2.0
---
Skylable SX 2.0 brings major new functionalities, such as:
* Support for zone-based data distribution and replication (rack-awareness)
* Initial implementation of the Raft consensus algorithm to automate
cluster healing
* sxfs: a FUSE-based filesystem client to mount SX volumes as local
filesystems
* Intra-cluster communication is now handled on dedicated sockets with
reserved workers for improved reliability
* New 'aes256' filter with support for filename encryption
* Support for compacting of local storage ('sxsetup --compact')
* Many other improvements and bugfixes
1.2
---
The key features and improvements in this release include:
* Support for IPv6 clusters
* New 'manager' privilege for volumes (allows granting/revoking access to
other users)
* New global quota mechanism for volume owners ('sxacl usermod --quota')
* Support for cluster metadata ('sxadm cluster --(set|get|delete)-meta')
* Improvements to the aes256 filter; now the default mode is to set the
volume password during the first upload
* Server side support for mass deletes and renames
* Minor improvements and bugfixes
1.1
---
Skylable SX 1.1 brings many new features and improvements.
The major changes from 1.0 include:
* All tools now work with passwords instead of authentication keys by
default. The change is backward compatible: use --key to keep using
the existing key or use 'sxacl usernewkey' to generate a new key based
on a password. For security reasons, the automatically created admin
account uses a random-generated key by default.
* Faulty nodes can now be disabled without the immediate need to replace
them ('sxadm cluster --set-faulty')
* New garbage collector that improves speed of sxrm operations and supports
nodes, which are temporarily separated from the cluster.
* No new revision will be created on multi-revision volumes, if an
overwritten file hasn't changed at all.
* New tool 'sxdump' to automate cluster backup and recovery.
* 'sxsetup --upgrade' to automatically upgrade cluster databases and
storage to the latest format after updating the software.
* 'sxinit --config-link' (use a configuration link for an automated setup)
* 'sxinit --sxauthd' (use company credentials to access a cluster with SX
Enterprise Edition extensions)
* 'sxls --etag' (detect changes in volume contents)
* 'sxadm node --check' improvements (now also requires cluster to be in
read-only mode or a node to be offline)
* 'sxadm cluster --set-mode' (set cluster to read-only mode and back)
* 'sxinit --info' (display information about a configured profile)
* 'sxadm cluster --list-nodes' (list all nodes and their configuration)
* Performance improvements, including better sxls efficiency
* Other improvements and bugfixes
1.0
---
This is the first stable release of Skylable SX. The changes
from 0.9 include:
* New user manual covering all important cluster and
client operations (see doc/manual/manual.pdf or
http://www.skylable.com/products/sx/manual)
* Support for replacing and rebuilding of broken nodes (see
the manual for instructions on cluster healing)
* New tool 'sxmv' for moving and renaming files (see 'man sxmv')
* 'sxcp --ignore-errors' (ignore errors during recursive operations
and report them at the end)
* 'sxcp --exclude/--include' (skip or process files matching specific
patterns)
* 'sxvol modify' (change configuration of existing volumes)
* 'sxadm --resize' (proportionally grow or shrink the entire cluster)
* 'sxadm node --check' improvements (better detect local problems,
eg. with faulty hard drives)
* 'sxadm node --extract' (recover local storage in emergency situations)
* Many improvements and bugfixes
0.9 (Final Beta)
----------------
This is a final beta of Skylable SX! Changes in this release include:
* New garbage collector implementation, both more robust and scalable
* Full support for file revisions (see 'man sxrev' and 'man sxvol' for
details on how to manage and work with the revisions)
* "undelete" filter (see 'sxvol filter --info undelete')
* Usability improvements, including new man pages for the client tools
* Many minor improvements and bugfixes
0.4 (Fourth Beta)
-----------------
This release contains important enhancements and bugfixes, including:
* Automatic rebalance when nodes are added, modified or removed
from the cluster
* aes256 filter now uses the AES-256-CBC-HMAC-512 mode and bcrypt for
key derivation
* sxcp --one-file-system support (to not cross filesystem boundaries)
* sxcp can now limit the number of connections (global and per host), see
--full-help for usage information
* Many usability enhancements in the client tools
* Other improvements and bugfixes
0.3 (Third Beta)
----------------
The key features and improvements in this release include:
* Support for using a custom port number (configure with sxsetup --advanced).
This also allows sxsetup to run without root privileges when SX is
configured to run on a port higher than 1024.
* sxcp now displays a progress bar while transferring files
* sxcp --bwlimit support (to set a bandwidth usage limit)
* configure --with-system-libs support (to force the use of system libraries
instead of those bundled in 3rdparty/)
* Many minor improvements and bugfixes
0.2 (Second Beta)
-----------------
Changes in this release include:
* Support for building with either NSS or OpenSSL
* Minimum Curl version supported is now 7.34.0 (configure will use the
embedded version if the system's one is not supported - this allows
out-of-box build on CentOS 6)
* aes256 filter now generates per-volume salts; in order to preserve
deduplication support across different volumes using the same password
you can force a static salt, eg. --filter aes256="salt:af6a812ad0b1cb22"
* sxinit --force-reinit support (to recreate the entire local cluster config)
* sxinit --list support (to list all configured clusters and profiles)
* sxinit --alias support (to assign an alias for easy access), see
https://wiki.skylable.com/wiki/Sxinit#Aliases
* sxls -l now also lists filters used by volumes
* Other bugfixes and improvements
0.1 (First Beta)
----------------
Initial public release of Skylable SX.
