* rpc/rpc-lib: rpcsvc should reply when rpc_err is setPranith Kumar K2013-09-111-176/+179
| | | | | | | | | | | | | | | | | | | | | Problem: When requests are received on a connection before setvolume is done, creating frame from the requests fail because there is no association of the transport with the conn(i.e. xl_private). xl_private is set only on set_volume. In such cases error response is not sent from server xlator to that request because of which operations on mount point are hanging. Fix: Set actor return value to RPCSVC_ACTOR_ERROR so that response is sent even in these cases.

* glusterd: Allow bumping down a peer's op-version during probeKaushal M2013-09-101-15/+9
| | | | | | | | | | | | | | | | | | Earlier, a peer running a higher op-version couldn't be probed into a cluster running at a lower op-version. This created issues when trying to expand an upgraded cluster. This patch changes this behaviour. The cluster no longer rejects a peer being probed if its op-version is higher than the cluster op-version. The peer will reduce its op-version if it doesn't have any volumes. If the peer contains volumes and needs to reduce its op-version, it fails the handshake and the probe fails.

* cluster/dht: assign layout onto missing directories tooAnand Avati2013-09-092-4/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | The current self-healing algorithm is ignoring missing directories for assigning new layout. When lookup() is racing against mkdir() or when self-healing a half-done mkdir(), the layout assignment split must happen based on the final number of directories, and not the currently existing number of directories (because we finish mkdir() of missing directories before hash layout assignment). Without this fix, concurrent mkdir() and lookup() will step on each others feet, create a messed up layout on disk, and end up with different in-memory layouts. Once two clients have different in-memory layouts, creation of subdirectory will not arbitrate on the same hashed subvolume and will result in GFID mismatch of the sub-directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | The callback structures in both protocol/client and glusterfsd, gfapi used the same name for the actor table - gluster_cbk_actors. CBKs are required only for the management connection, and the actors of protocol/client are NOP functions. This supposed-to-be NOP function dispatch tabble is actually ending up pointing to the actor table of glusterfsd or gfapi. These functions, even though set wrongly, are not even expected to be called through the protocol/client callback path. Glusterd however sends the FETCHSPEC (and other) notify callbacks to *all* connected clients unconditionally, and there is a small period of time when protocol/client is connected to glusterd for PORTMAP query. If the FETCHSPEC callback notify is issued in this window of time, we end up calling the wrong actor in the client side resulting in a crash.

Thus the intermediate master now makes use of it's own volume information to propogate volume-mark and xtime. On starting Geo-Replication "geo-replication.ignore-pid-check" marker option is enabled, which is an override for the client-pid check in marker. This options triggers marker update only for geo-replication auxillary mount (client-pid == -1). Since gsyncd not does setxattr() directly on the bricks, this option won't trigger a chain of spurious metadata updates that would need to be processed by gsyncd.

Marker too had a check to "not" mark updates for geo-replication's auxillary mounts. With the new geo-replication design, xtimes are not set by the master on the slave for all entities. Due to this cascading setups were broken. This patch introduces "geo-replication.ignore-pid-check" option as a "override" for the client-pid check for gsyncd's client-pid. When this options is enabled, marker start "marking" even if the updates are from the special client. Geo-Replication on the detection of itself being an intermediate master, enables this option.

* gsyncd / geo-rep: Introduce basic crawl instrumentationVenky Shankar2013-09-044-80/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the persistent instrumentation work done by Aravinda (@avishwa), by introducing a handfull of instrumentation variables for crawl. These variables are "pulled up" by glusterd in the event of a geo-replication status cli command and looks something like below: "Uptime=00:21:10;FilesSyned=2982;FilesPending=0;BytesPending=0;DeletesPending=0;" "FilesPending", "BytesPending" and "DeletesPending" are short-lived variables that are non-zero when a changelog is being processes (ie. when an active sync in ongoing). After a successfull changelog process "FilesPending" is summed up into "FilesSynced". The three short-lived variabled are then reset to zero and the data is persisted Additionally this patch also reverts some of the changes made for BZ #986929 (those were not needed).
