[AusNOG] VMWare Snapshot / Delta VMDK removal

[Rory Jones]

As others have said, I wouldn’t go messing around with those VMware files. You have a very high chance of borking something. Instead, get to the source of the problem. Find out *why* your VMs have a sudden appetite for data. Unfortunately I can’t speak for Linux, but on the off chance the suspect VMs are running Windows, there’s an awesome little tool called WinDirStat. For the record, for Mac the equivalent is Disk Inventory X. Run these tools, or the equivalent for your OS. It’ll give you a pretty picture like you’ve just broken Tetris of the contents of the drive. Go for the big blocks first. Find out what they are. Diagnose from there.

Hope this helps someone in the future.

Kind regards,
Rory

Have a QNAP. So moved the pagefile’s to an ISCIS target. And then removed all the Delta’s

Freed up 268gb which has allowed the Veeam backups to run
