because it was still in use, Veritas couldn't delete it. Strangely, nothing in the Backup logs indicating the file was skipped for being in use. s--. This can't be good. Wednesday I do some research, and run an extra database backup, but it was too late, on Thursday just after lunch the server ran out of hard drive space and the stores dismounted. I dropped the Swap File size dedicated to the D drive from 1024mb to 512 mb, this would free up 500 MB to get everything back up so people can go about their business while I search for a solution. This requires a reboot, so I warned everyone that the IM system would be down for a few minutes, and no one was bothered, since E-mail was already down. I reboo
