<div class="moz-cite-prefix">Hi,<br>
<br>
Thanks for the input. We were using "-r" when we tested again this
morning, and paying closer attention to the log showed that the
problem is in the delete phase. The delete command seems to be
executed on the host that is unreachable (in this case bl05):<br>
<br>
Thu Mar 27 11:07:36 2014 [VMM][I]: fi" failed: ssh: connect to
host bl05 port 22: Connection refused<br>
Thu Mar 27 11:07:36 2014 [VMM][E]: Error deleting
/var/lib/one/datastores/109/416/disk.0<br>
Thu Mar 27 11:07:36 2014 [VMM][I]: ExitCode: 255<br>
Thu Mar 27 11:07:36 2014 [VMM][I]: Failed to execute transfer
manager driver operation: tm_delete.<br>
Thu Mar 27 11:07:36 2014 [VMM][I]: Command execution fail:
/var/lib/one/remotes/tm/shared/delete
bl05:/var/lib/one//datastores/109/416 416 109<br>
<br>
I attached a log for the VM running on host bl05.<br>
<br>
Thanks for the help,<br>
<br>

<div>The hook for host error in OpenNebula 4.4 allows to define
one, and only one, of the "-r" and "-d" flags:</div>
<div><br>
</div>
<div> * -r will "delete --recreate" the VM in the failed host,
this will go through the epilog_delete phase, and it should
erase the sym links and launch the VM again. This is probably
what you want, please come back if the problem does not go
away</div>
<div> </div>
<div> * -d will "delete" the VM in the failed host, but won't
launch the VM again.</div>
<div><br>
</div>
<div>These two are mutually exclusive. </div>

<div text="#000000" bgcolor="#FFFFFF"> <tt>Hello,</tt><tt><br>
</tt><tt><br>
</tt><tt>We've started using a system
datastore whith a shared storage in a
clustered fs, so we could start testing
the live migrate functionality. The live
migrate is working as expected, but when
testing the fault tolerance using the
host_hook, we noticed the following
error:</tt><tt><br>
</tt><tt><br>
</tt><tt>[TM][I]: ln -s
"/dev/vg-nebula/lv-one-144"
"/var/lib/one/datastores/109/393/disk.0""
failed: ln: failed to create symbolic
link
`/var/lib/one/datastores/109/393/disk.0':
File exists</tt><tt><br>
</tt><tt>[TM][E]: Error linking
/dev/vg-nebula/lv-one-144</tt><tt><br>
</tt><tt><br>
</tt><tt>I understand the error. When I
kill one node and host_hook kicks in,
being the storage shared between nodes,
the symlinks to the images are already
there.</tt><tt><br>
</tt><tt><br>
</tt><tt>My question is regarding the hook
definition:</tt><tt><br>
</tt><tt><br>
</tt><tt>HOST_HOOK = [</tt><tt><br>
</tt><tt> name = "error",</tt><tt><br>
</tt><tt> on = "ERROR",</tt><tt><br>
</tt><tt> command =
"ft/host_error.rb",</tt><tt><br>
</tt><tt> arguments = "$ID -r",</tt><tt><br>
</tt><tt> remote = "no" ]</tt><tt><br>
</tt><tt><br>
Is it possible to configure the hook to
delete the VM, and afterwards creating
it? We tried combining "-d" and "-r"
flags but only one flag seems to be
used.<br>
<br>
Thanks in advance.<br>
<br>
