RBD - Default block-size=4M

Hi,

In documentation from suse iSCSI-VMWARE i read that i need to reduce the block-size to 1M te get better performance.  Is this also te case with petasan ?  How can i do this ?

Regards

The recommendation as per our VMWare guide is to increase the iSCSI MaxIOSize from 128k to 512k

Reducing the rbd object size from 4->1M can only make a difference if you are writing more than 1M in block size to achieve parallelism, but as stated above the max io size in VMWare is 512k so it will be no use.
