[gpfsug-discuss] question on viewing block distribution across NSDs

[Knister, Aaron S. (GSFC-606.2)[COMPUTER SCIENCE CORP]]

Hi Greg,

You could run an mmdf which will show you how full each NSD is. I'm not sure how to look back in time though to see the fs before the restripe. Do you perhaps have a gpfs.snap you took somewhat recently before the restripe? Maybe an internaldump in /tmp/mmfs somewhere?

Hi All,
               I added some NSDs to an existing filesystem and ran mmrestripefs. I was sort of curious to see what the distribution looked like before and after the restripe. Is there any way of looking at it?

Cheers,

Greg.
