Dear All,
I have an ESXi 5.1 host running about a single dev VM. The local datastore is 400GB mirrored array and I am using thin provisioning there to allow me to have about 450GB of disk space. (there was a second VM running on this machine that is no longer used)
Recently I have seen a the available disk space in the datastore decrease quite sharply, and I am trying to track down where the space is being consumed, I am assuming it is the VMDKs. If I look at the datastore, the time/date stamps on the .VMDKs none of them seem to have been touched for a while (2-3 months) yet in the last week 5GB of free space has been used in the datastore. Other files in the data store which have been changed in the last week are the log files, but these are quite small (10's of MB for logs), Or the memory swap files, (but I thought these were static in size.)
So I was wondering if there is an event log for disk space allocation that I could check somewhere. Or is there somewhere else I should be checking for the consumption of disk space (files not shown in the datastore, files in the host OS for instance.)
The reason I ask is that I ran out of disk space last week and had to delete a VM and it .VMDKs to get some operational space back. What I don't understand is there would appear to be plenty of free space on the disks, just not sure where the disk space is going.
EG the disks are:
Volume 1:
Datastore says it is 162,529,300 KB in size and 156,264,400 KB is provisioned.
Windows says it is a 156,287,996 KB sized volume and there is nearly 50GB free.
This equates to 68.5% of provisioned space in use.
Volume 2:
Datastore says it is 267,386,900 KB in size and 210,852,900 KB is provisioned.
Windows says it is a 267,386,848 KB in size and there is about 165GB free
This equates to 44.75% of provisioned space in use.
Any insights?
Thanks in advance,
Jim
