Hello,

SAN HQ and the EqualLogic Group Manager report only 10% left space on one of our EqualLogic 6210xs volumes. We have two VMWare VMs with thin disks residing on that volume. No snapshot space used or reserved.

The vSphere client reports a totally different amount of space left (much more).

I understand that a block storage device cannot be aware of the correct amount of space beeing used on the volume by the OS. Is that correct?

If so, I ask myself why this function (show space utilization) was implemented in first place in storage managers if it cannot work reliable at this level?

Should I instead deactivate all kind of volume reports and warnings at storage layer and delegate this function to the OS (in my case create respective alarms in vsphere client for space utilization)?

Thanks a lot.

Best regards

Martin
