Is it safe to run Checkdsk on Server2003 file server

Issues with our system yesterday (we had to completely shutdown 2 ESX servers - 16 servers in total and the MSA they all reside on during work hours) have manifested overnight in a ShadowProtect imaging job reporting that the D Drive on one of our file servers is corrupt and saying we need to run Checkdsk to repair it.

My question is, is this able to be done and safe to do while people are accessing the files during the day?  Will it cause us any issues?

Thanks in advance.

If you run chkdsk from a command line with no switches, it runs in "read only" mode.  To repair corrupt data, the volume must be dismounted.  Ergo, you can find the errors, but you cannot fix anything unless your server is offline.

Thanks,

Will schedule an outage at lunchtime today to restart the server and run checkdsk at that point.

Be advised that it may take several hours with 800GB.  If you have the /f or /r it will actually fix the problems and volume will be unavailable during that time.
