Release notes for Gluster 3.11.0
This is a major Gluster release that includes some substantial changes. The features revolve around, improvements to small file workloads, SE Linux support, Halo replication enhancement from Facebook, some usability and performance improvements, among other bug fixes.
The most notable features and changes are documented on this page. A full list of bugs that have been addressed is included further below.
Major changes and features
Switched to storhaug for ganesha and samba high availability
Notes for users:
High Availability (HA) support for NFS-Ganesha (NFS) and Samba (SMB) is managed by Storhaug. Like the old HA implementation, Storhaug uses Pacemaker and Corosync to manage Virtual (floating) IP addresses (VIPs) and fencing. See https://github.com/linux-ha-storage/storhaug.
Storhaug packages are available in Fedora and for several popular Linux distributions from https://download.gluster.org/pub/gluster/storhaug/
Note: Storhaug does not dictate which fencing solution should be used. There are many to choose from in most popular Linux distributions. Choose the one the best fits your environment and use it.
Added SELinux support for Gluster Volumes
Notes for users:
A new xlator has been introduced (
features/selinux) to allow setting the
extended attribute (
security.selinux) that is needed to support SELinux on
Gluster volumes. The current ability to enforce the SELinux policy on the
Gluster Storage servers prevents setting the extended attribute for use on the
client side. The new translator converts the client-side SELinux extended
attribute to a Gluster internal representation (the
extended attribute) to prevent problems.
This feature is intended to be the base for implementing Labelled-NFS in NFS-Ganesha and SELinux support for FUSE mounts in the Linux kernel.
Limitations: - The Linux kernel does not support mounting of FUSE filesystems with SELinux support, yet. - NFS-Ganesha does not support Labelled-NFS, yet.
Known Issues: - There has been limited testing, because other projects can not consume the functionality yet without being part of a release. So far, no problems have been observed, but this might change when other projects start to seriously use this.
Several memory leaks are fixed in gfapi during graph switches
Notes for users:
Gluster API (or gfapi), has had a few memory leak issues arising specifically during changes to volume graphs (volume topology or options). A few of these are addressed in this release, and more work towards ironing out the pending leaks are in the works across the next few releases.
Limitations: - There are still a few leaks to be addressed when graph switches occur
get-state CLI is enhanced to provide client and brick capacity related information
Notes for users:
The get-state CLI output now optionally accommodates client related information
corresponding locally running bricks as obtained from
gluster volume status <volname>|all clients. Getting the client details is a
is a relatively more costly operation and these details will only be added to
the output if the get-state command is invoked with the 'detail' option. The
following is the updated usage for the get-state command:
# gluster get-state [<daemon>] [[odir </path/to/output/dir/>] [file <filename>]] [detail]
Other than client details, capacity related information for respective local
bricks as obtained from
gluster volume status <volname>|all detail has also
been added to the get-state output.
Limitations: - Information for non-local bricks and clients connected to non-local bricks won't be available. This is a known limitation of the get-state command, since get-state command doesn't provide information on non-local bricks.
Ability to serve negative lookups from cache has been added
Notes for users:
Before creating / renaming any file, lookups (around, 5-6 when using the SMB protocol) are sent to verify if the file already exists. The negative lookup cache, serves these lookups from the cache when possible, thus increasing the create/rename performance when using SMB based access to a gluster volume.
Execute the following commands to enable negative-lookup cache:
# gluster volume set <volname> features.cache-invalidation on # gluster volume set <volname> features.cache-invalidation-timeout 600 # gluster volume set <VOLNAME> nl-cache on
Limitations - This feature is supported only for SMB access, for this release
New xlator to help developers detecting resource leaks has been added
Notes for users:
This is intended as a developer feature, and hence there is no direct user impact.
For developers, the sink xlator provides ways to help detect memory leaks in gfapi and any xlator in between the API and the sink xlator.
More details can be found in this thread on the gluster-devel lists
Feature for metadata-caching/small file performance is production ready
Notes for users:
Over the course of releases several fixes and enhancements have been made to the mdcache xlator, to improve performance of small file workloads. As a result, with this release we are announcing this feature to be production ready.
In order to improve the performance of directory operations of Gluster volumes, the maximum metadata (stat, xattr) caching time on the client side is increased to 10 minutes, without compromising on the consistency of the cache. Significant performance improvements can be achieved in the following workloads on FUSE and SMB access, by enabling metadata caching:
- Listing of directories (recursive)
- Creating files
- Deleting files
- Renaming files
To enable metadata caching execute the following commands:
# gluster volume set group metadata-cache # gluster volume set network.inode-lru-limit <n>
\<n>, is set to 50000 by default. It should be increased if the number of concurrently accessed files in the volume is very high. Increasing this number increases the memory footprint of the brick processes.
"Parallel Readdir" feature introduced in 3.10.0 is production ready
Notes for users:
This feature was introduced in 3.10 and was experimental in nature. Over the course of 3.10 minor releases and 3.11.0 release, this feature has been stabilized and is ready for use in production environments.
For further details refer: 3.10.0 release notes
Object versioning is enabled only if bitrot is enabled
Notes for users:
Object versioning was turned on by default on brick processes by the bitrot xlator. This caused, setting and looking up of additional extended attributes on the backed file system for every object, even when not actively using bitrot. This at times caused high CPU utilization on the brick processes.
To fix this, object versioning is disabled by default, and is only enabled as a part of enabling the bitrot option.
Distribute layer provides more robust transactions during directory namespace operations
Notes for users:
Distribute layer in Gluster, creates and maintains directories in all subvolumes and as a result operations involving creation/manipulation/deletion of these directories needed better transaction support to ensure consistency of the file system.
This transaction support is now implemented in the distribute layer, thus ensuring better consistency of the file system as a whole, when dealing with racing operations, operating on the same directory object.
gfapi extended readdirplus API has been added
Notes for users:
An extended readdirplus API
glfs_xreaddirplus is added to get extra
information along with readdirplus results on demand. This is useful for the
applications (like NFS-Ganesha which needs handles) to retrieve more information
along with stat in a single call, thus improving performance of work-loads
involving directory listing.
The API syntax and usage can be found in
glfs.h header file.
- This API currently has support to only return stat and handles (
for each dirent of the directory, but can be extended in the future.
Improved adoption of standard refcounting functions across the code
Notes for users:
This change does not impact users, it is an internal code cleanup activity that ensures that we ref count in a standard manner, thus avoiding unwanted bugs due to different implementations of the same.
Known Issues: - This standardization started with this release and is expected to continue across releases.
Performance improvements to rebalance have been made
Notes for users:
Both crawling and migration improvement has been done in rebalance. The crawler is optimized now to split the migration load across replica and ec nodes. Prior to this change, in case the replicating bricks are distributed over two nodes, then only one node used to do the migration. With the new optimization both the nodes divide the load among each other giving boost to migration performance. And also there have been some optimization to avoid redundant network operations (or RPC calls) in the process of migrating a file.
Further, file migration now avoids syncop framework and is managed entirely by rebalance threads giving performance boost.
Also, There is a change to throttle settings in rebalance. Earlier user could set three values to rebalance which were "lazy", "normal", "aggressive", which was not flexible enough. To overcome that we have introduced number based throttle settings. User now can set numbers which is an indication of the number of threads rebalance process will work with, thereby translating to the number of files being migrated in parallel.
Halo Replication feature in AFR has been introduced
Notes for users:
Halo Geo-replication is a feature which allows Gluster or NFS clients to write locally to their region (as defined by a latency "halo" or threshold if you like), and have their writes asynchronously propagate from their origin to the rest of the cluster. Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. To enable halo feature execute the following commands:
# gluster volume set cluster.halo-enabled yes
You may have to set the following following options to change defaults.
cluster.halo-shd-latency: The threshold below which self-heal daemons will
consider children (bricks) connected.
cluster.halo-nfsd-latency: The threshold below which NFS daemons will consider
children (bricks) connected.
cluster.halo-latency: The threshold below which all other clients will
consider children (bricks) connected.
cluster.halo-min-replicas: The minimum number of replicas which are to
be enforced regardless of latency specified in the above 3 options.
If the number of children falls below this threshold the next
best (chosen by latency) shall be swapped in.
FALLOCATE support with EC
Notes for users
Support for FALLOCATE file operation on EC volume is added with this release. EC volumes can now support basic FALLOCATE functionality.
Self-heal window-size control option for EC
Notes for users
Support to control the maximum size of read/write operation carried out during self-heal process has been added with this release. User has to tune 'disperse.self-heal-window-size' option on disperse volume to adjust the size.
- 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.
- Status of this bug can be tracked here, #1426508
- Latest series of fixes for the issue (which are present in this release as well) are not showing the previous corruption, and hence the fixes look good, but this is maintained on the watch list nevetheness.
