Re: [OSR-devel] OSR on DRBD+GFS

[Gordan B. <go...@bo...>]

Hi,

I'm trying to add support for DRBDs, and trying to stick with doing it 
in a way consistent with iSCSI support as far as it is possible. I'm 
seeing a few weird things, though.

In linuxrc.generic.sh:
[...]
# start iscsi if apropriate
isISCSIRootsource $rootsource
if [ $? -eq 0 ]; then
         loadISCSI
         startISCSI $rootsource $nodename
fi

# start drbd if appropriate
isDRBDRootSource $rootsource
if [ $? -eq 0 ]; then
         loadDRBD
         startDRBD $rootsource $nodename
fi
[...]

and in cluster.conf:
[...]
<clusternodes>
                 <clusternode name="sentinel1c" nodeid="1" votes="2">
                         <com_info>
                                 <rootsource name="drbd"/>

[...]

 From this, one would assume that isISCSIRootsource would return false 
and iSCSI not get initialized, and isDRBDRootSource would return true 
and get initialized.

This is the opposite of what I'm seeing. iSCSI gets started, and the 
modules loaded. DRBD doesn't.

Am I misunderstanding where $nodename is coming from? I'm not 
particularly bothered by iSCSI trying to start (and failing because the 
iscsi packages aren't in the rpm list), but that makes the drbd not 
starting all the more puzzling. :-/

Further on (unrelated to this), I get cman starting, but ccsd failing, 
so the boot-up aborts. But ps -aux | grep ccsd shows that ccsd is in 
fact already running. I haven't seen this behaviour before. The only 
thing I can think of that is different is that this is a 2-node cluster, 
which is much smaller than what I usually work with. (Yes I did set 
<cman two_node="1" expected_votes="2"/>)

Any ideas?
