* distribute: bring in feature to fix the layout of root inodeAmar Tumballi2010-09-231-1/+143
| | | | | | | | | | | | | | | | | * If the errno is ESTALE for root, fuse doesn't send fresh lookup on the path (it does for all other inodes). Earlier layout mismatch for root never used to happen inside codebase, and if noticed, it was serious issue. Now with DVM, after a add-brick or a remove-brick, layout can be changed even for 'root' inode. Needed to fix this issue inside distribute itself, instead of fuse sending 'fresh' lookup on root.

* nfs, nfs3: Base volume access on CHILD-UP-DOWN eventShehjar Tikoo2010-09-227-105/+418
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overall, the aim of this patch is to change the result of an nfs op depending on whether the underlying volume is up or down as notified by CHILD_UP and CHILD_DOWN events. This patch contains three intertwined changes: o Only when the lookup on the root of a volume is successful does gnfs now export the subvolume. Till now the result of the lookup was not used to determine whether we should export that volume. Not accounting for root lookup failure resulted in ESTALEs on first access because some children of distribute were down at the time of the root lookup. o Only when lookups on all the subvolumes have succeeded are these exports enabled through NFS. o When a child of say distribute goes down, on CHILD_DOWN event nfs will ignore all incoming requests from the client because ignoring these will prevent ESTALEs for those requests and in the hope that ignoring the requests will make the client retransmit. There are risks in this approach absent the DRC but we're willing to live with that for now. When a child goes down, the mount exports list will continue to show it but mount requests will be denied.
