Hello,

Right now, in order to quiesce the Guest OS file systems it is required to 
take a VM snapshot.  We would like to avoid taking this snapshot for 
several reasons, most importantly disk space and performance.   So I have 
been looking into how we can manually freeze/thaw the Guest OS (linux) 
file systems.  The goal here is to allow us to perform operations on the 
vmdk file, e.g., backup, while the Guest OS is frozen.

I've looked into the vmsync module, and it looks like we could manually 
call the ioctl to freeze/thaw the file systems.  Has anyone tried this 
before?  Do people think it would work with ESX 4?

Thank you for any help,
Dean
