I run my Team Foundation Server inside of Virtual Server 2005 R2. This morning I noticed that the virtual server’s disk usage had gotten over 50GB. That seemed like kind of a lot.
Part of it was a bunch of nightly database backup files for TFS that had accumulated on the virtual disk. That was 9 GBs. (Hint: you should be doing a nightly backup of your TFS SQL Server.)
Something was still using a lot of disk space.
I looked at the data files and log files for SQL Server (C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData). The TfsActivityLogging database’s log file was 30GBs.
Looking around on google, I couldn’t find a straight-forward SQL script on how to truncate and shrink my SQL Server log file.
Here’s the script:
backup log TfsActivityLogging
dbcc shrinkfile (TfsActivityLogging _log, 1)
In case you’re wondering what the next steps are for shrinking the 50gb virtual hard disk:
- From the virtual windows machine, run the disk defrag utility
- Go into the virtual server definition for the virtual machine and mount the precompact.iso
- From the virtual windows machine, run precompact.exe
- Shutdown the virtual machine
- In Virtual Server, “inspect” the virtual machine’s hard disk then choose “compact virtual hard disk”.
