* glusterd: big lock - a coarse-grained locking to prevent racesv3.4.0alpha3Krishnan Parthasarathi2013-04-171-10/+96
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are primarily three lists that are part of glusterd process, that are concurrently accessed. Namely, priv->volumes, priv->peers and volinfo->bricks_list. Big-lock approach ----------------- WHAT IS IT? Big lock is a coarse-grained lock which protects all three lists, mentioned above, from racy access. HOW DOES IT WORK? At any given point in time, glusterd's thread(s) are in execution _iff_ there is a preceding, inbound network event. Of course, the sigwaiter thread and timer thread are exceptions. A network event is an external trigger to glusterd, via the epoll thread, in the form of POLLIN and POLLERR. As long as we take the big-lock at all such entry points and yield it when we are done, we are guaranteed that all the network events, accessing the global lists, are serialised. This amounts to holding the big lock at - all the handlers of all the actors in glusterd. (POLLIN) - all the cbks in glusterd. (POLLIN) - rpc_notify (DISCONNECT event), if we access/modify one of the three lists. (POLLERR) In the case of synctask'ized volume operations, we must remember that, if we held the big lock for the entire duration of the handler, we may block other non-synctask rpc actors from executing. For eg, volume-start would block in PMAP SIGNIN, if done incorrectly. To prevent this, we need to yield the big lock, when we yield the synctask, and reacquire on waking up of the synctask.

* glusterd: log changes in volume stop (and in op sm codepath)Krutika Dhananjay2013-01-181-50/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes log changes mostly in the op state machine as also in volume stop codepath of glusterd. Changes made: * Moved log level from INFO to DEBUG, of log messages on the various state transitions within a transaction. For example, messages of the following kind: a. "Sent op req to <n> peers" b. "Received LOCK from uuid: <peer-uuid>", etc. * Changed some of the log messages to give as much information as available in case of failure. * Added logs to identify on which machine lock/stage/commit failed. * Quite a few s/THIS/this changes. Also, with this change, log changes in all other volume ops should (hopefully) boil down to modifying the respective logs in handler, stage and commit (and brick ops in some cases).

| | | | | | | | | | | | | | | | | This command is necessary when the local disk/filesystem containing a brick is unexpectedly lost and then recreated. Since 961bc80c, trying to start the brick will fail because the trusted.glusterfs.volume-id xattr is missing, and if we can't start it then we can't replace-brick or self-heal so we're stuck in a permanently degraded state. This command provides a way to label the empty brick with the proper volume ID so that further repair actions become possible.

* glusterd: Fix to log command status at the appropriate timeKrutika Dhananjay2012-09-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: In the existing implementation, the success/failure of execution of a command is decided (and logged) in glusterd handler functions. Strictly speaking, the logging mechanism must take into account what course the command takes within the state machine before concluding whether it succeeded or failed. FIX: This patch attempts to fix the above issue for vol commands. The format of the log message is as follows: for failure: <command string> : FAILED : <cause of failure> for success: <command string> : SUCCESS APPROACH (in a nutshell): * The command string is packed into dict at cli and sent to glusterd. * glusterd logs the command status just before doing a "submit_reply", which is called (either directly or indirectly via a call to glusterd_op_cli_send_response) at 2 places for every vol command: i. in handler functions, and ii. in glusterd_op_txn_complete In short, the failure of a command in the handler implies the command has indeed failed. However, its success in the handler does NOT necessarily mean the command succeeded/will succeed.

* calls to dict_allocate_and_serialize() are not 64-bit cleanKaleb S. KEITHLEY2012-07-121-10/+6
| | | | | | | | | | | | | | | | | | | | | | | All calls to dict_allocate_and_serialize() pass the address of a 32-bit type, but must cast it to the 64-bit pointer type (size_t *). This happens to work on LE machines, but even if it's apparently benign, it's still a bug. On BE machines it is not benign. GF_PROTOCOL_DICT_SERIALIZE() hacks around it by creating a size_t temp var, but that's, well, a hack, IMO when you consider that all the callers are actually passing &<u_int>; the param should just be a u_int * and eliminate the buggy casts and the temp var in the macro. Nobody apparently uses the Fedora/EPEL PPC RPMs, but they might. People are trying to build gluster.org bits on SPARC and tripping over this.

* glusterd: generate node UUID lazilyAnand Avati2012-06-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A commonly faced problem among glusterfs users is: after a fresh installation of glusterfs in a virtual machine, the VM image is cloned to make multiple instances of the server. This breaks glusterd because right after glusterfs installation on the first boot glusterd would have created the node UUID and this gets inherited into the clone. The result is wierd behavior at the time of peer probe where glusterd does not (yet) deal with UUID collisions in a user friendly way. This patch is for the 'prevention' of the issue. The approach here is to avoid generating a UUID on the first start of glusterd, but instead generate a node UUID only when a node UUID is found to be necessary. This naturally avoids the creation of node UUID on first boot and prevents the issue to a large extent. This issue also needs a 'cure' patch, which gives more meaningful error messages to the user and provides CLI to recover from the situations (gluster peer reset?)

* cli: Enable output in XMLKaushal M2012-02-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch enables gluster cli to output data in xml format. XML output can be obtained by passing "--xml" as an argument. A new "volume list" command, which lists the volumes present in a cluster, has been added. This can be used for obtaining a quick list of volumes. Several commands, including "volume top", "volume profile", "volume status" and "volume info", "volume list", have custom XML output routines. Other commands use either one of the 2 generic output routines, cli_xml_output_str() & cli_xml_output_dict(). NOTE: When using "all" for "volume status" and "volume info" the XML output will have multiple roots.
