dCache server v. 2.6.17 and dCache srmclient v. 2.2.22
Affected services
- affected service: dCache server, UI, WN
What's new:
- dCache server, v. 2.6.17
- There are two issues that this release fixes with dCache's NFS v3 implementation. It is safe to upgrade dCache with mounted client machines.
- The underlying problem is due to the finite size NFS v3 provides for representing a file and how the tag dot-commands are represented. Before, the NFS v3 limit was reached for tag names longer than 7 characters: sGroup worked, but OSMTemplatefailed. With this version of dCache, the limit is pushed back to tags longer than 28 characters. This is sufficient for the tags that dCache understands.
- The upgrade from jGlobus 1.8 to 2.0 introduced a performance regression: the last-modified time of CA-related files are checked for each request, which, when these files are stored on a shared filesystem, introduces unacceptable latency. This release uses an updated jGlobus that throttles how often it checks the last-modified attribute of files.
- The transfermanager, replicamanager and the admin p2p commands rely on the same underlying pool-to-pool transfer mechanism that moves files when hot files are detected or to satisfy user read requests; however, currently they are unable to initiate such transfers. This release of dCache fixes the problem.
- The migration move and migration cache commands are mistakenly shown as migration copy commands in the output of migration ls, migration info and when saved to the setup file. This release fixes that.
- For more details see dCache server 2.6.17 - Extended Release Notes
- dCache srmclient, v. 2.2.22
- The SRM Client 2.2.22 follows the FHS compliant directory layout.
- Changes:
- Migration to jglobus2.0: SRM client now supports secure hash algorithm SHA-2 and therefore SHA-2 signed certificates. jGlobus2.0 also supports SHA-1 signed certificates. Please be aware that VOs are encouraged not to issue SHA-1 certificates any longer. Migrating to this version of SRM Client is therefore recommended.
- Switch to jglobus with jumbo proxies support. There was a problem with growing proxies which would at some point cause problems with SRM. This fix solves the jumbo proxy issue.
- For more details see dCache srmclient 2.2.22 - Extended Release Notes
Installation & Configuration
- Please notice that due to the change to jpnfs-0.0.5, all NFS clients (v3 and v4) have to unmount prior update.
- Please read the preliminary version of the Ultimate Golden Release Upgrade Guide carefully.
- for the dCache srmclient an "yum update" should update to the latest version

GridSite, v. 2.2.0
Affected Services
- affected services: CREAM, DPM, FTS, L&B, WMS, UI, WN
What's new:
- This is a minor release of GridSite addressing the issue of key lengths being hard-coded at 512 bits. It inclreases the default key length to 1024 bits, and exposes new functions in the API to accepts custom key lengths.
- For more details see Extended Release Notes
Installation & Configuration
- To deploy, update your installation and restart the Web-server.
Known issues:
- When upgrading from the EMI repository on Debian, mod_gridsite is not correctly replaced. Uninstall the old module first and install the new one to work around the issue.
Artifacts
L&B, v. 4.0.12
Affected Services
- affected services: L&B, WMS, UI, WN
What's new:
- This maintenance release of L&B provides fixes for packaging issues identified during reviews, fixes several rare memory handling issues, sets up permissions for integration with CREAM, and improves the reliability of the Site Notification Keeper.
- For more details & Known Issues please read the Extended Release Notes
Installation & Configuration:
- The emi-lb metapackage is installed by yum.
- Configuration requires, at the very least, setting MYSQL_PASSWORD, SITE_NAME and SITE_EMAIL in the site-info.def file.
- Reconfiguration is required if you are updating. On Scientific Linux, you can (re)configure by YAIM.
- On Debian, use the glite-lb-setup command. Upgrading from previous versions of L&B (earlier than 4.0) involves a database schema change. A DB migration script is available. In typical scenarios it will be initiated automatically during reconfiguration. Follow documentation in case it needs to be started manually.
