| | | | | | | | | | | | | | | | | | | | | Problem: read-only/worm translator is not loaded by default in brick graph because of which when read-only option is set through volume set volume still remains writable untill the bricks are restarted as the translator does not have an inmemory flag to decide whether the read-only/worm option is turned or not. Solution: read-only/worm should be loaded by default in brick graph and the read-only/worm option can be toggled through volume set command. read-only/worm translator now' has an in-memory flag to decide whether the volume is read-only or not and based on that either reject the fop or proceed.

Avati which can be found @ https://gist.github.com/avati/af04f1030dcf52e16535#sharding-xlator-stripe-20 Still to-do: * complete implementation of inode write fops - [f]truncate, zerofill, fallocate, discard * introduce transaction mechanism in inode write fops * complete readv * Handle open with O_TRUNC * Handle unlinking of all shards during unlink/rename * Compute total ia_size and ia_blocks in lookup, readdirp, etc * wind fsync/flush on all shards Note: Most of the items above are related. Once we come up with a clean way to determine the last shard/shard count for a file/file size and the mgmt of sparse regions of the file, implementing them becomes trivial.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A dummy translator has been introduced as a place holder for functions related to managing NFS-Ganesha exports. A volume set option is introduced to manage volume level exports. gluster vol set <volname> ganesha.enable ON/OFF 1. gluster volume set <volname> ganesha.enable ON It creates the export config file with a unique export ID. Sends a DBus signal to export this volume dynamically. 2. gluster vol set <volname> ganesha.enable OFF Unexports the specific volume. Deletes the specfic config file related to the volume. This change also removes the handling of the older keys "nfs-ganesha.enable" and "nfs-ganesha.host" Change-Id: I8d4a0b542326a6a0c8e4711600b106274d666587 BUG: 1188184 Signed-off-by: Meghana Madhusudhan <mmadhusu@redhat.com> Reviewed-on: http://review.gluster.org/9585 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* socket: use TCP_USER_TIMEOUT to detect client failures quickerNiels de Vos2015-03-172-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This change was developed on the git branch at [2].

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.

Addition of debug xlators into the brick graph is also handled by this walk. As a result, a lot of cruft that is present in the exisiting implementation of this function gets cleaned up. 4. get_server_xlator() now makes use of server_graph_table to determine whether a xlator key corresponds to a server xlator or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | Replace brick: If geo-replication was configured on a volume, replace brick used to fail. This patch allows replace brick to go through if all geo-rep sessions corresponding to that volume is stopped. Remove brick: There was no check for geo-replication for remove brick. Enforce 'remove brick commit' to fail if geo-rep session corresponding to volume is running. Allow 'remove brick commit' only if all of the geo-rep sessions corresponding to that volume is stopped. Code is re-organized for better readability.

* epoll: Adding the ability to configure epoll threadsShyam2015-02-071-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to configure the number of event threads for various gluster services. Currently with the multi thread epoll patch, it is possible to have more than one thread waiting on socket activity and processing the same. This thread count is currently static, which this commit makes dynamic. The current services which use IO path, i.e brick processes, any client process (nfs, FUSE, gfapi, heal, rebalance, etc.a), gain 2 set parameters to control the number of threads that are processing events. These settings are, - client.event-threads <n> - server.event-threads <n> The client setting affects the client graph consumers, and the server setting affects the brick processes. These are processed and inited/reconfigured using the client/server protocol xlators. Other services (say glusterd) would need to extend similar configuration settings to take advantage of multi threaded event processing. At present glusterd is not enabled with this commit, as it does not stand to gain from this multi-threading (as I understand it).
