[Cluster-devel] Quorum framework for corosync + disk-based quorum?

2010-01-12 Thread Lars Marowsky-Bree
Hi Lon, Chrissie, and the rest of the team ;-) I'm going through my list of uh-oh, this is missing issues, and I noticed that I have a fairly strong need for disk-based quorum. I wonder what the current state/roadmap is, and how one could help? Regards, Lars -- Architect Storage/HA, OPS

[Cluster-devel] SCTP versus OpenAIS/corosync time-outs

2009-10-30 Thread Lars Marowsky-Bree
Hi all, David, I'm contemplating SCTP versus OpenAIS/corosync. Is dlm_controld(.pcmk) pro-actively informed if a single ring/link goes down, as to trigger faster SCTP recovery - or is it left for SCTP to time out on its own and proceed? If the latter - is there a way to auto-tune the SCTP

[Cluster-devel] libdlm: improve logging

The patch is fairly self-explanatory and quite trivial - syslog was a bit less than useful before. Index: libdlm/group/dlm_controld/dlm_daemon.h === --- libdlm.orig/group/dlm_controld/dlm_daemon.h +++

[Cluster-devel] [PATCH] libdlm: fix dlm_controld skipping lock spaces

2009-08-10 Thread Lars Marowsky-Bree
With several lock spaces, there was a chance that poll_fencing, poll_quorum, or poll_fs were reset after the earlier lock spaces had been iterated over by process_lockspace_changes(). This would cause the earlier lock spaces to not be recovered, since process_lockspace_changes() would not be

[Cluster-devel] [PATCH] fs/dlm: fix connection close handling.

2009-08-10 Thread Lars Marowsky-Bree
For some reason, connections which were closed were being put back on the work queue, causing a hang in trying to connect to a blocked node, or a crash trying to access a closed connection. David provided a fix which introduced the CF_CLOSE flag, but which still could trigger the crash. Chrissie
