* cli/afr: gluster volume heal info "healed" command output is not appropriateMohit Agrawal2017-10-041-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | Problem: "gluster volume heal info [healed] [heal-failed]" command output on terminal is not appropriate in case of down any volume. Solution: To make message more appropriate change the condition in function "gd_syncop_mgmt_brick_op". Test : To verify the fix followed below procedure 1) Create 2*3 distribute replicate volume 2) set self-heal daemon off 3) kill two bricks (3, 6) 4) create some file on mount point 5) bring brick 3,6 up 6) kill other two brick (2 and 4) 7) make self heal daemon on 8) run "gluster v heal <vol-name>" Note: After apply the patch options (healed | heal-failed) will deprecate from command line.

* glusterd: Introduce option to limit no. of muxed bricks per processSamikshan Bairagya2017-07-101-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a new global option that can be set to limit the number of multiplexed bricks in one process. Usage: `# gluster volume set all cluster.max-bricks-per-process <value>` If this option is not set then multiplexing will happen for now with no limitations set; i.e. a brick process will have as many bricks multiplexed to it as possible. In other words the current multiplexing behaviour won't change if this option isn't set to any value. This commit also introduces a brick process instance that contains information about brick processes, like the number of bricks handled by the process (which is 1 in non-multiplexing cases), list of bricks, and port number which also serves as an unique identifier for each brick process instance. The brick process list is maintained in 'glusterd_conf_t'.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-2/+15
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

* tier : Tier as a servicehari gowtham2017-01-161-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tierd is implemented by separating from rebalance process. The commands affected: 1) Attach tier will trigger this process instead of old one 2) tier start and tier start force will also trigger this process. 3) volume status [tier] will show tier daemon as a process instead of task and normal tier status and tier detach status works. 4) tier stop implemented. 5) detach tier implemented separately along with new detach tier status 6) volume tier volname status will work using the changes. 7) volume set works This patch has separated the tier translator from the legacy DHT rebalance code. It now sends the RPCs from the CLI to glusterd separate to the DHT rebalance code. The daemon is now a service, similar to the snapshot daemon, and can be viewed using the volume status command. The code for the validation and commit phase are the same as the earlier tier validation code in DHT rebalance. The “brickop” phase has been changed so that the status command can use this framework. The service management framework is now used. DHT rebalance does not use this framework. This service framework takes care of : *) spawning the daemon, killing it and other such processes. *) volume set options , which are written on the volfile. *) restart and reconfigure functions. Restart is to restart the daemon at two points 1)after gluster goes down and comes up. 2) to stop detach tier. *) reconfigure is used to make immediate volfile changes. By doing this, we don’t restart the daemon. it has the code to rewrite the volfile for topological changes too (which comes into place during add and remove brick). With this patch the log, pid, and volfile are separated and put into respective directories.

* glusterd: Get maximum supported op-version in a clusterSamikshan Bairagya2017-01-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gluster volume get <VOLNAME> cluster.opversion gives us the current op-version on which the cluster is operating. There is no command that lets the user know the maximum supported op-version that the cluster can run on. This patch adds a new global option cluster.max-op-version, that can be used to retrieve the maximum supported op-version in a cluster. Usage: # gluster volume get all cluster.max-op-version Example output: Option Value ------ ----- cluster.max-op-version 30900 NOTE: The only way to test this feature for now is to set the GD_OP_VERSION_MAX macro to different values (30800 for 3.8,30900 for 3.9, and so on) and rebuild glusterd. Since the regression test framework currently doesn't have support to simulate these tests, there are no accompanying regression tests for this feature. It should be possible to add tests once glusto comes in and makes it easier to run a heterogeneous cluster.

* glusterd : Introduce reset brickAnuradha Talur2016-08-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.

* glusterd: Replace transaction peers listsKaushal M2015-04-131-123/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transaction peer lists were used in GlusterD to peers belonging to a transaction. This was needed to prevent newly added peers performing partial transactions, which could be incorrect. This was accomplished by creating a seperate transaction peers list at the beginning of every transaction. A transaction peers list referenced the peerinfo data structures of the peers which were present at the beginning of the transaction. RCU protection of peerinfos referenced by the transaction peers list is a hard problem and difficult to do correctly. To have proper RCU protection of peerinfos, the transaction peers lists have been replaced by an alternative method to identify peers that belong to a transaction. The alternative method is to the global peers list along with generation numbers to identify peers that should belong to a transaction. This change introduces a global peer list generation number, and a generation number for each peerinfo object. Whenever a peerinfo object is created, the global generation number is bumped, and the peerinfos generation number is set to the bumped global generation. With the above changes, the algorithm to identify peers belonging to a transaction with RCU protection is as follows, - At the beginning of a transaction, the current global generation number is saved - To identify if a peers belonging to the transaction, - Start a RCU read critical section - For each peer in the global peers list, - If the peers generation number is not greater than the saved generation number, continue with the action on the peer - End the RCU read critical section The above algorithm guarantees that, - The peer list is not modified when a transaction is iterating through it - The transaction actions are only done on peers that were present when the transaction started But, as a transaction could iterate over the peers list multiple times, the algorithm cannot guarantee that same set of peers will be selected every time. A peer could get deleted between two iterations of the list within a transaction. This problem existed with transaction peers list as well, but unlike before now it will not lead to invalid memory access and potential crashes. This problem will be addressed seprately.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* glusterd: Protect the peer list and peerinfos with RCU.Kaushal M2015-03-161-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The peer list and the peerinfo objects are now protected using RCU. Design patterns described in the Paul McKenney's RCU dissertation [1] (sections 5 and 6) have been used to convert existing non-RCU protected code to RCU protected code. Currently, we are only targetting guaranteeing the existence of the peerinfo objects, ie., we are only looking to protect deletes, not all updaters. We chose this, as protecting all updates is a much more complex task. The steps used to accomplish this are, 1. Remove all long lived direct references to peerinfo objects (apart from the peerinfo list). This includes references in glusterd_peerctx_t (RPC), glusterd_friend_sm_event_t (friend state machine) and others. This way no one has a reference to deleted peerinfo object. 2. Replace the direct references with indirect references, ie., use peer uuid and peer hostname as indirect references to the peerinfo object. Any reader or updater now uses the indirect references to get to the actual peerinfo object, using glusterd_peerinfo_find. Cases where a peerinfo cannot be found are handled gracefully. 3. The readers get and use the peerinfo object only within a RCU read critical section. This prevents the object from being deleted/freed when in actual use. 4. The deletion of a peerinfo object is done in a ordered manner (glusterd_peerinfo_destroy). The object is first removed from the peerinfo list using an atomic list remove, but the list head is not reset to allow existing list readers to complete correctly. We wait for readers to complete, before resetting the list head. This removes the object from the list completely. After this no new readers can get a reference to the object, and it can be freed.

* glusterd: Maintain per transaction xaction_peers list in syncop & mgmt_v3Atin Mukherjee2014-12-221-56/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current implementation xaction_peers list is maintained in a global variable (glustrd_priv_t) for syncop/mgmt_v3. This means consistency and atomicity of peerinfo list across transactions is not guranteed when multiple syncop/mgmt_v3 transaction are going through. We had got into a problem in mgmt_v3-locks.t which was failing spuriously, the reason for that was two volume set operations (in two different volume) was going through simultaneouly and both of these transaction were manipulating the same xaction_peers structure which lead to a corrupted list. Because of which in some cases unlock request to peer was never triggered and we end up with having stale locks. Solution is to maintain a per transaction local xaction_peers list for every syncop.

* gluster: Fix the recursive goto outs in the source code.Avra Sengupta2014-07-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Added a script check_goto.pl, that when run from the source code root, will scan all .c files to match the following pattern: label: if (condition) goto label; On finding such a pattern the script will print the file name and the line number. There are certain cases where the above recursive pattern is intended. Hence adding those labels to ignore-labels. Thanks Vijaikumar Mallikarjuna for the perl script.

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.

* glusterd: Better op-version values and rangesKaushal M2014-06-091-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Till now, the op-version was an incrementing integer that was incremented by 1 for every Y release (when using the X.Y.Z release numbering). This is not flexible enough to handle backports of features into Z releases. Going forward, from the upcoming 3.6.0 release, the op-versions will be multi-digit integer values composed of the version numbers, instead of a simple incrementing integer. An X.Y.Z release will have XYZ as its op-version. Y and Z will always be 2 digits wide and will be padded with 0 if required. This way of bumping op-versions allows for gaps in between the subsequent Y releases. These gaps will allow backporting features from new Y releases into old Z releases.
