Highlights

Performance improvements for the concurrent directory creation and removal

Acknolagements

Many Thanks to Lars Jansse and Sandro Grizzo for their contributions.

Incompatibilities

prior to version 9.2 dCache NFSv4.1 door will publish only nfs4_1_files layout. Now on the door publishes all available layout types
dropped reference count tracking for directory tags
dropped support of java options chimera_soft_update and chimera_lazy_wcc in favor of chimera.attr-consistency property
If upgrading from 8.2, be sure to read also the release notes for 9.0 and 9.1, important changes are described there. See the 9.2 migration guide for more complete information
With version 9.2.8+, empty and non-existent banfiles will be treated the same

Release 9.2.18

webdav

When running multiple Remote Transfermanager, two transfer that were started simultaneously had the same ID which led to the second transfer becoming orphan after the first one completed. This is fixed now.

Release 9.2.17

common

The out-of-box version of ProxyCSRGenerator#generate from CAnL uses SHA1 for proxy delegation, which is banned by modern OSes.

this now fixed and RHEL9 clients works with proxy delegation without enabling SHA1.

xroot

Switch to xrootd4j–4.6.0, ew major release with bug fixes and enhancements including the reload TLS certificate.

Release 9.2.15

bulk

Some of the format strings that manage the formatting of command results were sending to the user expect a different number of parameters than provided. This is now fixed and the returned bulk info strings return all expected values.

info

DGAs send messages to other dCache cells to discover their current status. These messages have a hard-coded one second timeout.

Some queries are data-intensive and could take longer than one second to build the answer, resulting in no information being provided.

this is now fixed and the info service will now wait longer for a cell to respond to a query for information.

nfs

Grizzly memory management uses heap memory size fraction even if direct memory is used (issue 7529). This issue has been fixed and dCache starts with 256m of direct memory.

da22a29c73: webdav: fix slow listing
2d73d8ba98: [maven-release-plugin] prepare for next development iteration

Release 9.2.10

webdav

A recent path introduced support for adding the Link HTTP response header, according to RFC 6249. Unfortunately, the code added the Link header for all requests, not just the intended GET and HEAD requests.

Additionally, due to peculiarities of how Milton generates PROPFIND results, the Link header is added multiple times: once for each subdirectory.

This results in the HTTP response headers taking up too much space and dCache failing the request, returning a 500 status code.

This regression has been now fixed where PROPFIND requests would fail if the directory contains too many subdirectories. The cut-off point depends on the length of the URL the PROPFIND request targets.

Changelog 9.2.9..9.2.10

Changelog 9.2.8..9.2.9

ffef10d130: [maven-release-plugin] prepare release 9.2.9
c7993fe0f3: gplazma: fix NPE if gPlazma is rejecting all logins
42d497e172: [maven-release-plugin] prepare for next development iteration

Release 9.2.8

chimera

A recent commit as a side effect resulted in failure to upload a file to an xroot door with the overwrite (“-f”) option, returning okay but removing the original file without creating the new one. This patch reverts the offending commit: copy with an overwrite flag works again.

CI

Improve build pipeline.

gplazma

Previously, a missing banfile would result in every successive login attempt failing with an NPE. Now, even if configured, an empty or inexistent banfile will be ignored and logins should succeed. WARNING: This changes the banfile plugin behaviour! Empty and non-existent banfiles will be treated the same.

system-test

Increases the small default direct memory value for system-test: NFS on system-test works again.

webdav

Update webdav door to retry the request to the namespace if checksum is not present in files attributes.

xroot

A recent commit introduced handling of relative paths in xrootd with inadvertent side effect of dropping support xroot.root variable. This patch reverts that commit: pre–9.2 behavior is restored.

cleaner-disk

No more occasional ConcurrentHashMap exceptions in cleaner-disk runs due to concurrent pool status changes.

core

Admin commands with hyphen-containing arguments are no longer trunkated prematurely, they are now properly shown and autocompleted.

qos

Prevent PropertySetterException in qos.

xroot

The change to use effectiveRoot did not take into account Subject = Nobody.

Regression eliminated, previous behavior with anonymous read restored.

dependencies

The MongoDB driver was updated. This might lead to different log messages.

frontend

A bug was fixed that led to an Exception when using qos without policy.

webdav

If a non-existing well-known resource is requested, it won’t log a stacktrace anymore.

Release 9.2.5

bulk

The current releae fixed handling of uncaught exception.

dcache-view

dCache-view has been updated to 2.1.0 and it includes modifications to use new RolePrincipal instead of the roles plugin role, eliminating the need for additional logins for admin privileges.

qos

With ingest queues servicing large numbers of requests, as we have for performance reasons configured as defaults on QoS and Bulk, there was a potential for a race between the processing of the original modify request and a subsequent cancellation request, such that cancellation could not find the request as it was still in the executor queue.

This is fixed now and are is a trailing stream of requests still being processed after cancellation (from Bulk) completes.

Release 9.2.4

chimera

The rollback of 9.1 to 9.0 db schema was fixed and possibility to rollback namespace db to an earlier schema version is restored now.

webdav

The urls similar to this https://door.domain.foo:1234//pnfs/domain.foo/path/to/file were strip into /domain.foo/path/to/file.

The current release fixed the parsing of urls with two slashes in the path.

Release 9.2.2

bulk

A bug was fixed that may lead to the archiver deleting ongoing requests.

qos

The default size of the task queues are set to “qos.limits.verifier.max-running-operations” now to increase the throughput. IMPORTANT: The default size of the QoS Engine’s modify thread pool was also updated to 500 as the current value, 32, is too little.

Release 9.2.1

bulk

Correct bulk cancellation semantics.

The problem with cancellation (hanging perpetually in the CANCELLING state) was solved.

Return directory listing to its own executor.

Same performance as before, but with a total memory footprint at a little more than half available physical memory instead of being very close to it.

Add commands to display the count instead of the actual entry (as with requests and targets), and also a command to clear/delete from the archive table.

documentation

Add commands to display the count instead of the actual entry (as with requests and targets), and also a command to clear/delete from the archive table.

Fixes link in documentation.

Add section in WebDAV door chapter on metalink.

Release 9.2.0

Known issues

Cancel is currently broken in bulk service and recursive requests could freeze up.

Admin

Paging capability was added to the AnsiTerminalCommand (and DirectCommand), where results exceeding 10K lines prompt the user with [Y/N] for further results. When executing a shell command in non-terminal mode, all results are streamed back continuously. The Bulk commands have been converted to use this feature.

Bulk

There have been many small fixes and improvements to this service since 8.2.

The most significant changes or additions include:

The storage layer has been redesigned to conserve space and for efficiency/throughput. Please note that moving up to the new database schema may require some time.
The amount of time can be generally computed in terms of the number of entries in the request_target table; figure about 1 hour for every 10 million. If it is necessary to maintain all such entries, we recommend you do the upgrade offline, using the dcache database update command-line tool. If there is no need to keep completed requests in the database, we would advise truncation or at least deletion of the completed requests before the upgrade.
Periodic archiving of requests has been added; this is configurable via properties and admin commands. The archive table maintains an abbreviated summary of the requests, and can be purged via admin command as well.
The container job has been rewritten to bring it in line with SRM bringonline performance; multithreaded directory listing has also been implemented to improve recursive request time-to-completion.
Path resolution (for relative paths) has been integrated into bulk request processing.
Activity providers now can capture the environment so that defaults can be customized (this presently pertains only to pin and stage lifetime attributes).
Support has been added for the QoS update request to handle policy arguments.
Bulk has been made replicable (HA). Please read the requirements in the cookbook section on High Availability.
The delay clear option has been eliminated from bulk requests.
The prestore option has also been eliminated, as it is no longer necessary (since all initial targets are immediately batch stored synchronously) before the submission request returns.

A few minor points:

Default limits for request size and number of requests per user have been set on the basis of WLCG requirements.
The counts displayed by the info command are from startup and are cumulative; for actual (current) counts based on the data store, use the status counts command.

There are numerous properties which have been deprecated, particularly those dealing with limits. Please review the bulk.properties file for details. It should not be necessary under normal usage to adjust the limits for thread pools, database connections and semaphores from the defaults. Depending on the volume of activity and the site requirements, the archiver period and window may need to be shortened from the default. Note that the options for clearOnSuccess and clearOnFailure that can be included in an individual bulk request to indicate immediate deletion are not available for STAGE requests as this feature is not part of the WLCG specification, so the only way to remove such requests automatically is through the archiver.

Chimera

With dcache version 9.0 chimera has introduced chimera_soft_update and chimera_lazy_wcc Java properties to control the behavior of the parent directory attribute update policy. Now those properties are obsolete and replaced by a regular dcache configuration property chimera.attr-consistency, which takes the following values:

policy	behaviour
strong	a creation of a filesystem object will right away update parent directory’s mtime, ctime, nlink and generation attributes
weak	a creation of a filesystem object will eventually update (after 30 seconds) parent directory’s mtime, ctime, nlink and generation attributes. Multiple concurrent modifications to a directory are aggregated into a single attribute update.
soft	same as weak, however, reading of directory attributes will take into account pending attribute updates.

Read-write exported NFS doors SHOULD run with strong consistency or soft consistency to maintain POSIX compliance. Read-only NFS doors might run with weak consistency if non-up-to-date directory attributes can be tolerated, for example, when accessing existing data, or soft consistency, if up-to-date information is desired, typically when seeking newly arrived files through other doors.

Frontend

Aside from bug fixes, the following changes should be noted:

Support for .well-known/security.txt was added to both the frontend and WebDav ports.
More detailed description of request objects for bulk and stage.
Improved error messages in several places.
Support for relative paths and symlink prefix resolution for bulk and namespace resources.
The frontend.wellknown paths have been deprecated in favor of dcache.wellknown.
Authz checks have been removed in Quota GET methods.
Use of RolePrincipal (see under gPlazma) replaces reliance on LoginAttributes and the old admin role (special gid) as defined by the roles plugin.
Support for QoS Rule Engine policies. A new qos-policy resource allows one to add, remove, list and retrieve policy definitions. See the Swagger pages for details.
An -optional query parameter was added to the namespace resource to retrieve extra information about a file; the new QoS Policy file attributes (QOS_POLICY and QOS_STATE) are included with this option.
Support for pool migration has been introduced (migrations resource). See Swagger pages for details.

gplazma

A RolePrincipal has been added to support the use of role definitions in the multimap file. Currently the available roles are: admin, qos-user and qos-group. The second allows the user to transition files owned by the user’s uid; the third allows the user to transition files whose group is the user’s primary gid. The two qos roles can be combined. Admin grants full admin privileges. A multimap example:

dn:"/DC=org/DC=cilogon/C=US/O=Fermi National Accelerator Laboratory/OU=People/CN=Al Rossi/CN=UID:arossi" username:arossi  uid:8773  gid:1530,true roles:admin

These roles do not depend on the presence of the roles plugin. Since the frontend has been changed to use the new RolePrincipal and not the old role definitions (where a special gid must be defined), one can easily drop that plugin from the gplamza.conf file.

There was also an important fix for a bug that was preventing upload (e.g., xroot POSC) when using tokens.

The gplazma-xacml plugin has been dropped.

NFS

Prior to version 9.2 dCache, to support RHEL6 based clients, if no species export options are specified, the NFSv4.1 door were publishing only nfs4_1_files layout. Now on the door publishes all available layout types. If for whatever reason RHEL6 clients are still used, the old behavior can be enforced by lt=nfsv4_1_files export option.

PNFS Manager

To remove unused directory tags chimera keeps the reference count (nlink) of tags. This approach creates a ‘hot’ record that serializes all updates to a given top-level tag. Starting 9.2 dCache doesn’t rely on ref count anymore and uses conditional DELETE, which should improve the concurrent directory creation/deletion rate.

Pool

The mover ls command is updated to display with the -u option the subject associated with the mover.

Added pool.mover.https.port.min and pool.mover.https.port.max to control TPC port number used by HTTPS mover.

Pools info command displays HTTP, HTTPS, NFS and XROOT movers listen ports and interface.

Billing information from DCAP and FTP movers now on include local socket end point

Poolmanager

Pnfsid and path options have been added to ac psu match.

Re-introduce wrandom partition type - a weighted-random pool selection partition, which works as a WASS partition, but ignores LRU metric and number of movers.

QoS

Aside from bug fixes, the following significant changes to QoS should be noted:

QoS was made to support migration using a new pool mode, “DRAINING”; please consult the book chapter for further details.
The DB namespace endpoint can now be configured to be separate from the main Chimera database (originally introduced/changed for Resilience). In this way, the scanner, whose namespace queries are read-only, could be pointed at a database replica.

This remains possible for QoS, even though the QoSEngine now also is responsible for updating Chimera with file policy state. These writes are all done via messaging (PnfsHandler) rather than by direct DB connection, so they go to the master Chimera instance.
Requests for QoS transitions are now authorized on the basis of role (see under gPlazma).
The first version of the QoS Rule Engine has been added. With this, one can define a QoS policy to apply to files either through a directory tag or via a requested transition; the engine tracks the necessary changes in state over time. A new database table has been added to the qos database. Remember that if you are deploying QoS for the first time, you need to create the database:

createdb -U <user> qos

Fuller explanation of the rule/policy engine is forthcoming in the Book chapter.
In conformity with the new rule engine changes, the scanner has been modified in terms of how it runs scans. There are now two types of system scans, the (NEARLINE) QoS scans (to ensure that files with a policy requiring them to be flushed have indeed been written to tape) and a system-wide ONLINE scan (there are two versions of this and an option to choose which one). Details in the Book; also refer to the relevant admin commands.

Note that the singleton QoS service (where all four components are plugged into each other directly) is no longer available; the four services can, however, still be run together or in separate domains, as with any dCache cell.

Resilience

Resilience is still available in 9.2, but should be considered as superseded by the QoS services. We encourage you to switch to the latter as soon as is feasible. Remember not to run Resilience and QoS simultaneously.

A recipe has been added to the cookbook for migration/draining of resilient pools. This continues to apply in QoS.

WebDAV

The WebDAV door now provides limited support for metalink format. Metalink is an XML format, described by RFC 5854, that describes how to download multiple files. The initial support is limited to describing the files within the targeted directory: there is no support for recursion. The metalink information is available via HTTP Content Negotiation (client sends a Accept: application/metalink4+xml header) or via a Link HTTP response header (see RFC 6249) when generating the normal HTML output.

XRootD

Aside from bug fixes and various documentation additions and clarifications, the following should be noted:

Proxying through the xroot door is now available.
Relative paths are supported in the xroot URL.
Resolution of symlinks in path prefixes and paths is supported.
The efficiency of the stat list (ls -l) has been greatly improved.

An Xroot User Guide page has been started.
