{ocfs2}->{dlm}->{fencing}->{timeout}

> Hi!
>
> I observed an interesting thing: In a three node cluster (SLES11 SP4) with
> cLVM and OCFS2 on top, one node was fenced as the OCFS2 filesystem was
> somehow busy on unmount. We have (for paranoid reasons mainly) an excessive
> long fencing timout for SBD: 180 seconds
>
> While one node was actually reset immediately (the cluster was still waiting
> for the fencing to "complete" through timeout), the other nodes seemed to
> freeze the filesystem. Thus I observed a read delay > 140 seconds on one
> node, the other was also close to 140 seconds.
>
> This was not expected for a cluster filesystem (by me).

> I wonder: Is that expected bahavior?
