* cluster/afr: Make data selfheal trigger to be configurable.Pranith Kumar K2011-09-081-15/+15
| | | | | | | | | | | | | | | | | | | | By default, lookup triggers data self-heal but that is not the preferred way of operating replicated volumes. We would like the data self heals to be triggered in open instead. Number of back-ground self-heals allowed is 16 and lookups block until self-heal is completed. We want to prevent blocking in fops. We can not make lookups independent of self-heal frames because when there are gfid conflicts the decision of which file is correct is determined in self-heal phase. So in afr, lookup self-heal is going to guarantee name space consistency and open/fd fops will take responsibility for data consistency, these are non blocking. The user needs to set the option cluster.data-self-heal "open" for this behavior.

* Eliminate many "var set but not used" warnings with newer gcc.Jeff Darcy2011-09-071-10/+0
| | | | | | | | | | | | | | | | This fixes ~200 such warnings, but leaves three categories untouched. (1) Rpcgen code. (2) Macros which set variables in the outer (calling function) scope. (3) Variables which are set via function calls which may have side effects.

* cluster/afr: Update fresh_children in lookup if no other ops in progressPranith Kumar K2011-08-191-5/+5
| | | | | | | | | | | | | If write/truncate fails we should remove the child that failed the fop from the fresh children. The previous code assumes that the children that succeeded the fop are fresh children, which is wrong. Fixed that in this patch.
