* 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).

* geo-rep: Handle copying of common_secret.pem.pub to slave correctly.Kotresh HR2015-01-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current Behaviour: 1. Geo-replication gsec_create creates common_secret.pem.pub file containing public keys of the all the nodes of master cluster in the location /var/lib/glusterd/ 2. Geo-replication create push-pem copies the common_secret.pem.pub to the same location on all the slave nodes with same name. Problem: Wrong public keys might get copied on to slave nodes in multiple geo-replication sessions simultaneosly. E.g. A geo-rep session is established between Node1(vol1:Master) to Node2 (vol2:Slave). And one more geo-rep session where Node2 (vol3) becomes master to Node3 (vol4) as below. Session1: Node1 (vol1) ---> Node2 (vol2) Session2: Node2 (vol3) ---> Node3 (vol4) If steps followed to create both geo-replication session is as follows, wrong public keys are copied on to Node3 from Node2. 1. gsec_create is done on Node1 (vol1) -Session1 2. gsec_create is done on Node2 (vol3) -Session2 3. create push-pem is done Node1 - Session1. -This overwrites common_secret.pem.pub in Node2 created by gsec_create in second step. 4. create push-pem on Node2 (vol3) copies overwrited common_secret.pem.pub keys to Node3. -Session2 Consequence: Session2 fails to start with Permission denied because of wrong public keys Solution: On geo-rep create push-pem, don't copy common_secret.pem.pub file with same name on to all slave nodes. Prefix master and slave volume names to the filename. NOTE: This brings change in manual steps to be followed to setup non-root geo-replication (mountbroker). To copy ssh public keys, extra two arguments needs to be followed. set_geo_rep_pem_keys.sh <mountbroker_user> <master vol name> \ <slave vol name> Path to set_geo_rep_pem_keys.sh: Source Installation: /usr/local/libexec/glusterfs/set_geo_rep_pem_keys.sh Rpm Installatino: /usr/libexec/glusterfs/set_geo_rep_pem_keys.sh Change-Id: If38cd4e6f58d674d5fe2d93da15803c73b660c33 BUG: 1183229 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/9460 Reviewed-by: Aravinda VK <avishwan@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Venky Shankar <vshankar@redhat.com> Tested-by: Venky Shankar <vshankar@redhat.com>

* glusterd: Maintain per transaction xaction_peers list in syncop & mgmt_v3Atin Mukherjee2014-12-225-139/+222
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Please note I've identified this problem in op-sm area as well and a separate patch will be attempted to fix it. Finally thanks to Krishnan Parthasarathi and Kaushal M for your constant help to get to the root cause.

| | | | | | | | | | | | | | | | | | | | | | | | | In glusterd_op_sm(), we lock and unlock the gd_op_sm_lock mutex. Unfortunately, locking and unlocking can happen in different threads (task swap will occur in handler call with use of synctasks). This case is explictely covered by POSIX: the behavior is undefined. http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_mutex_lock.html When unlocking from a thread that is not owner, Linux seems to be fine (though you never know with unspecified operation), while NetBSD returns EPERM, causing a spurious error in tests/basic/pump. To fix this, we use synclock_t which was precisely meant for this. synclock is a pthread_mutex_t like synchronization object which uses the synctask handle for owner and is immune to the task being run on multiple threads during its lifetime.

Also adding a "%s" fmt for portably printing time as simple numeric value on systems regardless of whether 32-bit or 64-bit time_t. Plus a minor tweak to return a ptr to the dest-string to allow gf_time_fmt() to be passed as a param in a *printf(). Someday we should pick the "one true" timestamp format and revise all calls to gf_time_fmt() to use it instead of the five or six different formats.
