| | | | | | | | | | | | | | | | | | Enable exporting directories as separate exports. Even though the directories wont show up in showmount output, they'll still be mount'able. The new option: nfs.export-dirs <on|off> is enabled by default so that users dont have to wait till this option is incorporated into the gluster command line.

* nfs, nfs3: Base volume access on CHILD-UP-DOWN eventShehjar Tikoo2010-09-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* nfs: Support directory level exportsShehjar Tikoo2010-07-041-45/+649
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nfsx has followed traditional approach of exporting whole volumes as NFS exports. The Platform requires and some users have approached us for introducing exports of only specific directories instead of full Gluster volumes. This commit introduces this support through two nfsx options: Option 1: ========= option nfs3.<volume-name>.export-dir <subdir1-in-vol>,<subdir2-in-vol>,..<subdirN-in-vol> export-dir will allow the export of a particular dir as a single export by itself. For eg.: volume posix type storage/posix option directory /export/ end-volume volume posix-ac type features/access-control subvolumes posix end-volume volume nfs type nfs/server subvolumes posix-ac option rpc-auth.addr.allow * option nfs3.posix-ac.export-dir /homes/shehjart end-volume A comma separate list of sub-directories will set up those dirs as separated exports. At the nfs client, the mount command will be: $ mount <nfsserver>:/posix-ac/homes/shehjart /mnt Option 2: ========= option nfs3.<volume-name>.export-volumes <on|off> There can be situations where users only want the directory level exports and require that volume exports be completely disabled. The above option allows us to do this. By default, volume exports are enabled. From the earlier example, replacing <volume-name> with posix-ac, will disable mounting of the posix-ac volume as a whole. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.

* nfs: Redesign fop argument passing to support single volfile useShehjar Tikoo2010-04-021-9/+6
| | | | | | | | | | | | | | | | | | | | | The current design of the interaction between the generic NFS layer and the protocol handlers like mount3 and nfs3 is such that it does not allow using a single volume file which contains the nfs/server and the protocol/server. This is because the common nfs-fops layer assumes that ctx->top is always the nfs/server. This is wrong. The fops layer needs access to top because top or rather the generic NFS xlator's private state has a mem-pool. The fops layer needs this mem-pool to get memory for storing per-fop state. Since the fops layer cannot anymore take ctx->top be the nfs/server, all layers need to start passing the nfs/server xlator_t right down to the fops layer. I am also taking this chance to remove the synchronous equivalents of the fops and also remove the dirent caching directory operations.
