I have an ESXi box that was configured - we had created a couple of snapshots over the past month just as we were setting up the box - the other night the server ran out of space even though there should have been about 150gb of free space.
Once we managed to get into it we noticed that there was a file about 130gb big with filename000XX.vmdk in the datastore but it was for the date the server crashed. We did not create a snapshot.
We had an error in the events saying not enough room for redo file.
What is this redo file / how does it work.
I read if I delete these files I lose data unless I commit the data so how do i do that.
How can I prevent this happening going forward.
I really appreciate any help people can give.
