Rebuilding Cloud Stack Management (Recovery Fails)

[Amin Samir]

Hello,


I would much appreciate if someone helps, our cloud stack server crashed due to hard disk failure, thankfully we had a mysql database dump and backup of /etc/cloudstack/ folder, we are following the following steps to recover it:

1) Replaced the failed hardisk, reinstalled Ubuntu 12.04 LTS, and ran apt-get dist-upgrade

2) Installed CS 4.2.1, usage, and mysql, modified my.cnf

3) cloudstack-setup-databases cloud:***@localhost --deploy-as=root:ourpassword -e file -m ourpassword -k ourpassword

4) mysql -u root -pourpassword cloud < cloud-backup-date.sql

5) mysql -u root -pourpassword cloud_usage < cloud-usage-backup-date.sql

6) Removing the Host > General Tab > Tags by editing the tags and un-checking each one in each host in the cluster.

7) Service cloudstack-management start, service cloudstack-usage start.

8) Reboot the system VM's

The environment are as follows:

? 1 management server Ubuntu 12.04 LTS

? Cloud Stack 4.2.1

? Xen Server 6.1 Fully patched as of today.


Yet the tailing the log files give the following:


Unable to reach Pool[1|NetworkFilesystem]

com.cloud.exception.StorageUnavailableException: Resource [StoragePool:1] is unreachable:

Unable to send command to the pool

Unable to obtain VM statistics.

Unable to obtain host 4 statistics.


Can anyone please help how to recover this management server?


Thanks in advance.


Kind Regards

Hello,

We figured out what was the issue, we thought of sharing it with you, we had to comment the /etc/hosts entry 127.0.1.1 and submit the right name and ip info, then commenced communicating with the hosts and DB.

Amin,

though it seems strange to ever remove the localhost entry from
/etc/hosts, thank you for sharing. It is worth noting and I will keep
this in mind for future reference.

Regards,
Daan
