<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Hi all,<br><br>I've a production system with this setup.<br><br>2 Xen servers in HA sharing DRBD resources.<br>
<br>DRBD resources are over LVM's.<br><br>DomU's are firewalls with differents VLAN's for each one. (There are not<br>I/O problems because I've not much read/write proccesses).<br><br>The DRBD setup is for each domU (we've 16 vm):<br>
<br>1 DomU<br>1 - DRBD for base system (5GB)<br>1 - DRBD resource for swap (512M)<br><br>We use a different port for each resource, and physical server are<br>connected through crossover 10gigabit wire. (not bandwidth problem)<br>
<br>For example:<br><br>resource VM1 {<br> on M1 {<br> device /dev/drbd38;<br> disk /dev/vg00/VM1;<br> meta-disk internal;<br> address <a href="http://10.0.0.1:7827/" target="_blank">10.0.0.1:7827</a>;<br>
}<br><br> on M2 {<br> device /dev/drbd38;<br> disk /dev/vg00/VM1;<br> meta-disk internal;<br> address <a href="http://10.0.0.2:7827/" target="_blank">10.0.0.2:7827</a>;<br> }<br>}<br><br>resource M1-swap {<br>
on M1 {<br> device /dev/drbd39;<br> disk /dev/vg00/VM1-swap;<br> meta-disk internal;<br> address <a href="http://10.0.0.1:7828/" target="_blank">10.0.0.1:7828</a>;<br> }<br><br> on M2 {<br>
device /dev/drbd39;<br> disk /dev/vg00/VM1-swap;<br> meta-disk internal;<br> address <a href="http://10.0.0.2:7828/" target="_blank">10.0.0.2:7828</a>;<br> }<br>}<br><br>THE PROBLEM.<br><br>If I do a "reboot" on the domU, the DRDB resource freezes and domU<br>
doesn't boot.<br>Then I've to kill the Xen proccess that are using drbd's resources of<br>this domU, set the drbd resource as secondary and start the domU again.<br>We'use the drbd helper script to manage drbd resources on xen.<br>
<br>Some idea?<br><br>Thanks in advance<br><br><br>_______________________________________________<br>drbd-user mailing list<br><a href="mailto:drbd-user@lists.linbit.com">drbd-user@lists.linbit.com</a><br><a href="http://lists.linbit.com/mailman/listinfo/drbd-user" target="_blank">http://lists.linbit.com/mailman/listinfo/drbd-user</a><br>
