runs every 5 minutes to rsync /var/spool/torque/server_priv , and failover is

mix.<BR><BR><BR><PRE class=moz-signature cols="72">Daniel Bourque

<DIV><SPAN>This may indeed work now with the HA version of TORQUE. I
haven't had the time or opportunity to work on it lately but have the same
idea as you Daniel. The problem with TORQUE in tha past is as described
by Prakash. But now that TORQUE, using the --HA option of 2.3.0+
versions, allows you to have multiple entries in the "server_name" file,
TORQUE may no longer suffer from the same issues. </SPAN></DIV>

Re: [torqueusers] ha-torque using DRBD<BR><BR></DIV>
<DIV>Hi,</DIV>
<DIV><BR></DIV>I tried this some months ago for Torque, but failed. Looks
like, as mentioned by Stewart Samuels in an earlier thread, TORQUE uses
the gethostbyname routine to identify the host and therefore, when
failingover, you eventually must have the failover node be identified as the
original system. Which is not the ideal thing to do in a heartbeat
environment.
