dCache ReleasesRSS

A time-line of past dCache releases and anticipated future dCache series (Large version).

Release Policy

dCache follows a time-boxed two dimensional release policy. Every three months we produce a feature release. Feature releases have version numbers 2.x.0, where x is a positive integer. Each feature release is followed up by a number of maintenance releases containing bug fixes or high priority feature tweaks. Maintenance releases for release 2.x.0 have version numbers 2.x.y, for y being an integer larger than 0. For example; 2.9.0 is a feature release, 2.9.1 is the first maintenance release for the 2.9-series and 2.9.2 is the second maintenance release.

Support period

Typically once a year, we make one feature release a long-term supported release (a "Golden Releases"). The only difference between long-term ("Golden") releases and other releases is the support period. A golden release is supported until the second subsequent long-term release, which is typically two years. Other releases are supported until the end of the previous golden release support period.

Choosing between golden releases and regular releases is a matter of site policy and a matter of taste. Newer releases contain newer features, but non-Golden releases have shorter support periods and often fewer sites using them.

Some sites use dCache that is repackaged by another distribution. Such distribution may recommend a specific version. Sites should follow their distribution's recommended version.

The support periods are shown in the time-line above. Click on the image for a larger view of the image.

Upgrading and compatibility

We support sites upgrading releases either to the next golden release or to a regular release without skipping a golden release. Upgrading in a bigger jump may be possible, but sites should take extra care as configuration may have changed in a non-backwards-compatible fashion. If in doubt, contact dCache support for help.

For the purposes of describing compatibility, we call those computers in a dCache cluster that host only one or more pool services "pool nodes" and all other computers in the cluster "non-pool nodes".

All non-pool nodes must run dCache from the same feature release but, unless indicated differently in the release notes, individual nodes may run any maintenance release from the same feature release (e.g., dCache version 2.x.y is compatible with version 2.x.z). In general, we advise sites to run the most recent maintenance release from their deployed series, but understand upgrading dCache impacts the running service.

The pool nodes do not need to run the same feature release as the non-pool nodes; they also do not need to run the same feature release as each other. Pool nodes must run either the same version or an earlier version as the non-pool nodes and the version must not be earlier than the previous golden release.

For example, if a dCache cluster has non-pool nodes running v2.8.2 then the cluster may simultaneously contain pool nodes with dCache v2.8.5, v2.7.3 and v2.6.20. The cluster may not contain pools v2.5.x as this is an earlier release than the previous golden release (2.6). The cluster may not contain pools running v2.9.0 as this is newer than the non-pool nodes.

The effect of this policy is that a site may upgrade just the non-pool nodes to a newer version without upgrading the pool nodes, provided no golden release is skipped. However, once the non-pool nodes are upgraded to a golden release, the pools must also be upgraded to that golden release.

The release notes for each release includes a compatibility matrix that describes this is further detail.

While we try to avoid configuration and schema changes in maintenance releases, moving from one feature release to another often requires some configuration changes. These are described in the release notes.

To simplify sites upgrading between golden releases, we provide upgrade guides targeted at sites jumping from one golden release to the next: 1.9.12 to 2.2, 2.2 to 2.6).

In addition to the usual improvements and bug fixes, dCache 2.6 focuses on:

If you upgrade from dCache 2.2 to dCache 2.6, please read the preliminary version of the Ultimate Golden Release Upgrade Guide carefully.

dCache 2.6 requires Java-7.

Sites upgrading to 2.6.x and runnig postgresql < 9.2 should be aware that due to an unfortunate behaviour of postgresql the automated database schema migration which is applied on startup of dCache may take a lot of time (e.g. 3 hours for 20 million files).
