iSCSI Disk extent disk usage

[shedoks]

Hi All,

I've just installed FreeNAS-8.3.1-RELEASE-x64 (r13452) and i'm using it as 2nd shared storage for my three esx server.
I've tested it a lot, but somehow i've misedd this strange bug:

My ESX:
~ # du -sh /vmfs/volumes/freenas_10/
631.5G /vmfs/volumes/freenas_10
~ # du -sh /vmfs/volumes/freenas_00/
649.2G /vmfs/volumes/freenas_00

Freenas:
~ # df -h

So where are my files :) ?

In the vmfs filesystem, which appears to be stored on a ZFS device extent.

You could have one of several underlying questions, here, but you failed to ask them. So I'll answer a few and let you figure out what the corresponding question would be.

1) FreeNAS lacks any way to interpret the contents of a vmfs filesystem, which it sees as a stream of disk blocks. You cannot see the files stored by ESXi from the FreeNAS box because of that, but they're stored safely regardless.

2) "zfs list" will show you.

3) "zpool list" is a better way to do that.

And unsolicited commentary: there's a reason for the string "example.org" and it isn't so that you use it in production.
