So dlmglue calls dlmlock to downconvert the lock from EX => NL. However, in the next iteration, we see lock at PR. Strange. Anycase, I have created a patch that should provide more info. The patch is against the current mainline. It should apply against older trees. But may require a bit of tlc. Please re-run with the the following patch. http://oss.oracle.com/~smushran/0001-ocfs2-Patch-to-debug-hang-in-dlmglue-when-running-d.patch Coly Li wrote: > > Sunil Mushran Wrote: >> Can you send me the raw trace output. >> > Here is the compressed trace info. > > Thanks.
