Re: ldmadmin mkqueue problem

Alan,
Yes. The data area is on our lustre-based storage, which for all practical purposes in ordinary data access behaves as Posix I/O. This does not seem to be the case for whatever ldmadmin is trying to do, however. If I move teh data area to a purely local disk, I do not get the F_WRLCK error from pqcreate, but still get a "mkqueue failed" error:

The file was apparently created, so why the "mkqueue failed" message?

-bash-3.00$ ls -l data

I don't know why this happened.

To test the product-queue, execute the command "pqcheck -vl-"
