| + | </ | ||
| + | Now you can start the bdii service: | ||

| + | Use the command below to see if the information is being published: | ||
| + | <code bash> | ||

| + | </ | ||
| + | It is therefore neede to install and configure NFS on **egi-cloud-ha**: | ||

| + | ==== Troubleshooting ==== | ||
| + | |||
| + | * Passwordless ssh access to egi-cloud from cld-nagios and from egi-cloud to cloud-0* has been already configured | ||
| + | * If cld-nagios does not ping egi-cloud, be sure that the rule "route add -net 192.168.60.0 netmask 255.255.255.0 gw 192.168.114.1" | ||
| + | * In case of Nagios alarms, try to restart all cloud services doing the following: | ||
| + | <code bash> | ||
| + | $ ssh root@egi-cloud | ||
| + | [root@egi-cloud ~]# ./ | ||
| + | [root@egi-cloud ~]# for i in $(seq 1 7); do ssh cloud-0$i ./ | ||
| + | </ | ||
| + | * Resubmit the Nagios probe and check if it works again | ||
| + | * In case the problem persist, check the consistency of the DB by executing (this also fix the issue when quota overview in the dashboard is not consistent with actual VMs active): | ||
| + | <code bash> | ||
| + | [root@egi-cloud ~]# python nova-quota-sync.py | ||
| + | </ | ||
| + | * In case of EGI Nagios alarm, check that the user running the Nagios probes is not belonging also to tenants other than " | ||
| + | |||
| + | * in case of reboot of egi-cloud server: | ||
| + | * check its network configuration (use IPMI if not reachable): all 4 interfaces must be up and the default gateway must be 90.147.77.254. | ||
| + | * check DNS in / | ||
| + | * check routing with $route -n, if needed do: $ip route replace default via 90.147.77.254. Also be sure to have a route for 90.147.77.0 network. | ||
| + | * check if storage mountpoints 192.168.61.100:/ | ||
| + | * check if port 8472 is open on the local firewall (it is used by linuxbridge vxlan networks) | ||
| + | |||
| + | * in case of reboot of cloud-0* server (use IPMI if not reachable): all 3 interfaces must be up and the default destination must have 192.168.114.1 as gateway | ||
| + | * check its network configuration | ||
| + | * check if all partitions in /etc/fstab are properly mounted (do: $ df -h) | ||
| + | |||
| + | * In case of network instabilities, | ||
| + | <code bash> | ||
| + | [root@egi-cloud ~]# / | ||
| + | generic-receive-offload: | ||
| + | </ | ||
| + | |||
| + | * Also check if / | ||
| + | <code bash> | ||
| + | [root@egi-cloud ~]# cat / | ||
| + | #!/bin/bash | ||
| + | case " | ||
| + | em1) | ||
| + | / | ||

| + | em4) | ||
| + | / | ||
| + | ;; | ||
| + | esac | ||
| + | exit 0 | ||
| + | </ | ||
| + | |||
| + | * If you need to change the project quotas, check " | ||
| + | <code bash> | ||
| + | [root@egi-cloud ~]# source admin-openrc.sh | ||
| + | [root@egi-cloud ~]# openstack quota set --cores 184 VO:enmr.eu | ||
