See BZ 868120: http://bugzilla.redhat.com/show_bug.cgi?id=868120 Basically the redundant routines restore_object, restore_account and restore_container have been collapsed to one routine, restore_metadata, which will only write out metadata if the new metadata is different from what was originally read.

* object-storage: reduce the number of getxattr system calls by onePeter Portante2012-10-256-13/+281
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial step towards addressing BZ 865619. Prior to the patch, reading metadata for a given object or container involves at minimum three getxattr system calls for objects that use only one xattr key/value pair: 1. (via pyxattr) getxattr() to see if key exists and get its value length (so it can allocate memory for second call below) 2. (from pyxattr) getxattr() to get actual value data 3. (via pyxattr) getxattr() to see if following key exists For objects and containers that only have to use one xattr key/value pair, this patch reduces the number system calls by one. This can be significant given that almost every Swift API operation requires reads of the object or containers metadata. This patch is mostly a change to plugins.utils.read_metadata() to try to unpickle the accumulated metadata as each key/value pair is read, rather than trying to accumulate all the key/value pairs and unpickle at the end. Once we get enough data to form the pickle, we no longer keep trying to get more keys, even if those keys exist. The extra keys can exist when the size of the stored metadata shrinks below a key threshold. See https://bugzilla.redhat.com/show_bug.cgi?id=865619 for more details. See also https://bugzilla.redhat.com/show_bug.cgi?id=865858. This patch also adds a unit test infrastructure, and uses it to test with full coverage, the read_metadata, write_metadata and clean_metadata functions. As a result, we found that an infinite loop would occur in clean_metadata() when an unexpected IOError would occur trying to remove a key (this patch contains a fix).

* object-storage: Bump size of metadata stored per xattr keyPeter Portante2012-10-251-2/+3
| | | | | | | | | | | | | | | | | | | For Gluster, since we require XFS, and XFS has a max metadata value size of 64 KB, use the increased stored size to reduce the number of system calls, and how often we exit and enter the Python interpreter (via calls to pyxattr module). Today, with the hardcoded 254 byte limit per xattr key/value pair, adding a couple hundred bytes of user specified metadata can translate to up to three xattr key/value pairs (remember that the internal python metadata dictionary is pickled first and then stored in chunks in the keys).

* Add OCF compliant resource agents for glusterd and volumesFlorian Haas2012-10-245-1/+481
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These resource agents plug glusterd into Open Cluster Framework (OCF) compliant cluster resource managers, like Pacemaker. The glusterd RA is fairly trivial; it simply manages the glusterd daemon like any upstart or systemd job would, except that Pacemaker can do it in a cluster-aware fashion. The volume RA is a bit more involved; It starts a volume and monitors individual brick's daemons in a cluster aware fashion, recovering bricks when their processes fail. Note that this does NOT imply people would deploy GlusterFS servers in pairs, or anything of that nature. Pacemaker has the ability to deploy cluster resources as clones, meaning glusterd and volumes would be configured as follows in a Pacemaker cluster: primitive p_glusterd ocf:glusterfs:glusterd \ op monitor interval="30" primitive p_volume_demo ocf:glusterfs:volume \ params volname="demo" \ op monitor interval="10" clone cl_glusterd p_glusterd \ meta interleave="true" clone cl_volume_demo p_volume_demo \ meta interleave="true" ordered="true" colocation c_volume_on_glusterd inf: cl_volume_demo cl_glusterd order o_glusterd_before_volume 0: cl_glusterd cl_volume_demo The cluster status then looks as follows (in a 4-node cluster; note the configuration above could be applied, unchanged, to a cluster of any number of nodes): ============ Last updated: Fri Mar 30 10:54:50 2012 Last change: Thu Mar 29 17:20:17 2012 via crmd on gluster02.h Stack: openais Current DC: gluster03.h - partition with quorum Version: 1.1.6-3.el6-a02c0f19a00c1eb2527ad38f146ebc0834814558 4 Nodes configured, 4 expected votes 8 Resources configured. ============ Online: [ gluster02.h gluster03.h gluster04.h gluster01.h ] Clone Set: cl_glusterd [p_glusterd] Started: [ gluster02.h gluster03.h gluster04.h gluster01.h ] Clone Set: cl_volume_demo [p_volume_demo] Started: [ gluster01.h gluster02.h gluster03.h gluster04.h ] This is also a way of providing automatic glusterd and brick recovery in systems where neither upstart nor systemd are available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Framework for writing test cases to be submitted with patches. This framework and the test cases get exercised by Jenkins in the pre-commit regression test. Jenkins is configured to give a +1 verified vote only if the regression test passes without failures (which includes test cases added/changed by the patch being tested) Every patch should include a test case (either extensions/changes to existing test cases or add new ones, as appropriate). The test case should be part of the same commit so that both code and test case get reviewed together. Test cases added are cumulative. Every new patch gets tested against its own test case and every test case previously added. A lot of new commits in the near future will be pure test cases (with no code change) which will get added in "catch up" mode. The tool used for implementing test cases is 'prove', and the framework itself is modeled similar to the POSIX compliance filesystem test suite. Under the top level directory, a new directory named 'tests/' is added. This contains top level classifier directories and framework files/scripts. Functionality tests should be created under a classifier directory below 'tests/'. For e.g: tests/basic/mount.t tests/performance/write-behind.t Bugs which get fixed should include a test case script named by the bug id, so that we are guaranteed any new change will not bring the issue back. For e.g: tests/bugs/bug-123456.t Triggering of regression tests in Jenkins is manual at this point as we do not want the entire test suite to run against every revision of a patch while it is still in the review/resubmit cycle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The upstream Swift code base contains the following commit which adds the ability to modify constraint values using the swift.conf file: https://github.com/openstack/swift/commit/a2ac5efaa64f57fbbe059066c6c4636dfd0715c2 These changes rely on the above commit being back-ported to Swift 1.4.8 (see https://github.com/portante/swift/commit/fc2421b04022ac6bbe9d5014362ec5f99f94c5e0). As a result, a good number of differences we carry can be removed, since the provided swift.conf file now contains the values we need. Along with these changes, we add middleware to get constraints loaded properly (via monkey patching) until subclassing is implemented in a future commit. We further simplify the diffs to a minimal set by storing the timestamp in file system metadata and moving new files to the plugins/middleware directory. Note that the original "gluster" middleware was in the swift.diff file, and has been renamed to "glusterfs" and moved to the new plugins/middleware directory. The "gluster" middleware is now a temporary way to get the constraints properly loaded (both of these middleware pieces should disappear in future commits when we refactor further to subclass the Swift objects instead of patching them).

* Remove the test subdirectory diffs ahead of initial refactoring.Peter Portante2012-10-161-136/+0
| | | | | | | | | | | | | | | | | | A subsequent commit will refactor the changes required of Swift to be much more minimal in nature, but does so by relying on an upstream Swift change to allow constraint values specified in the swift.conf file (see https://github.com/openstack/swift/commit/a2ac5efaa64f57fbbe059066c6c4636dfd0715c2). As a result, we can remove the test subdirectory diffs and assume that they will be present as a result of the upstream patch above.

* Fix BZ 865858: remove unnecessary system calls around xattr opsPeter Portante2012-10-131-73/+19
| | | | | | | | | | | | | | | | | The following is a simple refactoring of the read and write metadata methods to just make calls to get/set/remove xattr operations instead of trying to stat/open/close the file. For a single GET operation, this brings down the number of system calls made from 13 to 3 for a file object with no significantly sized metadata (meaning, only 1 xattr key/value pair is needed to store the metadata).

* cluster/afr: gluster volume heal $VN info sporadically reports nothing to healVenkatesh Somyajulu2012-10-111-24/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: Whenever rsync is done at the mount point of a replicate volume and during the rsycn glusterd and bricks of one of the machine gets killed then executing gluster volume heal info gives results sporadically.Sometimes it says Number of entries are zero and other time it gives different output. When glusterd and brick of one of the machine gets killed then at other machine, RPC_CLNT_DISCONNECT will get triggered periodically. So it may happen that during the execution of gluster volume heal info command, RPC_CLNT_DISCONNECT also gets triggered and glusterd will assume that it got a new rpc_disconnet notification and glusterd will call the glusterd_op_ac_send_unlock_drain function instead of calling the glusterd_op_ac_rcvd_brick_op_acc function which is responsible for printing the entries. So because of RCP_CLNT_DISCONNECT notification, glusterd will execute functions responsible for RPC_CLNT_DISCONNECT(glusterd_op_ac_send_unlock_drain) rather than executing functions responsible for gluster volume heal info command(glusterd_op_ac_rcvd_brick_op_acc). FIX: Put a condition in for RPC_CLNT_DISCONNECT in the glusterd_peer_rpc_notify function so that if RPC_DISCONNECT is triggered for the first for a peer then glusterd mark that peer as disconnected so that if RPC_DISCONNET is triggered again, because peer is already marked as disconnected, glusterd will not inject EVENTR_ACK_DRAIN and prints the Number of entries.
