[D] Issue with Fenced [cloudstack]
GitHub user leo79901 created a discussion: Issue with Fenced
HI,
I have configured the host's HA provider and enabled Out-of-band Management (OOBM). I have also tested the OOBM functionality and am sure that it is working properly.
Then the HA state of the host was initially set to Available.
However, when I cut the power of one host, the host enters the `Fencing` status within 1 minute and remains in that state for more than 1-3 hour. After that, the status changes to fenced, and the VMs on the host are restarted on other hosts by the HA.
At the same time, I saw this on the ShapeBlue's website:
```
Fencing – the Host-HA framework is trying to Fence the host by issuing OOBM job
```
Yes, I have seen these logs. ACS try to shutdown the host by OOBM but faild. thers is 2100 try's with a host down.
```

## So my issue are:
**Why does the fencing process take such a long time?**
**How can I make the HA process quicker?**

Sorry , the checking code should be here：
```
public boolean fence(Host r) throws HAFenceException {
try {
if (outOfBandManagementService.isOutOfBandManagementEnabled(r)) {

if (r.getStatus().equals(Host.Status.DOWN)) {

I don't know much about Java. This is just a conclusion drawn from my little understanding of the code.
I think there may be a bug.
I found these code here:
```
@Override
public boolean fence(Host r) throws HAFenceException {
try {
if (outOfBandManagementService.isOutOfBandManagementEnabled(r)){
final OutOfBandManagementResponse resp = outOfBandManagementService.executePowerOperation(r, PowerOperation.OFF, null);
return resp.getSuccess();
} else {
LOG.warn("OOBM fence operation failed for this host " + r.getName());
return false;
}
} catch (Exception e){
LOG.warn("OOBM service is not configured or enabled for this host " + r.getName() + " error is " + e.getMessage());
throw new HAFenceException("OBM service is not configured or enabled for this host " + r.getName() , e);
}
}
```
ACS wants to shut down the host by IPMI in the `fencing` step.
from here:
```
if (outOfBandManagementService.isOutOfBandManagementEnabled(r)){
final OutOfBandManagementResponse resp = outOfBandManagementService.executePowerOperation(r, PowerOperation.OFF, null);
```
finally , it run this command:
`
/usr/bin/ipmitool -I lanplus -R 1 -v -H 10.21.0.22 -p 623 -U root -P XXXXXXXXX chassis power off
`
But it is wrong while shutting down a server which is already shut. I have run it manually and get this error.
```
[root@idnode1 ~]# /usr/bin/ipmitool -I lanplus -R 1 -v -H 10.21.0.22 -p 623 -U root -P XXXXXXXXX chassis power off
Set Chassis Power Control to Down/Off failed: Command not supported in present state
```
So it was run again and again.
Maybe we can add some code to resolve it.
Return true if the host is already down
```
public boolean fence(Host r) throws HAFenceException {
try {
// check host status
if (r.getStatus().equals(Host.Status.DOWN)) {
LOG.info("Host " + r.getName() + " is already down. Returning success.");
return true;
}
if (outOfBandManagementService.isOutOfBandManagementEnabled(r)) {
final OutOfBandManagementResponse resp = outOfBandManagementService.executePowerOperation(r, PowerOperation.OFF, null);
return resp.getSuccess();
} else {
LOG.warn("OOBM fence operation failed for this host " + r.getName());
return false;
}
} catch (Exception e) {
LOG.warn("OOBM service is not configured or enabled for this host " + r.getName() + " error is " + e.getMessage());
throw new HAFenceException("OBM service is not configured or enabled for this host " + r.getName(), e);
}
}

@leo79901, have you tested this? I think that the host status is changed to `Down` after the host is fenced not before that

Yes, sometimes the host was shut down due to power, CPU, or board issues, so this problem occurred.

thanks @leo79901 , could you enter a PR with this change? We can discuss and test it there. At first sight there is nothing wrong with your proposed code.

One suggestion here if you're using a build with this change
```
