This feature provides a coherent -mechanism to present heal status,information and the logs associated. -This makes the end user more aware of healing status and provides statistics. - -### File_Snapshot - -This feature provides ability to take snapshots of files in GlusterFS. -File snapshot is supported on the files of QCOW2/QED format. - -This feature adds better integration with Openstack Cinder, and -in general ability to take snapshots of files (typically VM images) - -For more information refer [here] -(http://www.gluster.org/community/documentation/index.php/Features/File_Snapshot). - -### gfid-access - -This feature add a new translator which is designed to provide direct access -to files in glusterfs using its GFID - -For more information refer [here] -(http://www.gluster.org/community/documentation/index.php/Features/gfid-access). - -### Prevent NFS restart on Volume change -Earlier any volume change (volume option, volume start, volume stop, volume -delete,brick add, etc) required restarting NFS server. - -With this feature, it is no longer required to restart NFS server, thereby -providing better usability with no disrupts in NFS connections - -### Features/Quota_Scalability - -This feature provides support upto 65536 quota configurations per volume. - -### readdir_ahead - -This feature provides read-ahead support for directories to improve sequential -directory read performance. - -### zerofill - -zerofill feature allows creation of pre-allocated and zeroed-out files on -GlusterFS volumes by offloading the zeroing part to server and/or storage -(storage offloads use SCSI WRITESAME), thereby achieves quick creation of - pre-allocated and zeroed-out VM disk image by using server/storage off-loads. - -For more information refer [here] -(http://www.gluster.org/community/documentation/index.php/Features/zerofill). - -### Brick_Failure_Detection - -This feature attempts to identify storage/file system failures and disable -the failed brick without disrupting the rest of the NODE operation. - -This adds a health-checker that periodically checks the status of the -filesystem (implies checking of functional storage-hardware). - -For more information refer [here] -(http://www.gluster.org/community/documentation/index.php/Features/Brick_Failure_Detection). - -### Changelog based distributed geo-replication - -New improved geo-replication which makes use of all the nodes in the master volume. -Unlike previous version of geo-replication where all changes were detected and synced -on a single node in master volume, now each node of master volume participates in the -geo-replication. - -Change Detection - Now geo-rep makes use of changelog xlator to detect the set of files -which needs to be synced. Changelog xlator runs per brick and when enabled, records -each fops which modifies the files. geo-rep consumes these journal created by this -xlator and syncs the files identified as 'changed' to slave. - -Distributed nature - Each of the nodes take the repsonsibility of syncing the data -which is present in that node. In case of replicated volume, one of them will be -'Active'ly syncing the data, while the other one is 'Passive'. - -Syncing Method - Apart from the using rsync as the syncing method, now there tar+ssh -syncing method, which can be leveraged by the workload where there is large amount -of smallfiles. - -### Improved block device translator - -This feature provides a translator to use logical volumes to store VM images -and expose them as files to QEMU/KVM. - -The Volume group is represented as directory and logical volumes as files. - -### Remove brick CLI Change - -remove-brick CLI earlier used to remove the brick forcefully ( without data migration ), -when called without any arguments. This mode of 'remove-brick' cli, without any -arguments has been deprecated. - -### Experimental Features - -The following features are experimental with this release: - -- RDMA-connection manager (RDMA-CM). -- support for NUFA translator. -- disk-encryption -- On-Wire Compression + Decompression [CDC] - -## Minor Improvements: - -- Old graphs are cleaned up by FUSE clients - -- New command "volume status tasks" introduced to track asynchronous tasks like rebalance and remove-brick - -- glfs_readdir(), glfs_readdirplus(), glfs_fallocate(), glfs_discard() APIs support added in libgfapi - -- Per client RPC throttling added in rpc server - -- Communication between cli and glusterd happens over unix domain socket - -- Information on connected NFS clients is persistent across NFS restarts. - -- Hardlink creation failures with SMB addressed - -- Non-local clients function with nufa volumes - -- Configurable option added to mount.glusterfs to use kernel-readdirp with fuse client - -- AUTH support for exported nfs sub-directories added - - -### Known Issues: -- The following configuration changes are necessary for qemu and samba - integration with libgfapi to work seamlessly: - - 1) gluster volume set <volname> server.allow-insecure on - - 2) Edit /etc/glusterfs/glusterd.vol to contain this line: - option rpc-auth-allow-insecure on - Post 1), restarting the volume would be necessary. - Post 2), restarting glusterd would be necessary. - -- RDMA connection manager needs IPoIB for connection establishment.
