How to check local partition /tmp /var size in esxi5

[suhag79]

Hi,

I m trying to run vm-support command with /tmp to dump the log in /tmp but unable to do so due to space issue in /tmp/....when i run the df -h command, i can see that local datastore is having 10 GB free space but i can not see /tmp /var partition size seperatety. Please see attached snap. Could u pl let me know how to check /var and /tmp size.

Thanks.

ESXi runs from a RAMdisk locally. You can get information about the ramdisk free space with these commands:

# vdf -h

# esxcli system visorfs ramdisk list

You can just dump the vm-support bundle to your local datastore as well.

Thank You for helpful post.

How we can check that ESXi is running from RAMDISK and is their any disadvantage of this.

There is no way to "check", it always does. The actual hard disk data it boots from are the vfat partitions you see with df -h.

It takes that data and builds a RAMdisk it uses for runtime.
