</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 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>
Regards,<br>
