...few CentOS 5.2 based Xen clusters at different sites. These are built around a group of 3 or more Xen nodes (blades) and some sort of shared storage (FC or iSCSI) carved up by LVM and allocated to the domUs. I am "managing" the shared storage (from the dom0 perspective) using cman+clvmd, so that changes to the LVs (rename/resize/create/delete/etc) are automatically and immediately visible to all the Xen hosts. However, this combination seems to be horribly unreliable. Any network hiccup more than a lost ping or two results in cman losing contact with the rest of the machines,...

Hi list. I am dealing with DRBD (+GFS as its DLM). GFS configuration needs a CLVMD configuration. So, after syncronized my (two) /dev/drbd0 block devices, I start the clvmd service and try to create a clustered logical volume. I get this: On "alice": [root at alice ~]# pvcreate /dev/drbd0 Physical volume "/dev/drbd0" successfully created [root at alice ~...

Hi, I''m using xen on two-node redhat cluster (CVS devel version), using lvm as storage backend. redhat cluster is used to synchronize LVM metadata (using clvmd) and as storage for domain configs and dom-U kernels (with gfs). Latest version of redhat cluster works with xen-2.0.4, but not with xen-2.0-testing. ccsd failed to start on 2.0-testing. Anyone knows what the problem is? I assume most feature on 2.0-testing will eventually moved to 2.0-stable?...

I'm trying to set up SAN-based shared storage in KVM, key word being "shared" across multiple KVM servers for a) live migration and b) clustering purposes. But it's surprisingly sparsely documented. For starters, what type of pool should I be using?

...tuff). When I watch the bootup on the console, I see an error: lvm.static: symbol lookup error: /usr/lib64/liblvm2clusterlock.so: undefined symbol: lvm_snprintf This error comes immediately after the "Activating VGs" line, so it appears to be triggered by the vgchange command in the clvmd startup file. I have another, identically configured, server which I have not updated yet. This server does not give this error. Everything seems to be working fine, so is this something I need to worry about? -- Bowie

...ng redhat or centos). If unsure about the multicast performance of your switches, use unicast (I needed this in some cases). - don't use a shared FS for your virtual machines. GFS2 works ok, but the IO performance of your virtual machines drops a lot. - because of the cluster, you can use clvmd. Even if not using clustered logical volumes, you can still decide to stop the volume on one server and start it on another via the pacemaker/heartbeat agents. - use pacemaker to manage virtual machines (and, if not using clvmd, to stop/start your lvm's using tags). For the xml files desc...

Hello, I''ve configured two xen hosts (dom0) sharing a LUN on a SAN. My firs obiective is to run different domU on the two hosts, and implement live migration between them. Subsequently, I''d like to implement HA, so if a xen host goes down, domUs will be restarted on the other one. What''s the better way to obtain this? I think I need a cluster file system to

Hi Everyboy ! I read that LVM2 is not cluster aware (specially with OCFS2) from different post on internet forum... If it's true, could someone could confirm this information and point me where i can find this affirmation in documentation ? I do some test with OCFS2 on LVM2 and it's seems to run correctly , so i have some interrogation about this fact ! If it's true that LVM2 are

Hi, when i start a Domain and the local block device is mounted i got an error message from xm, as expected. When i run a DomU from a SAN (FC Storrage) xm lets me happyly start the same DomU wiht the same filesystem on another Dom0. I have 2 Dom0 Server connected to the same FC Disks, managed by clvmd. Is there any way to prevent this scenario from happening because after booting the 2nd DomU with the same filesystem it is doomed..... regards Martin _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
