Re: [Linux-cluster] DLM & RedHat Enterprise Linux



Patrick,

Is the query functionality implemented yet?
I defined QUERY in dlmtest.c and I am getting this:
# dlmtest -Q
locking LOCK-NAME EX ...done (lkid = 102da)
Query failed: Invalid argument
unlocking LOCK-NAME...done

Regards,
Christos

It looks like the default lockspace didn't get released when the all
references to it disappeared (unless you have something holding it open!).

I'm not sure how that might happen
