qos

A bug was fixed that let to the message queue being blocked.

webdav

This patch speeds up listing of directories through webdav. All attributes are no longer supported/returned from PROPFIND, unless you set the following property on the WebDav door:

#  --- Default PROPFIND properties
#
#  The PROPFIND request allows a client to discover information
#  (properties) of dCache content.  When making a PROPFIND request,
#  the client normally indicates which properties are of interest.  If
#  not specified then the WebDAV server (dCache) is free to return a
#  default set of information.
#
#  Certain clients make PROPFIND requests without specifying
#  the desired set of properties, triggering a default set of
#  properties.  There are two problems with this: first, the
#  clients may react badly if information is missing from this default;
#  second, some of the required properties may have an adverse
#  performance impact for dCache.
#
#  This property controls whether to support client-side requests for
#  properties beyond a minimal set or not.
#
#      PERFORMANCE -- always return only a minimal set of information that does
#                     not incur any additional overhead. (These are basically
#                     the same as what a POSIX list request would proviode).
#
#      CLIENT_COMPATIBLE -- return the set of information required by
#                     the clients.  If the client does not specify the properties,
#                     it will get a maximal default set.
#
#  Because the performance impact of the latter under the most common usage scenarios
#  could be considerable, the default is set to PERFORMANCE.
#
(one-of?PERFORMANCE|CLIENT_COMPATIBLE)webdav.default-propfind-properties = PERFORMANCE

Release 9.0.13

dcache-bulk

Changes were recently made to hold statistical counts of requests and targets in memory for the sake of efficiency. However, running target counts are still problematic. This is especially true if a request is cancelled.

This is now fixed and the running count, which can be confusing and inaccurate, is not longer displayed.

RT 10496: Odd errors in Bulk logs for some requests in 9.1.0

This ticket uncovered a bug in the abort procedure.

The stored targets were not cancelled on abort. this is now fixed.

dcache-xroot

Improve efficiency of stat list (ls -l) has been introduced.

ls -l returns in approximately the same amount of time as a non-stat listing ls.

xrootd4j

Upgraded to 4.5.8 which improves handling/logging of Ssl exceptions.

Release 9.0.12

pnfsmanager

List scheduling behavior is now optional.

pnfsmanager.enable.parallel-listing property variable allows to restore previous behavior - listing requests are dispatched to a single queue that is prrocessed by multiple parallel workers.

dCache admin can change behavior of listing scheduler.

This is now fixed.

qos

A bug in storing and retrieving tried value for verify operation has been fixed.

2db0433ac9: [maven-release-plugin] prepare for next development iteration

Release 9.0.9

frontend

If the user root contains a symlink, or the target path contains a symlink pertaining to the user root, some REST calls to /api/v1/namespace and /api/v1/id failed. This is fixed now.

All of the REST GET methods now allow anonymous users to get the data if the global property allows it. In the case of NONE, 401 not authorized is returned at login.

nfs

A race condition was fixed that let to sending a READ request to a pool when the mover was alreay stopped.

qos

The behaviour was changed to not scan all pools on startup or periodic rescanning of all pools outside the periodic window.

A bug was fixed that prevented the bulk request to complete.

The error reporting of aborted verification was improved to get a better understanding, what went wrong.

xrootd

A missing vomsdir is now throwing an exception instead of a stacktrace.

xrootd4j

Update xrootd4j to a new version, that fixes a byte buffer leak in ZTNCredentialUtils.

Double counting of RUNNING targets has been fixed.

dcache

netty library has been updated to 4.1.92 with minor bugfix release.

frontend

SWAGGER comments for bulk offset on POST and GET has been updated.

metadata

No user- or admin observable changes.

pnfsmanager

Multiple batch jobs executing listings of the same directories especially if directories contain many entries quickly exhaust active threads, each thread executing the same listing, denying listing to all other customers and creating significant load on namespace server (and DB). Clients time out and retry creating even more load on dCache.

This is now fixed and lists of large directories no longer hog PnfsManage denying service to all other list calls. Additionally observed significnat reduction of CPU and IO load on chimera DB host.

Release 9.0.5

dcache

Symlinks on both constraints and targets are permitted; thus macaroons will also work.

The support for both absolute and relative paths does not fail if there are symlinks affecting the path prefix.

gplazma

If there is a login failure involving a OIDC JWT then potentially important information is now extracted from the JWT and included in the logged login failure report.

POSC works with tokens when user root is ‘/’.

kafka

Change the LoggingProducerListener so that when a TimeoutException is caught, the error message will indicate that there is a connection issue or the broker is down.

nfs

When on LAYOUTGET door returned an error back to the client, then, as the operation failed, the client will not issue LAYOUT_RETURN. Thus such transfers would stay in the door. This is now fixed.

Release 9.0.3

bulk

QoS properties have been set to default to WLCG values. Also decreased the number of targets in a shallow request and increased number of threads available for target activities to 200.

Correct paths for recursively found targets are returned; i.e., absolute if the user submitted absolute paths, relative is the user used relative paths on the initial targets.

qos

Proper handling of the QoSModify requests: propagate the subject downstream to the actual adjustment tasks.

webdav

Correct behaviour on redirect with prefix.

Better error message reporting.

The RESTful interface supports paths relative to the user root as well as absolute paths for requests to the bulk service.

Note: a separate solution will be necessary for the one-off namespace resource operations.

kafka

Ensure, that exception is converted to a string. Better logging.

migration

When broken files were discovered during migration the migration module was going into sleeping state. This is now fixed.

pnfsmanger

The current release fixed migration move/copy going into SLEEP mode when the file on the pool has been deleted.

pool

Now the reduce possibility of stacked movers in CANCELED state is ensured.

Release 9.0.0

Admin

Paging capability has been added to certain admin commands. This means that large lists of results that exceed a certain limit are returned in chunks <= to the limit, and the user is prompted as to whether more should be displayed [Y/N]. These commands (see, for instance, bulk’s target ls), when invoked via a non-terminal script, will continue automatically to stream chunks back until the end of the list.

bulk

[41a9e807d7] dcache-bulk: fix missing pnfsid on cancel of PIN/STAGE

The move to a revised (version 2) bulk service was made with 8.2, but since then there have been a number of optimizations and improvements some, but not all, of which were backported to 8.2.

NOTE: Most importantly, there was a significant refactoring of the database tables to provide for more efficient use of space (via normalization). To preserve existing data, several somewhat costly queries are thus run on restart after upgrade from 8.2 to 9.0. As a benchmark for the amount of downtime necessary for the upgrade, figure approximately one hour per every 20M rows in the request_target table. It is always possible, in order to avoid overly long downtime delays, is to eliminate all requests which have completed; in the postgres interpreter:

DELETE FROM bulk_requests WHERE status='COMPLETED';

An important bug fix which was included in 8.2 was to change the behavior of the initial submit to store explicit targets (not those found recursively, but specified in the target list of the request) immediately/synchronously. This was needed to support WLCG requirements.

We have dropped the ‘delay’ option for request clearing for generic bulk requests. The admin command for STAGE activities now also automatically sets prestore to true, as with the request submitted through the REST API.

The admin commands for request ls and target ls now use the new paging capability.

LINK types are now handled correctly when the paths are refetched from prestored targets.

The bulk request target list JSON was fixed to be backward compatible with 7.2 (it now accepts both a string and a JSON array).

The target-by-target error reporting in the bulk request GET response JSON object is now less confusing.

Cells

The expereimantal message encoding format is removed. As a result, the property dcache.broker.channel.msg-payload-serializer is immutable and set to value standard.

Cleaner

The cleaner service, originally a single cell, now consists of two parts: one cell for disk cleaning (cleaner-disk), one for hsm cleaning (cleaner-hsm). They can be deployed as desired, be assigned different resources and each run in HA mode. This will hopefully improve performance issues and help admins configure and understand cleaner behaviour.

Be aware that the property names have changed their prefixes from cleaner.<something> to cleaner-disk.<something> and cleaner-hsm.<something>, while some admin commands have lost the “hsm” String from their name. Note: As not all previously existing parameters were used to control the behaviour of both the disk and hsm parts of the old, combined cleaner cell, please check which parameters are carried over to cleaner-hsm and cleaner-disk, respectively.

Example setup:

[dCacheDomain]
[dCacheDomain/cleaner-disk]
cleaner-disk.cell.name=cleaner-disk1

[dCacheDomain/cleaner-disk]
cleaner-disk.cell.name=cleaner-disk2

[dCacheDomain/cleaner-hsm]

Also, an admin command was added to the hsm-cleaner cell that allows forgetting a tape-resident pnfsid, meaning removing any corresponding delete target entries from the cleaner’s trash table database.

Core

To reduce network-configuration-based issues, starting with version 9.0, dCache does not publish IPv6 link-local or locahost IP addresses in the login broker. However, the connections for those interfaces are acepted.

DCAP

The DCAP door will fail the request if a file’s storage unit is not configured at the PoolManager, as all other doors already do.

Since dCache 1.7.0 the DCAP door was supporting two modes of establishing data connection between a client and a pool. Either a pool is connected to the client, or the client initiates the connection to a pool. The latter is a firewall-friendly behavior, but should be requested by the client. Starting with dCache 9.0, the DCAP movers will always start in a passive mode, independent of client preference.

Frontend

There have been several bug fixes to the frontend bulk API, particularly to make it backward compatible with 7.2 and to fix regressions in the new /api/v1/stage resource. A bug blocking STAGE submissions where fileLifetime was not specified has been fixed.

A bug with mv (rename) and relative paths in the /api/v1/namespace resource was corrected.

Support was added for .well-known/security.txt, exposed both on the frontend and webdav ports.

Support for maintaining the pre–8.2 implementation for /api/v1/namespace qos transitions (via a dcache property) was added; also, if this is not set to false and the QosEngine service is not running, the namespace qos transition will now fail fast.

The default type parameter to ``/api/v1/pools/{pool}/nearline/queues (=all types) now works.

It is now possible to filter and sort the results of the /api/v1/restores by path, owner and group. Since this, as with other RESTful commands, is implemented as a string ‘contains’, it is possible to match all restore activity for a directory.

The User Guide has been updated to reflect the correct WLCG URL prefix and to add more information concerning support for .well-known.

gplazma

Upload (as in xrootd’s -P / persist on successful close) permissions with JWT token claims now work correctly.

History

A bug handling NaN (not a number) errors in histogram conversion has been fixed, as well as one for index-out-of-bounds errors in timeseries histograms.

NFS

The NFS door will fail the request if a file’s storage unit is not configured in PoolManager, as all other doors already do. The new show open files command lists all open files whether or not a mover exists for them (the latter is displayed by show transfers).

Pool

Typically, when dCache interacts with an HSM, there is a timeout on how long such requests can stay in the HSM queue. Despite the fact that those timeouts are HSM-specific, dCache comes with its own default values, which are usually incorrect, so admins usually end up explicitly setting them.

Starting with version 9.0, the default timeout has been removed. This means that there is no timeout for HSM operations unless explicitly set by admins.

NOTE: this change is unlikely to break existing setups, as previous timeout values are already stored in the pools setup file.

In addtion, a new command sh|rh|rm unset timeout has been added to drop defined timeouts.

QoS Engine

Some regressions which occurred during the adaptation of resilience code have been fixed; these involved the monitoring of pool status changes and support for regex resolution in the poolmanager configuration.

Support for migration using a new pool mode, “DRAINING”, was added. As with Resilience, a separately configurable namespace endpoint is now possible.

Resilience

Now allows for a separately configurable namespace endpoint (for instance, if resilience were to use an RDBMs replica instance rather than the live instance of chimera).

A recipe for the migration/draining of resilient pools has been added to the dCache cookbook.

XRootD

There have been a number of bug fixes since 8.2.0. These have all been backported. They involve handling of the door address and proper shutdown on error for the door proxy, returning the correct error code when a file exists, making the handling of anonymous restrictions by the door consistent (for multiple authentication protocol doors), correct handling of error logging, and not publishing link local addresses.

Defaults have been changed for number of mover threads (now uses Netty defaults) and the order of the door’s gplazma plugins (ztn before gsi).

Improvements to documentation concerning TLS and host cert/key, recommendations for direct memory usage with door proxy; we have also added an Xroot User Guide page (only minimally populated at the moment).
