[gpfsug-discuss] Spectrum Scale - how to get RPO=0

Hi Tom,

>>we are trying to implement a mixed linux/windows environment and we have one thing at the top - is there any global method to avoid asynchronous I/O and write everything in >>synchronous mode?

If the local and remote sites have good inter-site network bandwidth and low-latency, then you may consider using GPFS synchronous replication at the file-system level (-m 2 -r 2).  The Spectrum Scale documentation (link below) has further details.

Hello everyone,
we are trying to implement a mixed linux/windows environment and we have one thing at the top - is there any global method to avoid asynchronous I/O and write everything in synchronous mode?
Another thing is - if there is no global sync setting, how to enforce sync i/o from linux/windows client?

Greetings
Tom Rachobinski
