* fuse-bridge: fix posix-only configurationAnand Avati2012-11-192-0/+31
| | | | | | | | | | | | | | Recent changes in fuse-resolver had broken the use case of having a trivial configuration with only storage/posix translator. Fix it and include a regression test to avoid breakage in the future.

* fuse: handle mountflags properlyNiels de Vos2012-11-194-14/+47
| | | | | | | | | | | | | | | | | | | | | | The internal mount API had no access to the generic mountflags used by mount(2). Thus the "ro" mount option that needs to be passed down to mount(2) as as a mountflag was incorrectly mangled into the fuse-specific mount parameter string (cf. http://review.gluster.com/655). This commit fixes the internal API and the "ro" issue. It also adds a check for the "rw" and "ro" mount options in tests/basic/mount.t. Thanks to Csaba Henk (csaba@) for suggestions and proposing an updated patch.

* object-storage: final changes to remove swift diffPeter Portante2012-11-1637-669/+311
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Final set of changes to remove the diffs carried to make UFO work with OpenStack Swift. The code is now a complete layering on top of OpenStack Swift where we either "monkey patch" or subclass as necessary. See BZ 870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589). There are a lot of changes here due for the most part to rearranging the directory hierarchy to have create a proper python module hierarchy under the "gluster" namespace. Plugin references have been removed. The differences that used to be in the swift.diff file are now replaced with server implementations for account, container, object, and proxy that subclass the swift versions. Additionally, the plugins/conf directory has been moved to the "etc" directory, and the plugins/bin directory promoted a level. Unit tests pass. A new setup.py file is provided so that the install process can use it for creating all the necessary python install infrastructure (eggs and paste support). A new RPM spec file is provided which to properly install the new code, and the sample configuration files have been modified to reference the new python egg.

* object-storage: refactor to use swift devicesPeter Portante2012-11-1623-243/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor code to use the devices configuration file setting for account, container, and object servers, dropping mount_path from the fs.conf file, and constructing new account, container and object server rings. This removes the next to last set of diffs in the swift diff file. See BZ 870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589). The key to the change is the dropping of the pre-built account, container and object rings, instead providing a script that will generate them for the user given the gluster volume name in use. In addition, we override the Swift check_mount() method and replace it with Gluster's which attempts to "auto-mount" if it is not already mounted. The following is an enumeration of the changes contained in this refactoring: * The refactoring to override the Swift check_mount() involved condensing a lot of code, removing redundancies and simplifying methods across a number of modules * Drop checking the mount point in the low level DiskDir, DiskAccount and DiskFile objects now that Swift's normal mount checking is used, and enable it by default in the template configuration file * Add missing get_container_timestamp() method for DiskAccount objects * Fix the plugin RPM spec file to provide the new ring builders, and while we were at it, finally fix the over-writing of the configuration files on install * Bug fixes * The monkey patched version of check_object_creation was not working correctly due to a missing import of HTTPBadRequest and a bad reference to validate_obj_name_component() * Only have the utils module import the plugins constraints module for the side effect of monkey patching if gluster is enabled * Removed the db_file.db file in the tree since it is created on the fly * Updated 2011 copyright notices to 2012 Change-Id: I8f4454576b1423021c9bbf3c36176f8db51e62c0 BUG: 870589 Signed-off-by: Peter Portante <peter.portante@redhat.com> Reviewed-on: http://review.gluster.org/4179 Reviewed-by: Pete Zaitcev <zaitcev@redhat.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Tested-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Mohammed Junaid <junaid@redhat.com>

* object-storage: swift-diff removal: hide obj onlyPeter Portante2012-11-164-72/+47
| | | | | | | | | | | | | | | | | | | | | | | Towards swift-diff removal: hide object_only behavior inside DiskDir class objects. See BZ 870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589) One of the last few reasons for having the swift diff is the need to update the account and container information from the file system when the configuration is not for object-only use (meaning, other updates to the file system can come from clients other than UFO, which means UFO currently has to generate the necessary metadata for each request instead of caching it). This change moves that logic into the DiskDir class methods so that the container and account server code does not have to track that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes to make DiskAccount subclass DiskDir complete. This change helps reduce the diffs ahead of further refactoring. Note that DiskDir initializes all the same fields as DiskAccount, plus a few more, and ends up reading the metadata properly, while only adding a couple of fields not used for account purposes. This change also passes the account controller's logger for use by the DiskAccount class. Along the way we: * Remove the redundant update_account() method in the DiskCommon base class, since the update_container() method in DiskDir performs the exact same functionality * Remove the initialization of variables ahead of assignments in two cases, and also move the initialization of the list variables closer to where they are used * Collapse the imports from swift.plugins.utils into one statement * Use a temporary directory for the db_file.db when we find ourselves in a unit test environment Change-Id: I4dc59b416a66393adfe0ed32c7a62c79731d70c0 Signed-off-by: Peter Portante <peter.portante@redhat.com> Reviewed-on: http://review.gluster.org/4172 Reviewed-by: Pete Zaitcev <zaitcev@redhat.com> Tested-by: Pete Zaitcev <zaitcev@redhat.com> Reviewed-by: Mohammed Junaid <junaid@redhat.com>

This is one more step closer to removing our dependency on modifying the Swift code directly with these changes. See It is also the first step to acknowledging that we are not a plugin, but a layering on top of Swift. The major piece of work here is based on a recognition that the plugins/Glusterfs.py module provided a Glusterfs class that instantiated instances of an object that always contained the same data from the configuration file. The fields of such an object were not being changed and were treated as read-only in all cases. Since the object's data was the same for all instantiations there was no need to pass the data from the glusterfs filter all the way down into the bowels of the Gluster_DiskFile and DiskDir objects. Taking advantage of the nature of that data, we now just have those fields read into module variables, and change the Glusterfs object methods into module level functions. Much of the changes result from the consequence of making that switch from object to module. Here are a few other changes made along the way: * Bump the release numbers in the spec files in recognition of these changes * Create the plugins/fs_utils.py module so that the methods in the plugins/Glusterfs.py module don't have to include plugins/utils.py, which would create a circular dependency * Note that this dependency comes from methods in plugins/utils.py depending on the module level constructs in plugins/Glusterfs.py so that we only store those values in one place * Changed plugins/DiskDir.py:DiskDir class to not check for, and/or optionally create, the /etc/swift/db_file.db at run time, just create it a module init time * Removed the duplicate strip_obj_storage_path() from plugins/DiskDir.py and utils.py and move it to the Glusterfs module * Used os.path.join in plugins/DiskDir.py where possible * Renamed the .conf files to .conf-gluster so that we don't clobber existing config files * This is not a complete change, as the spec file also needs to be modified to avoid the clobbering * See also https://bugzilla.redhat.com/show_bug.cgi?id=865867 * Removed the redundant DIR_TYPE definition in plugins/utils.py * Removed MOUNT_PATH from plugins/utils.py replacing references with that from Glusterfs * This actually fixes a bug if a user every used a different mount path from the default in fs.conf * Added ASYNCDIR definition to plugins/utils.py until such time as another refactoring can rely on the one from swift.obj.server * Renamed plugins/utils.py's plugin_enabled() function to Gluster_enabled() * The diffs we carry for Swift are now a bit smaller in that we no longer have to add the plugin() method, we don't have to keep a fs_object field in these objects, and we can reference the Glusterfs module directly * Unit tests were modified appropriately, but now need to be run in the context of a Swift tree; this is unfortunate, but further refactoring will address this Change-Id: Id5d2510d56364761c03b3979bc71187dbe2f82fe BUG: 870589 Signed-off-by: Peter Portante <peter.portante@redhat.com> Reviewed-on: http://review.gluster.org/4141 Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Mohammed Junaid <junaid@redhat.com> Tested-by: Kaleb KEITHLEY <kkeithle@redhat.com>

* 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.
