Host detection failes, if "hostname -f" returns no hostname

[speedbur]

The hostname on my machine seems to be invalid and the patcher could not get the hosts uuid, because the call to hostname -f failes.

"get_host_uuid_cmd = str(xecli) + str(" host-list hostname=`hostname -f` params=uuid --minimal")

[root@myhost patcher]# ./patcher.py
hostname: Unknown host
Error: Failed to obtain HOSTUUID from XE CLI

[root@myhost patcher]# hostname -f
hostname: Unknown host

Could not reboot the server machine right now, so i don't know if setting the hostname with "xe host-set-hostname-live uuid= host-name=example" will resolve that issue. I'll inform you later about this.

Ah yes, this is a valid issue since the last commit- I utilised hostname -f to identify the hostuuid of the current host (to differentiate against other nodes within a pool). This is naturally going to be an issue for anyone who has boxes without an FQDN. I'll have a rethink and see if it can be worked around.

Also seeing this same problem. Have reverted to the 1.1 release for now and it's working fine :) https://github.com/dalgibbard/citrix_xenserver_patcher/blob/70026d504c8b5bfd5b164aae067a27d901312bef/patcher.py

I've made an amendment here to switch it for checking against "address=" and using "hostname -i" (IP address) instead; this should fix it - could you possibly verify?

The commit is in 89036ae9ae2fb6a00c8a0bc7807cd8690c9e0c33

Unfortunately hostname -i also returns hostname: Unknown host :(

[speedbur]

Perhaps this could help you. if I call xe host-list using the name-label I get a valid result for my machine.

[root@mybox ~]# xe host-list name-label=`hostname` params=uuid --minimal
<guid of mybox>

[dalgibbard]

Yeah that's definitely valid. I do have conerns over what this returns when the node is a Master of a pool... but that's a seperate story. For the time being, i've added IP evaluation on the node, and am using that against "address" until I find a fix for #6 :-)

[speedbur]

Your evaluation from b92a06fa66d4adbae669425c029c1efb9d55a31a works on my machine :)

[dalgibbard]

I'll set this as closed me thinks :)
