* nfs: persistent caching of connected NFS-clientsNiels de Vos2013-08-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce /var/lib/glusterfs/nfs/rmtab to contain a list of NFS-clients which have a volume mounted. The volume option 'nfs.mount-rmtab' can be set to an alternative filename. When the file is located on shared storage, multiple gNFS servers can use the same file to present a single NFS-server. This cache is read when a system administrator calls 'showmount -a' and updated when an NFS-client calls MNT or UMNT from the MOUNT protocol. Usage: - create a volume for storing the shared rmtab file - mount the volume on all storage servers, at the same location - make sure that the volume is mounted at boot (add to /etc/fstab) - place the rmtab file on the volume: # gluster volume set <VOLUME> nfs.mount-rmtab <MOUNTPOINT>/<FILENAME> - any subsequent mount requests will add an entry to this file - 'showmount -a' requests will return the NFS-clients using the cluster Note: The NFS-server does currently not support reconfigure(). When a configuration option is set/changed, the NFS-server glusterfs process gets restarted. This causes the active NFS-clients to be forgotten (the entries are saved in the old rmtab, but we do not have a reference to that file any more, so we can't re-add them). Therefor a re-mount done by the NFS-clients is needed before they get listed in the rmtab again.

| | | | | | | | | | | | | By doing a lookup, we get a chance to do all of the self-heal checks that would occur if we were using native protocol, and return proper status if the self-heal fails.

* libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridgeBrian Foster2012-07-171-26/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
