Check whether the following points were taken into account for the selection of BS2000 files which are to be made available in a bs2fs file system:
The wildcard in the resource option should be selected in such a manner that if possible only the BS2000 files which are actually needed are mounted as the number of mounted files influences the performance.
If it is syntactically not possible or only extremely difficult to separate the required files from those which are not required, one of the following options for bypassing this problem should be considered before mounting files for the first time: export the files required to another pubset (under the same or a different user ID) or rename these BS2000 files with meaningful names.
You should avoid the same BS2000 files being mounted several times at different positions. This occurs when multiple mount operations are executed with identical or overlapping resource specifications. If such a file is open for write accesses in one of the bs2fs file systems involved, it cannot be opened simultaneously in another bs2fs file system.
If required, start additional copy daemons with the start_bs2fsd command.
