* glusterd: populate brickinfo->real_path conditionallyAtin Mukherjee2016-04-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/13965 glusterd_brickinfo_new_from_brick () is called from multiple places and one of them is glusterd_brick_rpc_notify where its very well possible that an underlying brick's file system has crashed and a disconnect event has been received. In this case glusterd tries to build the brickinfo from the brickid in the RPC request, however the same fails as glusterd_brickinfo_new_from_brick () fails from realpath. Fix is to skip populating real_path if its a disconnect event.

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The @owner argument tells RPC layer the xlator that owns the connection and to which xlator THIS needs be set during network notifications like CONNECT and DISCONNECT. Code paths that originate from the head of a (volume) graph and use STACK_WIND ensure that the RPC local endpoint has the right xlator saved in the frame of the call (callback pair). This guarantees that the callback is executed in the right xlator context. The client handshake process which includes fetching of brick ports from glusterd, setting lk-version on the brick for the session, don't have the correct xlator set in their frames. The problem lies with RPC notifications. It doesn't have the provision to set THIS with the xlator that is registered with the corresponding RPC programs. e.g, RPC_CLNT_CONNECT event received by protocol/client doesn't have THIS set to its xlator. This implies, call(-callbacks) originating from this thread don't have the right xlator set too. The fix would be to save the xlator registered with the RPC connection during rpc_clnt_new. e.g, protocol/client's xlator would be saved with the RPC connection that it 'owns'. RPC notifications such as CONNECT, DISCONNECT, etc inherit THIS from the RPC connection's xlator.

* glusterd: Fix management encryption issues with GlusterDKaushal M2015-07-131-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport for 01b82c6 from master Management encryption was enabled incorrectly in GlusterD leading to issues of cluster deadlocks. This has been fixed with this commit. The fix is in two parts, 1. Correctly enable encrytion for the TCP listener in GlusterD and re-enable own-threads for encrypted connections. Without this, GlusterD could try to esatblish the blocking SSL connects in the epoll thread, for eg. when handling friend updates, which could lead to cluster deadlocks. 2. Explicitly enable encryption for outgoing peer connections. Without enabling encryption explicitly for outgoing connections was causing SSL socket events to be handled in the epoll thread. Some events, like disconnects during peer detach, could lead to connection attempts to happen in the epoll thread, leading to deadlocks again.

* glusterd: Fix conf->generation to stop new peers participating inAvra Sengupta2015-05-271-0/+3

Backport of http://review.gluster.org/#/c/10895/ Every peer gets a generation number, during it's inception. This generation number is used to identify the peer throiughout it's lifetime. This number is assigned based on the current generation number of the system, which is incremented with every peer that is added. The problem arises when we add a peer, and before it gets a rpc_connect we begin a transaction. In such a case, the peer gets considered in the transaction, but doesn't participate in it coz it isn't connected yet. The moment it gets the rpc notification and is connected, it starts participating in the transaction and all hell breaks loose. To resolve it, we should assign the peerinfo a new generation number everytime it's connected, so that this number will be greater than the generation number that the transaction is acting upon, and even though the peer is connected it will not participate in the transaction. We should also assign the new generation number of the peer to the peerctx, so that the framework that searches for peerinfos based on the generation number, will still function in the same manner.

* glusterd: Replace transaction peers listsKaushal M2015-04-131-18/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Dreyfus2015-04-041-30/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A tiered volume is a normal volume with some number of new bricks representing "hot" storage. The "hot" bricks can be attached or detached dynamically to a normal volume. When this happens, a new graph is constructed. The root of the new graph is an instance of the tier translator. One subvolume of the tier translator leads to the old volume, and another leads to the new hot bricks. attach-tier <VOLNAME> [<replica> <COUNT>] <NEW-BRICK> ... [force] volume detach-tier <VOLNAME> [replica <COUNT>] <BRICK> ... <start|stop|status|commit|force> gluster volume rebalance <volume> tier start gluster volume rebalance <volume> tier stop gluster volume rebalance <volume> tier status The "tier start" CLI command starts a server side daemon. The daemon initiates file level migration based on caching policies. The daemon's status can be monitored and stopped. Note development on the "tier status" command is incomplete. It will be added in a subsequent patch. When the "hot" storage is detached, the tier translator is removed from the graph and the tiered volume reverts to its original state as described in the volume's info file.

* socket: use TCP_USER_TIMEOUT to detect client failures quickerNiels de Vos2015-03-171-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the network.ping-timeout to set the TCP_USER_TIMEOUT socket option (see 'man 7 tcp'). The option sets the transport.tcp-user-timeout option that is handled in the rpc/socket layer on the protocol/server side. This socket option makes detecting unclean disconnected clients more reliable. When the socket gets closed, any locks that the client held are been released. This makes it possible to reduce the fail-over time for applications that run on systems that became unreachable due to a network partition or general system error client-side (kernel panic, hang, ...). It is not trivial to create a test-case for this at the moment. We need a client that unclean disconnects and an other client that tries to take over the lock from the disconnected client.

* glusterd: Protect the peer list and peerinfos with RCU.Kaushal M2015-03-161-39/+150
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Replace libglusterfs lists with liburcu listsKaushal M2015-03-031-22/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces usage of the libglusterfs lists data structures and API in glusterd with the lists data structures and API from liburcu. The liburcu data structes and APIs are a drop-in replacement for libglusterfs lists. All usages have been changed to keep the code consistent, and free from confusion. NOTE: glusterd_conf_t->xprt_list still uses the libglusterfs data structures and API, as it holds rpc_transport_t objects, which is not a part of glusterd and is not being changed in this patch.

* glusterd: op state machine shouldn't use global peer listAtin Mukherjee2014-10-281-0/+5
| | | | | | | | | | | | | | | | | | | | Problem : op state machine was relying on the global peer list while sending lock/stage/unlock commit rpc requests to the peers in the cluster. Trusting on global peer list structure is dangerous as this structure gets modified if any peer modification command is attempted in the cluster when there is a ongoing transaction going through the state machine. An ideal usecase of this problem when rebalance is in progress and peer probe is executed rebalance op-sm and peer probe may run into race making peerinfo structure go for toss. Solution: Use local copy of peer list (xaction_peers) in glusterd op-sm.

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.

It follows it with a more thorough match, by resolving the addresses and comparing addrinfos instead of strings. commit 2542cdbc45aa9cfcaf1f174686158d5565cdd07b Author: Kaushal M <kaushal@redhat.com> Date: Tue Jul 1 17:21:10 2014 +0530 New utility gf_compare_addrinfo commit 338676e8389a44bd91136eebd110197429c2566c Author: Kaushal M <kaushal@redhat.com> Date: Tue Jul 1 14:55:56 2014 +0530 Use gd_peer_has_address instead of strcmp commit 28d45be51f594328741c44455bd80ac9d64ca501 Merge: 728266e 991dd5e Author: Kaushal M <kaushal@redhat.com> Date: Tue Jul 1 14:54:40 2014 +0530 Merge branch 'master' into better-peer-identification commit 728266eb16d5f5a4bf36266044425ae164337f99 Merge: 7d9b87b 2417de9 Author: Kaushal M <kaushal@redhat.com> Date: Tue Jul 1 09:55:13 2014 +0530 Merge remote-tracking branch 'origin/master' into better-peer-identification commit 7d9b87b84955ec17daeaf88a3e7462914039430f Merge: b890625 e02275c Author: Kaushal M <kshlmster@gmail.com> Date: Tue Jul 1 08:41:40 2014 +0530 Merge pull request #4 from vpshastry/better-peer-identification Better peer identification commit e02275c52fb83c72ad082c098fd3e432c2b9c526 Merge: 75ee90d b890625 Author: Varun Shastry <vshastry@redhat.com> Date: Mon Jun 30 16:44:29 2014 +0530 Merge branch 'better-peer-identification' of https://github.com/kshlm/glusterfs into better-peer-identification-kaushal-github commit 75ee90d2f272e49b94d24c9ca4571e89a83055ff Author: Varun Shastry <vshastry@redhat.com> Date: Mon Jun 30 15:36:10 2014 +0530 glusterd: add to the list if the probed uuid pre-exists Signed-off-by: Varun Shastry <vshastry@redhat.com> commit b890625d8164c660695daef3285c67979eef723e Merge: 04c5d60 187a7a9 Author: Kaushal M <kaushal@redhat.com> Date: Mon Jun 30 11:44:13 2014 +0530 Merge remote-tracking branch 'origin/master' into better-peer-identification commit 04c5d60cb938c8d94b214689580b40abb1b0ffcd Merge: 3a5bfa1 e01edb6 Author: Kaushal M <kshlmster@gmail.com> Date: Sat Jun 28 19:23:33 2014 +0530 Merge pull request #3 from vpshastry/better-peer-identification glusterd: search through the list of hostnames in the peerinfo commit 0c64f3346a977f9165ac55a84a1e03c40a7573a7 Merge: e01edb6 3a5bfa1 Author: Varun Shastry <vshastry@redhat.com> Date: Sat Jun 28 10:43:29 2014 +0530 Merge branch 'better-peer-identification' of https://github.com/kshlm/glusterfs into better-peer-identification-kaushal-github commit e01edb63153a1008db70b8fa76ae5b535e099326 Author: Varun Shastry <vshastry@redhat.com> Date: Fri Jun 27 12:29:36 2014 +0530 glusterd: search through the list of hostnames in the peerinfo Signed-off-by: Varun Shastry <vshastry@redhat.com> commit 3a5bfa15855e660db2bfde644727371dd2d618cc Merge: cda6d31 371ea35 Author: Kaushal M <kshlmster@gmail.com> Date: Fri Jun 27 11:31:17 2014 +0530 Merge pull request #1 from vpshastry/better-peer-identification glusterd: Add hostname to list instead of replaceing upon update commit 371ea354f198b4182382d5403c5960c0b2add6b6 Author: Varun Shastry <vshastry@redhat.com> Date: Fri Jun 27 11:24:54 2014 +0530 glusterd: Add hostname to list instead of replaceing upon update Signed-off-by: Varun Shastry <vshastry@redhat.com> commit cda6d3152886623ecbf46baf0048ebe0119b30b6 Author: Kaushal M <kaushal@redhat.com> Date: Thu Jun 26 19:52:52 2014 +0530 Import address lists commit 6649b54aa0440130c08e827e0a1d1bbfb840eca9 Author: Kaushal M <kaushal@redhat.com> Date: Thu Jun 26 19:15:37 2014 +0530 Implement export address list commit 55990034eead92bc9b936240029e460a4bf152d5 Author: Kaushal M <kaushal@redhat.com> Date: Thu Jun 26 18:11:59 2014 +0530 Use first address in list to when setting up the peer RPC. commit a35fde8d19b9988eb04c652fb3a5e4f84d90ad00 Author: Kaushal M <kaushal@redhat.com> Date: Thu Jun 26 18:03:04 2014 +0530 Properly free addresses on glusterd_peer_destroy commit 1988081db09ac9205f3dc7268cef8be267f3ce8b Author: Kaushal M <kaushal@redhat.com> Date: Thu Jun 26 17:52:35 2014 +0530 Restore peerinfo with address list implemented. commit 66f524d5749a12f4910dd6b06c9d91f37e1d831e Author: Kaushal M <kaushal@redhat.com> Date: Mon Jun 23 13:02:23 2014 +0530 Move out all peer related utilities from glusterd-utils to glusterd-peer-utils commit 14a2a326a4dff11b55490dca2a14f39320931340 Author: Kaushal M <kaushal@redhat.com> Date: Tue May 27 12:16:41 2014 +0530 Compilation fix commit c59cd351d0a102d0d5f3ea9001fd33c4edcb262f Author: Kaushal M <kaushal@redhat.com> Date: Mon May 5 12:51:11 2014 +0530 Add store support for hostname list commit b70325f0beb884ad12645ef40185f0bf6cedd741 Author: Kaushal M <kaushal@redhat.com> Date: Fri May 2 15:58:07 2014 +0530 Add a hostnames list to glusterd_peerinfo_t glusterd_peerinfo_new will now init this list and add the given hostname as the lists first member.

* cli/glusterd: Added support for dispersed volumesXavier Hernandez2014-07-111-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two new options have been added to the 'create' command of the cli interface: disperse [<count>] redundancy <count> Both are optional. A dispersed volume is created by specifying, at least, one of them. If 'disperse' is missing or it's present but '<count>' does not, the number of bricks enumerated in the command line is taken as the disperse count. If 'redundancy' is missing, the lowest optimal value is assumed. A configuration is considered optimal (for most workloads) when the disperse count - redundancy count is a power of 2. If the resulting redundancy is 1, the volume is created normally, but if it's greater than 1, a warning is shown to the user and he/she must answer yes/no to continue volume creation. If there isn't any optimal value for the given number of bricks, a warning is also shown and, if the user accepts, a redundancy of 1 is used. If 'redundancy' is specified and the resulting volume is not optimal, another warning is shown to the user. A distributed-disperse volume can be created using a number of bricks multiple of the disperse count.
