.Snapshot Grows Up Abnormally

[fernando_rehoyo]

Hi all,

I have a volume configured in a Datastore for VMware. This volume is mounted in NFS and host virtual machines. I have a problem because the .snapshot grows up abnormally.

I think, the origin of my problem is caused by a Virtual Machine (with a strong activity) but I don’t know that.

Somebody knows what is the best method to identify it?

Many thanks for your help

Fernando

Are you sure none of the VMs got deleted? Or possibly some new created without using FlexClone? In both cases your change rate is as big as the size of the VM itself.

Other than that, try to find out if disk defrag wasn't run within the guest OS (or database maintenance?)

Hi all,

Effectively we have many VMs with SQL DB. I think my problem is caused by this DB and too many dumps.

Hi Fernando

one of VM in the datastore must have a very hight write workload. I think you can identify this vm from vmware site. Some 3rd party monitor tools can help you. Like Quest_Foglight-for-Virtualization-Free-Edition-for-VMware

Thanks Gokhan,

I think you are right but I am so sorry because my question is just directed to a Netapp solution.

How to compare the different folders who contain the snapshots ina .snapshot of a volume ?

Best regards

Hi Fernando,

is it block access right? (mean lun, not nfs). You can't decide which vm have a high workload in a lun. lun is a huge file on storage site. we can't see which vm has a high utilization in that lun. I think, if you want tı figure out this issue, you have to analyze this workload from vmware site.

And If you want to see snapshot size, KB change ratio, and RteKB/Hour data, you can use "snap delta" command from storage cli.
