[Xen-users] XCP - Lost NIC's...

[Kristoffer Egefelt <dr.fersken@xxxxxxxxx>]

Hi list,

we're testing XCP 1.0 build 42052 and have run into a strange issue.

One master, one slave in a pool, both configured with plain slb bond0
with management interface untagged, and vm networks/vlans on top of
the bond0
Setup has been running for a week with no problems.
This morning we cannot connect to the pool via xencenter.
SSH to master works, but theres no management interface configured and
no NIC's available - after reboot ssh do not work anymore.
Connecting to console, running ethtool eth0 says no link although
theres link on the switch.
Restarting network, running ifup/down, manually assigning ip's do not
work - theres no interfaces.

SSH to slave does not work.
Connecting to console, I cannot login to xsconsole when trying to do anything.

Running xe pool-emergency-transition-to-master on master - server
reboots and work :-)
Restarting slave, everything works, though the master cannot connect
to shared iscsi storage, SR_error 141.

Removing and reattaching the SR works.

The logfiles is not helping me much figuring out what happened -
master complains that it can't reach the slave, slave is not logging
anything.

Any hints is greatly appreciated.

Thanks! :-)
