RE: format 2TB rbd device is too slow

Hi Ilya, We can change sector size from 512 to 4096. This can reduce the count of write. I did a simple test: for 900G, mkfs.xfs -f For default: 1m10s Physical sector size = 4096: 0m10s. But if change sector size, we need rbd meta record this. Thanks! Jianpeng -Original Message-

Oh, yeah, we'll definitely test for correctness for async reads on filestore, I'm just worried about validating the performance assumptions. The 3700s might be just fine for that validation though. -Sam On Fri, Aug 28, 2015 at 1:01 PM, Blinick, Stephen L stephen.l.blin...@intel.com wrote: This

This sounds ok, with the synchronous interface still possible to the ObjectStore based on return code. I'd think that the async read interface can be evaluated with any hardware, at least for correctness, by observing the queue depth to the device during a test run. Also, I think
