[Nexus201110141]

Enough Sapce avaialble in datastore but alerts from nworks says that datastore is having 0 KB free space and breached the threshold.

Welcome to the Community,

sounds like a read-only issue. Please double check the permissions for the datastore on your NAS storage.

Welcome to the Communities.

If you are sure that you have disk space it could be how nworks is measuring disk space. An NFS datastore normally creates a thin provisioned disk. Using ls from the command line on the NFS server would show the full provisioned disk size rather than the used space and du would show the size on disk. Make absolutely sure that the datastore does have free space.

Thnx for quick response. Below is the error. Using ESX4.0 U1

When this error comes, it is checked thru ESX console enough space is available.

Critical ------- 12:19:41 12/28/10 smsrv OpsMgr 2007 Managed Application OpsMgr Engyro Description=ESX Host Datastore 'NFS_UnixTD_vmtest2' has breached threshold with only 0 Kb free space remaining. Priority=1 ComputerName= Alert_ID=27c74239-c952-4aa0-af69-6936b9e367f1 MgmtGrp=NEWSINT

Unable to find out from where this alerts are generating. Had a talk with tools team and they gives the workflow how nworks collects data from VC and sent to SCOM.

Engyro is a connector which only forwards alert from SCOM to OVO. There is no role of generating alerts.

SCOM collects all the API from VCenter's and generates alerts on the basis of rule set in Management Pack. We have latest version of Management Pack installed.

Our workflow is :

Nworks connector collect API from Virtual Center and send to SCOM.

SCOM generates alerts on the basis of Management Pack installed.

Engyro forwards alerts from SCOM to OVO.

Currently we are still getting the alerts as stated above.

Please ignore (if you not already did) my previous post. I missed the "nworks". Sorry.

I would try something like http://www.peetersonline.nl/index.php/vmware/get-vmware-disk-usage-with-powershell/ or http://vsential.com/archives/datastore-size-reporting-via-powercli-script/ to give you a better idea of how much provisioned and free space you actually have. If nworks is reporting provisioned space and you have provisioned more than available the alarm may be doing what it was told to do. Check to see what the alarm is measuring. You probably want it to use used space to calculate available free space.
