The Pnfs Version 3.1.3 Patchlevel A


News


Level Attribute behaviour now tunable

With patch level 3.1.3A pnfs allows to specify the behaviour of level 1 to 7 on the creation of a file and on the modification of its attributes. Usually the levels behave as needed at DESY, which means, level 1, 2 and 7 are in sync with the top level and the residual levels remain unchanged on chmod or chown ... commands.
With Patch 3.1.3.A a new /usr/etc/pnfsSetup variable has been added which defines which level keeps in sync with the top level and which levels remain unchanged.
Syntax :     levelmask=0:x:x:x:x:x:x:x
             
             x :  -1   in sync with top level
                   0   uid=0;gid=0;mode=700

Bug fix : setattr

There was a bug which disallowed a user, who changed the mode bits of a file or directory to 000, to change it back afterwards. This problem has been removed.

Bug fix : rmdir

The attempt to remove a directory which was not yet empty removed all tags assigned with this directory. This problem has been solved.

Bug fix : mdb show

The database lookup program mdb show got confused whenever a new database name extends the name of an already used one. This problem has been solved.
