[Ocfs2-users] Locking Options for OCFS2

[Angelo McComis]

Hi all:
I am pending abandonment of OCFS2 on one of my projects due to how both the
application _AND_ OCFS2 are competing for locks on files.

Are there any methods by which I can extend the locking functionality of
OCFS2, disable it, make it behave more like NFS, or otherwise?

The hints I have of this as the culprit are some entries that mention
"invalid lock mode"

:Sep 25 12:11:30 host02 kernel: (4438,4):ocfs2_cancel_convert:3092 ERROR:
Dlm error "DLM_BADPARAM" while calling dlmunlock on resource
F00000000000000003b1341b545b16f: invalid lock mode specified

This is SLES10.2 and Novell has already provided the latest kernel which
contains the 1.4-4 patch. (2.6.16.60-0.39.3.PTF.524683.1-smp).

Novell is at their end of what they can do on this, so I am back to the
users list to see if there are different options I can tune with.

Thanks,
Angelo
