glite-SE_dcache_admin_postgres - Update to version 3.0.4-0

Date 20.06.07
Priority Normal


dCache update

IMPORTANT NOTE: It is recommended that both client and server are updated at the same time. Otherwise following kind of problems may occur:

If sites run dCap doors within their dCache service and don't synchronize the upgrade of the client and the server then SRM transfers using the dCap protocol may suffer. The dCache client srmcp, from the older dCache client rpms will use dCap as the default transfer protocol with the new server. If sites are using dCap they should already know that dCap is rsh-like with respect to authentication. The implication is that users files will be written with the UID the client who initiated the transfer (root is blocked). This can cause issues when users have different UID's on the client from the UID they are mapped to on the server via the gridmap file. This will only happen when dCap as a running dCache door. The implications of using dCap transfers writing to one UID and gsiftp writing to another UID is unlikely at most sites as most sites do not have this complexity, but if this is the case sites will find that some data transfers initiated with srmcp will fail due to PNFS permissions as PNFS is UNIX like in its file system permissions. Some sites may have enabled dCap only as a read protocol, in this case all data transfers to dcache will fail when started with srmcp without specifying the preferred data transfer protocol.

Update details
  • Client now sends by default for srm get and put operations, protocols in a different priority order. The order has changed from {http,dcap,gsiftp} to {gsiftp,dcap,http}.
  • Staging bug fix. The initial state of the pin was set to PINNED for previous releases, this prevented files being staged, as the PIN manager believed the files where on disk, this has been resolved.
  • Access two different accounts with the same kerberos ticket or x509 cert now supported.
  • dCap door can now be run in the read only mode.
  • Bug fixes to the resilience manger so that 0 byte files will not replicate in an uncontrolled way.
YAIM update

The new DPM info provider is configured. YAIM introduces two new variables:
The first is the mysql DB user which gets select grant to query the database, and the second its password. Both of them are compulsory parameters. IMPORTANT: The variables should not contain any special characters (ex:'-').

The new infoprovider is called by the edguser, and, in order to have the permission, the host certificate gets installed in its .globus directory.
d-cache-lcg update

The new version (d-cache-lcg-6.2.0) provides the following improvements:
  • Ensure sgm and prd pool accounts also use the first regular pool account of their VO (fixes problem reported on LCG-Rollout list).
  • Besides "001" allow the first pool account to end in "01" for small or "0001" for large VOs.
  • Handle observed e-mail address attribute name conversion to "EMAILADDRESS" and also allow for "emailAddress" (OpenSSL 0.9.7 and later).

Please also have a look at the list of known issues.
