I had a failure once where the kernel detected an inconsistency in the
file system and mounted it read only. I'm interested in testing this
but am not sure if/how I can remount read only a write mounted
filesystem.

Hi Everybody,
I'm looking for tests that demonstrate the characteristics of Red Hat
Cluster Behaviour.
So far, I came up with the following things myself:
normal operation:
1 Reboot node2
2 Reboot node1
3 Halt node2
4 Halt node1
5 Boot node2
6 Boot node1
hardware failures
7 On the node on which the cluster service is started:
• Pull out first ethernet cable of the traffic bond
• Wait for three minutes
• Pull out second Ethernet cable of the traffic bond
8 On the node on which the cluster service is started:
• Pull out first ethernet cable of the cluster interconnect bond
• Wait for three minutes
• Pull out second Ethernet cable of the cluster interconnect bond
9 On the node on which the cluster service is started:
• Pull out the SCSI cable
10 On the node on which the cluster service is started:
• Pull out the power cords
software failures
11 On the node on which the cluster service is started:
• Change the cluster service init script so 'status' always returns
'1' (failure)
I'm interested in what you use your self ...
Thanks in advance,
Ferry
