<font size=2 face="Verdana">Hi,</font>
<br><font size=2 face="Verdana">a similar or related use case that we tried
to solve without success:</font>
<br><font size=2 face="Verdana">- a stretch cluster with two disk boxes</font>
<br><font size=2 face="Verdana">- a LUN on each disk box guarded by an
individual SFEX</font>
<br><font size=2 face="Verdana">- a mirror (raid1 or clvm) that survives
an outage of one disk box</font>
<br><font size=2 face="Verdana">- the mirror should be started if at least
one SFEX can be obtained and the other one could not be obtained on a different
node</font>
<br>
<br><font size=2 face="Verdana">IMHO sdb is not an alternative as this
introduces a SPOF.</font>

Dependency on either of two resources</font>
<br>
<hr noshade>
<br>
<br>
<br><tt><font size=2>Hi all,<br>
<br>
just wondering, is there a way to make resource depend on (be colocated<br>
with) either of two other resources?<br>
<br>
Use case is iSCSI initiator connection to iSCSI target with two portals.<br>
Idea is to have f.e. device manager multipath resource depend on both<br>
iSCSI connection resources, but in a "soft" way, so fail of any
single<br>
iSCSI connection will not cause multipath resource to stop, but fail of<br>
both connections will cause it.<br>
<br>
I should be missing something but I cannot find answer is it possible<br>
with current pacemaker. Can someone bring some light?<br>
<br>
Best,<br>
Vladislav<br>
