[Pacemaker] Possible bug?

[Borislav Borisov]

Hi all,

I am experiencing a very strange issue. On two test boxes I have a setup
that should server NFS and iSCSI Targets (SCST).

When I create couple of iSCSI Target groups, composed of Target/Lun, and I
decide to remove one an error occurs:

  Sep 10 15:24:40 Cluster-Server-1 cib: [48709]: WARN: Managed
write_cib_contents process 54564 killed by signal 6 [SIGABRT - Abort].
  Sep 10 15:24:40 Cluster-Server-1 cib: [48709]: ERROR: Managed
write_cib_contents process 54564 dumped core
  Sep 10 15:24:40 Cluster-Server-1 cib: [48709]: ERROR:
cib_diskwrite_complete: Disk write failed: status=134, signo=6, exitcode=0
  Sep 10 15:24:40 Cluster-Server-1 cib: [48709]: ERROR:
cib_diskwrite_complete: Disabling disk writes after write failure

I then executed 'killall -PIPE cib' on both boxes to force a reload. More
resources were added, this time NFS ones, composed FS/ExportFS.
When I delete any of those there is no problem, however, the second that I
remove an iSCSI one the Disk writes are disabled with the error above.

A core file gets generated when that problem occurs, but it did not help me
much:
Reading symbols from /usr/libexec/pacemaker/cib...done.

Something appears to be very wrong and I just can't figure out what. Any
help is appreciated.

Cheers.

P.S. I have attached the hb_report.
