* mgmt/glusterd: Correct the log path of valgrind.He Min2020-01-061-1/+1
| | | | | | | | | | | | | | | | | Problem: Currently enabling run-with-valgrind will cause the gnfs and quota to fail to start. The phenomenon is as follows. ------------------------------------------------------------------------------ NFS Server on localhost 2049 0 N 48406 Quota Daemon on localhost N/A N/A N 48428 ------------------------------------------------------------------------------ Solution: The cause of the above phenomenon is that the log path of valgrind is set incorrectly. Gnfs and quota can start with valgrind normally after correcting the log path. Updates: #788 Change-Id: Ib91408c08522ff66afff908fbff3fce4b93ea770 Signed-off-by: He Min <hemin@cmss.chinamobile.com>

| | | | | | | | | | | | | We were ruturning first proc entry even if it is not running. This was in an assumption that the process could have just started and not updated the pidfile. Now we that we have introduced the states for process state, we can take decision based on that.

* glusterd/shd: Change shd logfile to a unique nameMohammed Rafi KC2019-06-241-2/+2
| | | | | | | | | | | | | | | | With the shd mux changes, shd was havinga a logfile with volname of the first started volume. This was creating a lot confusion, as other volumes data is also logging to a logfile which has a different vol name. With this changes the logfile will be changed to a unique name ie "/var/log/glusterfs/glustershd.log". This was the same logfile name before the shd mux Change-Id: I2b94c1f0b2cf3c9493505dddf873687755a46dda fixes: bz#1721601 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* mgmt/shd: Implement multiplexing in self heal daemonMohammed Rafi KC2019-04-011-54/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Shd daemon is per node, which means they create a graph with all volumes on it. While this is a great for utilizing resources, it is so good in terms of performance and managebility. Because self-heal daemons doesn't have capability to automatically reconfigure their graphs. So each time when any configurations changes happens to the volumes(replicate/disperse), we need to restart shd to bring the changes into the graph. Because of this all on going heal for all other volumes has to be stopped in the middle, and need to restart all over again. Solution: This changes makes shd as a per volume daemon, so that the graph will be generated for each volumes. When we want to start/reconfigure shd for a volume, we first search for an existing shd running on the node, if there is none, we will start a new process. If already a daemon is running for shd, then we will simply detach a graph for a volume and reatach the updated graph for the volume. This won't touch any of the on going operations for any other volumes on the shd daemon. Example of an shd graph when it is per volume graph ----------------------- | debug-iostat | ----------------------- / | \ / | \ --------- --------- ---------- | AFR-1 | | AFR-2 | | AFR-3 | -------- --------- ---------- A running shd daemon with 3 volumes will be like--> graph ----------------------- | debug-iostat | ----------------------- / | \ / | \ ------------ ------------ ------------ | volume-1 | | volume-2 | | volume-3 | ------------ ------------ ------------ Change-Id: Idcb2698be3eeb95beaac47125565c93370afbd99 fixes: bz#1659708 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* core: implement a global thread poolXavi Hernandez2019-02-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a thread pool that is wait-free for adding jobs to the queue and uses a very small locked region to get jobs. This makes it possible to decrease contention drastically. It's based on wfcqueue structure provided by urcu library. It automatically enables more threads when load demands it, and stops them when not needed. There's a maximum number of threads that can be used. This value can be configured. Depending on the workload, the maximum number of threads plays an important role. So it needs to be configured for optimal performance. Currently the thread pool doesn't self adjust the maximum for the workload, so this configuration needs to be changed manually. For this reason, the global thread pool has been made optional, so that volumes can still use the thread pool provided by io-threads. To enable it for bricks, the following option needs to be set: config.global-threading = on This option has no effect if bricks are already running. A restart is required to activate it. It's recommended to also enable the following option when running bricks with the global thread pool: performance.iot-pass-through = on To enable it for a FUSE mount point, the option '--global-threading' must be added to the mount command. To change it, an umount and remount is needed. It's recommended to disable the following option when using global threading on a mount point: performance.client-io-threads = off To enable it for services managed by glusterd, glusterd needs to be started with option '--global-threading'. In this case all daemons, like self-heal, will be using the global thread pool. Currently it can only be enabled for bricks, FUSE mounts and glusterd services. The maximum number of threads for clients and bricks can be configured using the following options: config.client-threads config.brick-threads These options can be applied online and its effect is immediate most of the times. If one of them is set to 0, the maximum number of threads will be calcutated as #cores * 2. Some distributions use a very old userspace-rcu library (version 0.7) for this reason, some header files from version 0.10 have been copied into contrib/userspace-rcu and are used if the detected version is 0.7 or older. An additional change has been made to io-threads to prevent that threads are started when iot-pass-through is set.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

| | | | | | | | | | | | | | | | | | | | | In a previous patch (https://review.gluster.org/20769) we've added the key length to be passed to dict_* funcs, to remove the need to strlen() it. This patch moves some xlators to use it. - It also adds dict_get_int32n which was missing. - It also reduces the size of some key variables. They were set to 1024b or PATH_MAX, where sometimes 64 bytes were really enough. Please review carefully: 1. That I did not reduce some the size of the key variables too much. 2. That I did not mix up some keys. Compile-tested only! Change-Id: Ic729baf179f40e8d02bc2350491d4bb9b6934266 updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com>

* glusterd: Gluster should keep PID file in correct locationGaurav Kumar Garg2017-08-111-4/+5
| | | | | | | | | | | | | | | | | | | | | | | Currently Gluster keeps process pid information of all the daemons and brick processes in Gluster configuration file directory (ie., /var/lib/glusterd/*). These pid files should be seperate from configuration files. Deletion of the configuration file directory might result into serious problems. Also, /var/run/gluster is the default placeholder directory for pid files. So, with this fix Gluster will keep all process pid information of all processes in /var/run/gluster/* directory.

* glusterd: initialize the daemon services on demandAtin Mukherjee2015-07-271-13/+2
| | | | | | | | | | | | | | | | | | | | | | As of now all the daemon services are initialized at glusterD init path. Since socket file path of per node daemon demands the uuid of the node, MY_UUID macro is invoked as part of the initialization. The above flow breaks the usecases where a gluster image is built following a template could be Dockerfile, Vagrantfile or any kind of virtualization environment. This means bringing instances of this image would have same UUIDs for the node resulting in peer probe failure. Solution is to lazily initialize the services on demand.
