<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>
