[Lustre-discuss] What exactly is punch statistic?

[Mervini, Joseph A]

Hi Cliff - it's been a long time...

It seems to me that file truncation is a bad thing - i.e., file writes are not completed. Is this an invalid assessment?

Thanks,
Joe

Hi,

I have been covertly trying for a long time to find out what punch means as far a lustre llobdstat output but have not really found anything definitive.

Can someone answer that for me? (BTW: I am not alone in my ignorance... :) )

Thanks.
