* Infra to indentify processhari gowtham2017-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: currently we can't identify which process is running and how many instances of it are available. Fix: name the process when its spawned and send it to the server and save it in the client_t The processes that abide by this change from this patch are: 1) fuse mount, 2) rebalance, 3) selfheal, 4) tier, 5) quota, 6) snapshot, 7) brick. 8) gfapi (by default. gfapi.<processname> if processname is found) Note: fuse gets a process name as native-fuse-client by default. If the user gives a name for the fuse and spawns it, it will be of this type --process-name native-fuse-client.<name_specified>. This can be made use by the process like aux mount done by quota, geo-rep, etc by adding another option in the aux mount " -o process-name=gsync_mount" Updates: #178 Signed-off-by: hari gowtham <hgowtham@redhat.com> Change-Id: Ie4d02257216839338043737691753bab9a974d5e Reviewed-on: https://review.gluster.org/17957 Smoke: Gluster Build System <jenkins@build.gluster.org> Tested-by: hari gowtham <hari.gowtham005@gmail.com> Reviewed-by: Amar Tumballi <amarts@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Aravinda VK <avishwan@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>
* glusterfsd: allow subdir mountAmar Tumballi2017-08-041-1/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes: 1. Take subdir mount option in client (mount.gluster / glusterfsd) 2. Pass the subdir mount to server-handshake (from client-handshake) 3. Handle subdir-mount dir's lookup in server-first-lookup and handle all fops resolution accordingly with proper gfid of subdir 4. Change the auth/addr module to handle the multiple subdir entries in option, and valid parsing. How to use the feature: `# mount -t glusterfs $hostname:/$volname/$subdir /$mount_point` Or `# mount -t glusterfs $hostname:/$volname -osubdir_mount=$subdir /$mount_point` Option can be set like: `# gluster volume set <volname> auth.allow "/subdir1(192.168.1.*),/(192.168.10.*),/subdir2(192.168.8.*)"` Updates #175 Change-Id: I7ea57f76ddbe6c3862cfe02e13f89e8a39719e11 Signed-off-by: Amar Tumballi <amarts@redhat.com> Reviewed-on: https://review.gluster.org/17141 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>

* libglusterfs: provide standardized atomic operationsNiels de Vos2017-04-051-22/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current macros ATOMIC_INCREMENT() and ATOMIC_DECREMENT() expect a lock as first argument. There are at least two issues with this approach: 1. this lock is unused on architectures that have atomic operations 2. some structures use a single lock for multiple variables By defining a gf_atomic_t type, the unused lock can be removed, saving a few bytes on modern architectures. Because the gf_atomic_t type locates the lock for the variable (in case of older architectures), each variable is protected the same on all architectures. This makes the behaviour across all architectures more equal (per variable locking, by a gf_lock_t or compiler optimization).

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-15/+34
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

* core: use reference counting for mem_acct structuresJeff Darcy2015-05-091-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When freeing memory, our memory-accounting code expects to be able to dereference from the (previously) allocated block to its owning translator. However, as we have already found once in option validation and twice in logging, that translator might itself have been freed and the dereference attempt causes on of our daemons to crash with SIGSEGV. This patch attempts to fix that as follows: * We no longer embed a struct mem_acct directly in a struct xlator, but instead allocate it separately. * Allocated memory blocks now contain a pointer to the mem_acct instead of the xlator. * The mem_acct structure contains a reference count, manipulated in both the normal and translator allocate/free code using atomic increments and decrements. * Because it's now a separate structure, we can defer freeing the mem_acct until its reference count reaches zero (either way). * Some unit tests were disabled, because they embedded their own copies of the implementation for what they were supposedly testing. Life's too short to spend time fixing tests that seem designed to impede progress by requiring a certain implementation as well as behavior.
