A full list -of bugs that have been addressed is included further below. - -Further, as 3.11 release is a short term maintenance release, features included -in that release are available with 3.12 as well, and could be of interest to -users upgrading to 3.12 from older than 3.11 releases. The 3.11 [release notes](https://gluster.readthedocs.io/en/latest/release-notes/) -captures the list of features that were introduced with 3.11. - -## Major changes and features - -### Ability to mount sub-directories using the Gluster FUSE protocol -**Notes for users:** - -With this release, it is possible define sub-directories to be mounted by -specific clients and additional granularity in the form of clients to mount -only that portion of the volume for access. - -Until recently, Gluster FUSE mounts enabled mounting the entire volume on the -client. This feature helps sharing a volume among the multiple consumers along -with enabling restricting access to the sub-directory of choice. - -Option controlling sub-directory allow/deny rules can be set as follows: -``` -# gluster volume set <volname> auth.allow "/subdir1(192.168.1.*),/(192.168.10.*),/subdir2(192.168.8.*)" -``` - -How to mount from the client: -``` -# mount -t glusterfs <hostname>:/<volname>/<subdir> /<mount_point> -``` -Or, -``` -# mount -t glusterfs <hostname>:/<volname> -osubdir_mount=<subdir> /<mount_point> -``` - -**Limitations:** - -- There are no throttling or QoS support for this feature. The feature will -just provide the namespace isolation for the different clients. - -**Known Issues:** - -- Once we cross more than 1000s of subdirs in 'auth.allow' option, the -performance of reconnect / authentication would be impacted. - -### GFID to path conversion is enabled by default -**Notes for users:** - -Prior to this feature, only when quota was enabled, did the on disk data have -pointers back from GFID to their respective filenames. As a result, if there -were a need to locate the path given a GFID, quota had to be enabled. - -The change brought in by this feature, is to enable this on disk data to be -present, for all cases, than just quota. Further, enhancements here have been -to improve the manner of storing this information on disk as extended -attributes. - -The internal on disk xattr that is now stored to reference the filename and -parent for a GFID is, `trusted.gfid2path.<xxhash>` - -This feature is enabled by default with this release. - -**Limitations:** - -None - -**Known Issues:** - -None - -### Various enhancements have been made to the output of get-state CLI command -**Notes for users:** - -The command `#gluster get-state` has been enhanced to output more information -as below, -- Arbiter bricks are marked more clearly in a volume that has the feature -enabled -- Ability to get all volume options (both set and defaults) in the get-state -output -- Rebalance time estimates, for ongoing rebalance, is captured in the get-state -output -- If geo-replication is configured, then get-state now captures the session -details of the same - -**Limitations:** - -None - -**Known Issues:** - -None - -### Provided an option to set a limit on number of bricks multiplexed in a processes -**Notes for users:** - -This release includes a global option to be switched on only if brick -multiplexing is enabled for the cluster. The introduction of this option allows -the user to control the number of bricks that are multiplexed in a process on a -node. If the limit set by this option is insufficient for a single process, -more processes are spawned for the subsequent bricks. - -Usage: -``` -#gluster volume set all cluster.max-bricks-per-process <value> -``` - -### Provided an option to use localtime timestamps in log entries -**Limitations:** - -Gluster defaults to UTC timestamps. glusterd, glusterfsd, and server-side -glusterfs daemons will use UTC until one of, -1. command line option is processed, -2. gluster config (/var/lib/glusterd/options) is loaded, -3. admin manually sets localtime-logging (cluster.localtime-logging, e.g. -`#gluster volume set all cluster.localtime-logging enable`). - -There is no mount option to make the FUSE client enable localtime logging. - -There is no option in gfapi to enable localtime logging. - -### Enhanced the option to export statfs data for bricks sharing the same backend filesystem - -**Notes for users:** -In the past 'storage/posix' xlator had an option called option -`export-statfs-size`, which, when set to 'no', exports zero as values for few -fields in `struct statvfs`. These are typically reflected in an output of `df` -command, from a user perspective. - -When backend bricks are shared between multiple brick processes, the values -of these variables have been corrected to reflect -`field_value / number-of-bricks-at-node`. Thus enabling better usage reporting -and also enhancing the ability for file placement in the distribute translator -when used with the option `min-free-disk`. - -### Provided a means to resolve GFID split-brain using the gluster CLI -**Notes for users:** - -The existing CLI commands to heal files under split-brain did not handle cases -where there was a GFID mismatch between the files. With the provided enhancement -the same CLI commands can now address GFID split-brain situations based on the -choices provided. - -The CLI options that are enhanced to help with this situation are, -``` -volume heal <VOLNAME> split-brain {bigger-file <FILE> | - latest-mtime <FILE> | - source-brick <HOSTNAME:BRICKNAME> [<FILE>]} -``` - -**Limitations:** - -None - -**Known Issues:** - -None - -### Developer related: Added a 'site.h' for more vendor/company specific defaults -**Notes for developers:** - -**NOTE**: Also relevant for users building from sources and needing different -defaults for some options - -Most people consume Gluster in one of two ways: -* From packages provided by their OS/distribution vendor -* By building themselves from source - -For the first group it doesn't matter whether configuration is done in a -configure script, via command-line options to that configure script, or in a -header file. All of these end up as edits to some file under the packager's -control, which is then run through their tools and process (e.g. rpmbuild) to -create the packages that users will install. - -For the second group, convenience matters. Such users might not even have a -script wrapped around the configure process, and editing one line in a header -file is a lot easier than editing several in the configure script. This also -prevents a messy profusion of configure options, dozens of which might need to -be added to support a single such user's preferences. This comes back around as -greater simplicity for packagers as well. This patch defines site.h as the -header file for options and parameters that someone building the code for -themselves might want to tweak. - -The project ships one version to reflect the developers' guess at the best -defaults for most users, and sophisticated users with unusual needs can -override many options at once just by maintaining their own version of that -file. Further guidelines for how to determine whether an option should go in -configure.ac or site.h are explained within site.h itself. - -### Developer related: Added xxhash library to libglusterfs for required use -**Notes for developers:** - -Function gf_xxh64_wrapper has been added as a wrapper into libglusterfs for -consumption by interested developers. - -Reference to code can be found [here](https://github.com/gluster/glusterfs/blob/v3.12.0alpha1/libglusterfs/src/common-utils.h#L835) - -### Developer related: glfs_ipc API in libgfapi is removed as a public interface -**Notes for users:** - -glfs_ipc API was maintained as a public API in the GFAPI libraries. This has -been removed as a public interface, from this release onwards. - -Any application, written directly to consume gfapi as a means of interfacing -with Gluster, using the mentioned API, would need to be modified to adapt to -this change. - -**NOTE:** As of this release there are no known public consumers of this -API - -## Major issues -1. Expanding a gluster volume that is sharded may cause file corruption - - Sharded volumes are typically used for VM images, if such volumes are - expanded or possibly contracted (i.e add/remove bricks and rebalance) there - are reports of VM images getting corrupted. - - The last known cause for corruption (Bug #1465123) has a fix with this - release. As further testing is still in progress, the issue is retained as - a major issue. - - Status of this bug can be tracked here, #1465123 - -## Bugs addressed - -Bugs addressed since release-3.11.0 are listed below. - -- [#1047975](https://bugzilla.redhat.com/1047975): glusterfs/extras: add a convenience script to label (selinux) gluster bricks -- [#1254002](https://bugzilla.redhat.com/1254002): [RFE] Have named pthreads for easier debugging -- [#1318100](https://bugzilla.redhat.com/1318100): RFE : SELinux translator to support setting SELinux contexts on files in a glusterfs volume -- [#1318895](https://bugzilla.redhat.com/1318895): Heal info shows incorrect status -- [#1326219](https://bugzilla.redhat.com/1326219): Make Gluster/NFS an optional component -- [#1356453](https://bugzilla.redhat.com/1356453): DHT: slow readdirp performance -- [#1366817](https://bugzilla.redhat.com/1366817): AFR returns the node uuid of the same node for every file in the replica -- [#1381970](https://bugzilla.redhat.com/1381970): GlusterFS Daemon stops working after a longer runtime and higher file workload due to design flaws?
