[FLASH-USERS] Changing Stripe size

[Kevin (Feng) Chen]

Hi FLASH users,

Recently, we tried to run a 7000 cores Flash job on Stampede @TACC. The problem we ran into a problem that the default strip size was set to 2 on TACC storage system. Therefore the large amount of IO accesses always crash the Metadata server each time a checkpoint file was written.  As such, I was wondering is there any way we can increase the stripe size to 40-50 or even a larger number?

Thanks in advance,

Kevin Chen
