Arvados 2.3.0 Release Notes
October 27, 2021
The Arvados team is pleased to announce Arvados 2.3.0. This is a major upgrade, with many new features as well as bugfixes. We recommend that new and existing installations of 2.2.2 or earlier upgrade to 2.3.0. See Upgrading Arvados for upgrade instructions.
Initial LSF support
This new release adds support for dispatching containers to Spectrum LSF clusters, allowing the integration of Arvados to additional HPC environments.
For more information please check our documentation page.
Initial Singularity support
This major release adds initial support for running containers with the Singularity Runtime.
We’ve tested this version against Singularity 3.7.4. For more information please check the documentation.
Improved Storage Classes support
This release features expanded support for storage classes. Storage classes enable clients to control which storage backend volumes are used to store data associated with each collection. This makes it possible to manage heterogenous storage with different performance/price/capacity/robustness characteristics.
Arvados applications now support uploading data directly to specific storage classes. This is described in the the user guide. If a storage class is not specified, it will use the default storage classes assigned by the administrator.
Keepstore services now parallelize data write operations when a data block is assigned to multiple storage classes. The administrator can also prioritize which storage classes are preferred for read operations. Please refer to the admin documentation for more information.
Workbench2 now integrates the browser-based shell node access on its own instead of redirecting to the older Workbench1. This includes support for session auto-logout.
Workbench2 collection’s file browser
The new collection file browser allows navigating through more significant collections faster by loading partial file listings on demand instead of requesting the entire collection at once. This is most noticeable on collections with many directories and/or files.
Group-sync tool improvements
This release’s group syncing tool
arvados-sync-groups allows case insensitive
username matching as described on the admin guide.
Collection manifest handling
Collection manifest signing performance and caching are notably improved. This will be most noticeable when dealing with really big data collections.
The pagination display now works correctly when showing empty tables.
Upload speed indication is now fixed showing
MB/s instead of
Data access fixes
WebDAV caching fix improves performance on huge collections. Fixed occasional mount point deadlock bugs in the PySDK FUSE driver (arv-mount).
Deprecated database indexes
Removed deprecated full text search database indexes. These were unused and sometimes interfered with creating collections with very large numbers of files and directories.
Error reporting fixes
Request-ID propagation fixes improve error traceability and debugging. Keepproxy spurious 413 error fix avoids future debugging confusion.
Python SDK fixes
Fixed the socket read timeout issues on collection create calls.
python-rsa dependency to address the security advisory CVE-2020-13757.
google-api-python-client dependencies that were
causing issues to some users.
Cached user records handling in a satellite cluster auto-resolves
Fixed container locking issue & improved logging on dispatcher.
