[gpfsug-discuss] cpu shielding

[Matt Weil]

All,

We are seeing issues on our GPFS clients where mmfsd is not able to
respond in time to renew its lease. Once that happens the file system is
unmounted.  We are experimenting with c groups to tie mmfsd and others
to specified cpu's.  Any recommendations out there on how to shield GPFS
from other process? 

Our system design has all PCI going through the first socket and that
seems to be some contention there as the RAID controller with SSD's and
nics are on that same bus.

Thanks

Matt
