Hi,
I have trying a probe network formed by 2 DomU nodes with a OCFS2 shared
disk.
The network data are:
Dom0:
Debian, kernel 2.6.26-1-xen-686
192.168.2.10/24
DomU (node 1):
Fedora10, kernel 2.6.27.21-170.2.56.fc10.i686.PAE
OCF01 - 192.168.2.100
DomU (node 2):
Fedora10, kernel 2.6.27.21-170.2.56.fc10.i686.PAE
OCF02 - 192.168.2.101
OCF01 & OCF02 can connect themselves for SSH without problem, but the
connection is registered as a Dom0 conection. Example:
If I connect from OCF02 to OCF01 for SSH, the connection with netstat is...
tcp 0 0 192.168.2.100:22
192.168.2.10:43532 ESTABLISHED 1493/0
It appear as a Dom0 conection, not as OCF02 conection. I think that this
is the problem.
The OCFS2 disk is mounted in the node1, but then, OCF02 is booted and it
can't mount the shared disk. The error received is:
...
(1339,0):o2net_connect_expired:1659 ERROR: no connection established
with node 0 after 30.0 seconds, giving up and returning errors.
(1879,0):dlm_request_join:1033 ERROR: status = -107
(1879,0):dlm_try_to_join_domain:1207 ERROR: status = -107
(1879,0):dlm_join_domain:1485 ERROR: status = -107
(1879,0):dlm_register_domain:1732 ERROR: status = -107
(1879,0):o2cb_cluster_connect:302 ERROR: status = -107
(1879,0):ocfs2_dlm_init:2756 ERROR: status = -107
(1879,0):ocfs2_mount_volume:1208 ERROR: status = -107
ocfs2: Unmounting device (202,17) on (node 0)
...
the errors are always relationed with a timeout problem with another
node. The reasons for a 107 error are: network problems, or access
problems for a firewall presence ... There are not firewall in a DomU any.
Perhaps, my xend network configuration is not the correct:
"xend-config.sxp":
-------------------------------
(network-script 'network-bridge netdev=eth1')
(vif-script vif-bridge)
(dom0-min-mem 128)
(dom0-cpus 0)
(vnc-listen '0.0.0.0')
(vncpasswd '')
(keymap 'es-es')
"xend-config-xenapi.sxp"
-----------------------------------------
(xen-api-server ((9363 none)))
(xend-relocation-server yes)
(xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$')
(network-script network-bridge)
(vif-script vif-bridge)
(dom0-min-mem 196)
(dom0-cpus 0)
(vncpasswd '')
Some idea?
Thank you very much,
Alberto
