[gpfsug-discuss] Replication settings when running mmapplypolicy

[Buterbaugh, Kevin L]

Hi All,

I haven’t been able to find this explicitly documented, so I’m just wanting to confirm that the behavior that I’m expecting is what GPFS is going to do in this scenario…

I have a filesystem with data replication set to two.  I’m creating a capacity type pool for it right now which will be used to migrate old files to.  I only want to use replication of one on the capacity pool.

My policy file has two rules, one to move files with an atime > 30 days to the capacity pool, to which I’ve included “REPLICATE(1)”.  The other rule is to move files from the capacity pool back to the system pool if the atime < 14 days.  Since data replication is set to two, I am thinking that I do not need to explicitly have a “REPLICATE(2)” as part of that rule … is that correct?  I.e., I’m wanting to make sure that a file moved to the capacity pool which therefore has its’ replication set to one doesn’t keep that same setting even if moved back out of the capacity pool.

Thanks…

Kevin
