Amahi Forums

We recently experienced a power failure that brought down our network (router and HDA) unexpectantly. Since the power failure the DHCP server is not working properly; it doesn’t assign IP addresses to the devices on the network. I’ve verified that the setting on the HDA network page are correct. Also, I’ve cycled the settings and the rebooted the HDA several times; the DHCP server still does not assign addresses. The router has been rebooted several times, as have all the devices on the network. The HDA DHCP appears to be ignoring all requests for an address. Is there a way to "reset" the DHCP server on the HDA? I've checked the various forums and have not found any obvious solutions.

Other relevant information: the router’s DHCP is presently assigning addresses; the HDA can see and ping the internet and the rest of the network. I appreciate any troubleshooting advice and counsel you can offer.

You might check out the dnsmasq troubleshooting guidance. The wiki can be quite helpful for common problems.

With a power outage, a hard shutdown can damage the file system. You may need to reinstall at some point if other issues develop.

What version of Amahi is this machine?

Thanks for the reply.

I'm run Fedora 25 with Amahi 10. Reinstall would be very difficult as I have a significant amount of data stored on shared drives in Greyhole. Is there a way to reinstall and not lose all my data in Greyhole?

One other thing I noticed: the NFS server and DNS service have stopped and won't restart.

Is there a way to reinstall and not lose all my data in Greyhole?

Yes. There is guidance in the wiki. See Moving Data Out of Greyhole and Reconnect Greyhole Storage Pool.

If you want to try and fix this versus reinstall, then will need to see some logs.

Seems as if there are multiple issues if others services are stopped and cannot be restarted.

I'd like to try and fix this. I have too much data stored on those drives to reinstall. What logs do you need?

Take a look at /var/log/boot.log.

Also are OS updates current: Keep in mind you may not have a choice but to reinstall. When a machine is hard shut down due to a power outage, it can damage the drive and/or file system. Once that occurs, there's no way to fix it.

I have the log; where / how should I upload it to you. Also, I'm unable to synchronize the update cache, so I believe that the OS is likely not up to date. Thoughts on how to resolve that?

After doing some research and poking around, it looks like the dhcpd service's files were corrupted. I've uninstalled and reinstalled, but the conf file is empty. Is there an automated way to recreate it? If not, can you send a sample I can use to build a proper one? Thank you for all your aid.
