qos on vmdk file

francoisbnc — Mon, 21 Mar 2016 11:09:26 GMT

Hi,

What is the best method to set qos policy to vmdk files.

Basically the vmdk is located in a nfs exported /volume/qtree and is in a directory.

Vmware manage the name, so the name can contains blanks and specials caracters.

file modify -vserver gdcsvm311 -volume dft_nfs_vmware_sl3wclu12_sys_05 -file "SRV1224 - DB Oracle ETA Dev+Test_2.vmdk" -qos-policy-group medium

Error: command failed: Unable to access file "SRV1224 - DB Oracle ETA Dev+Test_2.vmdk". Reason: File not found

Follow that, I have two problems

1) impossible, as in 7M, to locate the file with a ls command in diag mode.

2) the command "file modify" don't have a qtree parameter, I don't know how the -file parameter must be specified.

Any help appreciated?

François

Hi François,

I did some test with vmdk file and qos.

The command that I used was this:

file modify -vserver vmware_upgrade -volume vmware_upgrade_sata -file /dcfarm01/dcfarm01.vmdk -qos-policy-group test

I think that you miss the "/" character and if you have blank space you can use " character.

After that you can test the qos.

On my side the qos was never applied, after many ticket opened, NetApp had opened a bug (985740).

Tell me if you have more luck.

Regards
Roberto

Hi Roberto,

That worked for me, I had to set policy to -flat vmdk file.

Thanks

Hi François,

the qos on the vmdk works well?

Can you post the correct pattern of the command.

Thanks

Roberto

Hello Roberto,

I used the same command you specified, I had just to use the flat extent vmdk file, no results with the other one.

-rw------- 1 root root 225485783040 Mar 22 14:45 GDC01224 - Cronet DB Oracle ETA Dev+Test_2-flat.vmdk
-rw------- 1 root root 674 Mar 22 01:29 GDC01224 - Cronet DB Oracle ETA Dev+Test_2.vmdk

Best

François
