* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

* tests: Self-heald.t spurious failure fixPranith Kumar K2016-03-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | Problem: There is no guarantee that the indices are created by the time write is complete because write-behind may not flush the buffers. Fix: Disable flush-behind so that by the time 'echo abc > file' completes, indices are created. Also removed split-brain-healing.t from spurious failures as we are not able to recreate it.

* Fix bad shell calculation in tests/basiv/afr/self-heald.tEmmanuel Dreyfus2015-01-091-1/+1
| | | | | | | | | | | | | | | | | A shell variable calculation in tests/basiv/afr/self-heald.t resulted in spurious regression failure at test 67. This is wrong and always produce an error: $((`date +"%j"`))%2 This still fails because date +"%j" produces 008, which is considered an octal value: $((`date +"%j"` %2 )) This works: $((`date +"%j"|sed 's/^0*//'` % 2 )) BUG: 1129939 Change-Id: I5d0d27b7bb64ef7d56bafebe71aafe01eb2f39a7 Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org> Reviewed-on: http://review.gluster.org/9414 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* telldir()/seekdir() portability fixesEmmanuel Dreyfus2014-12-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX says that an offset obtained from telldir() can only be used on the same DIR *. Linux is abls to reuse the offset accross closedir()/opendir() for a given directory, but this is not portable and such a behavior should be fixed. An incomplete fix for the posix xlator was merged in http://review.gluster.com/8926 This change set completes it. - Perform the same fix index xlator. - Use appropriate casts and variable types so that 32 bit signed offsets obtained by telldir() do not get clobbered when copied into 64 bit signed types. - modify glfs-heal.c and afr-self-heald.c so that they do not use anonymous fd, since this will cause closedir()/opendir() between each syncop_readdir(). On failure we fallback to anonymous fs only for Linux so that we can cope with updated client vs not updated brick. - Avoid sending an EINVAL when the client request for the EOF offset. Here we fix an error in previous fix for posix xlator: since we fill each directory entry with the offset of the next entry, we must consider as EOF the offset of the last entry, and not the value of telldir() after we read it. - Add checks in regression tests that we do not hit cases where offsets fed to seekdir() are wrong. Introduce log_newer() shell function to check for messages produced by the current script. This fix gather changes from http://review.gluster.org/9047 and http://review.gluster.org/8936 making them obsolete.

* Regression test portability: self-heald.tEmmanuel Dreyfus2014-10-291-8/+12
| | | | | | | | | | | | | | | | | | | | Fix portability problems in updated self-heald.t: - Use the k suffit in dd(1) bs argument instead of less portable M and K - Error message for disconnected bricks in NetBSD is "Socket is not connected" - On touch d/a while bricks are down, NetBSD updates d ctime/mtime even on bricks where a is not present, resulting in a different to-be-healed count than on Linux. We now tes both values. If NetBSD behavior is a bug, it is not in the heal process and should be tested somewhere else. This also requires fixes in heal process: http://review.gluster.org/8936 BUG: 1129939 Change-Id: Ibda1902a8fd64aa7cc5202744adca825e6b251c9 Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org> Reviewed-on: http://review.gluster.org/8968 Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
