* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-0424-267/+267
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* features/shard: Introducing sharding translatorKrutika Dhananjay2015-03-192-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | Based on the high-level design by Anand V.

* afr: arbiter xlatorRavishankar N2015-03-192-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the arbiter translator into the tree. This is a server side xlator used for replica 3 volumes. It sits above posix and will be loaded on the 3rd (last) brick of every afr subvolume in a replica 3 configuration. It intercepts inode read/write operations: reads are unwound with ENOTCONN, inode writes are unwound with success without actually passing them down to posix. Metadata operations are allowed to pass through. The CLI for creating a 3 way replica with arbiter is also added but kept disabled (A 'normal' 3 way replica is created instead). This patch is a part of the arbiter logic implementation for 3 way AFR, details of which can be found at http://review.gluster.org/#/c/9656/ Change-Id: I395b81f49d5da52c466daf5c8518f1bbad9c16fa BUG: 1199985 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/9840 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* glusterd: CLI commands to create and manage tiered volumes.Dan Lambright2015-03-1910-32/+438
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 M2015-03-1618-290/+801

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. This change was developed on the git branch at [2]. This commit is a combination of the following commits on the development branch. d7999b9 Protect the glusterd_conf_t->peers_list with RCU. 0da85c4 Synchronize before INITing peerinfo list head after removing from list. 32ec28a Add missing rcu_read_unlock 8fed0b8 Correctly exit read critical section once peer is found. 63db857 Free peerctx only on rpc destruction 56eff26 Cleanup style issues e5f38b0 Indirection for events and friend_sm 3c84ac4 In __glusterd_probe_cbk goto unlock only if peer already exists 141d855 Address review comments on 9695/1 aaeefed Protection during peer updates 6eda33d Revert "Synchronize before INITing peerinfo list head after removing from list." f69db96 Remove unneeded line b43d2ec Address review comments on 9695/4 7781921 Address review comments on 9695/5 eb6467b Add some missing semi-colons 328a47f Remove synchronize_rcu from glusterd_friend_sm_transition_state 186e429 Run part of glusterd_friend_remove in critical section 55c0a2e Fix gluster (peer status/ pool list) with no peers 93f8dcf Use call_rcu to free peerinfo c36178c Introduce composite struct, gd_rcu_head [1]: http://www.rdrop.com/~paulmck/RCU/RCUdissertation.2004.07.14e1.pdf [2]: https://github.com/kshlm/glusterfs/tree/urcu Change-Id: Ic1480e59c86d41d25a6a3d159aa3e11fbb3cbc7b BUG: 1191030 Signed-off-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.org/9695 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Anand Nekkunti <anekkunt@redhat.com> Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Krishnan Parthasarathi <kparthas@redhat.com>

* snapshot: append timestamp with snapnameMohammed Rafi KC2015-03-101-19/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Appending GMT time stamp with snapname by default. If no-timestamp flag is given during snapshot creation, then time stamp will not append with snapname; Initial consumer of this feature is Samba's Shadow Copy feature. This feature allows Windows user to get previous revisions of a file. For this feature to work snapshot names under .snaps folder (USS) should have timestamp in following format appended: @GMT-YYYY.MM.DD-hh.mm.ss PS: https://www.samba.org/samba/docs/man/manpages/vfs_shadow_copy2.8.html This format is configurable by Samba conf file. Due to a limitation in Windows directory access the exact format cannot be used by USS. Therefore we have modified the file format to: _GMT-YYYY.MM.DD-hh.mm.ss Snapshot scheduling feature also required to append timestamp to the snapshot name therefore timestamp is appended in snapshot creation itself instead of doing the changes in snapview server.
