Hello all, I''ve just installed a new dom0 with openSUSE 11.3 (x86_64) and I''m seeing domUs crashes when reading from disks. The problem occours when in domU configuration I use memory=1024 maxmem=2048 My setup is DRBD on LVM on Software RAID 10 and drbd devices are used as disks for domUs, using phy:/dev/drbd0,hda,w phy:/dev/drbd1,hdb,w The domU in test is HVM, I''m

so I've had a drbd replica running for a while of a 16TB raid thats used as a backuppc repository. when I have rebooted the backuppc server, the replica doesn't seem to auto-restart til I do it manually, and the backupc /data file system on this 16TB LUN doesn't seem to automount, either. I've rebooted this thing a few times in the 18 months or so its been running... not

Hi, First of all, I'm new to ocfs2 and drbd. I set up two identical servers (Athlon64, 1GB RAM, GB-Ethernet) with Debian Etch, compiled my own kernel (2.6.16.20), then compiled the drbd-modules and ocfs (modules and tools) from source. The process of getting everything up and running was very easy. I have one big 140GB partition that is synced with drbd (in c-mode) and has an ocfs2

I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary (v8.3.8) and Pacemaker. Everything seems to be working great, except during testing of hard-boot scenarios. Whenever I hard-boot one of the nodes, the other node is successfully fenced and marked ?Outdated? * <resource minor="0" cs="WFConnection" ro1="Primary" ro2="Unknown"

Hi all, I am using OCFS2-1.4.7 for 2 servers which is running Red hat enterprise 5.7 kernel 2.6.18-274.el5. OCFS2 I use for drdb for replicating master-master. My 2 servers was installed HA-Proxy. Yesterday, server web1 was down with the log kernel panic. And today, web2 was down too. After that, I trace the log file on these server and found that the reason from ocfs2. The log

Hi all. I have two hosts with drbd: kmod-drbd83-8.3.8-1.el5.centos drbd83-8.3.8-1.el5.centos and kernel (CentOS 5.7): 2.6.18-308.4.1.el5 After a recent upgrade of kernel I have had two sitiuations when my ext3 filesystem on /dev/drbd0 became read-only. I've checked disks with smartctl -t long, they are ok. There are no messages with disks problems in /var/log/messages | dmesg. I've made

Hi all, I created a two node cluster that manages virtual machines with two servers connected via a cross cable on the network 10.0.0.0/24. I want that machines that runs on different servers in the network 172.16.0.0/24 can see all the others. To make this possible I've configured a vlan on each server: ... ... 5: eth1.111 at eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc

Hi all, I'm using libvirt with qemu-kvm and virtualbox on the same system. Everything is working, but I want to change the default uri fo virsh. At the moment, if i run: # virsh uri vbox:///system and because of this, if I try to list my vm(s) in this way: # virsh list --all Id Name State ---------------------------------- the output is empty. I need always to pass the

Hi, I set up a virtual environment based upon KVM/libvirt/pacemaker. When managing this I cannot use virt-manager or virsh, since everything is managed by the cluster. So when I need to migrate a vm I must drive the operation from pacemaker (via crm shell program). I'm ok with this kind of management, but what I need now is just a bare web interface to make the users see just the position (=

Hello List, i am running Debian Squeeze and i installed DRBD, 3.2.0-0.bpo.4-amd64 and Xen4.0 from the Backports.

Hi everybody, I'm using the PHP API to make a web interface interact with the virtual machines installed on some hypervisor. Everything is fine, but I would like to find a way to get the guest's cpu and mem usage, so that it should be possible to make some rrd graphs. I didn't find out anything and also it seems looking around that there is no way to obtain those data. What is strange

Hi, Sorry for the need of the long winded email. Looking for some answers to the following. I am setting up a xen PV domU on top of a LVM partitioned DRBD device. Everything was going just fine until I tried to test the filesystems in the domU. Here is my setup; Dom0 OS: CentOS release 5 (Final) Kernel: 2.6.18-8.1.4.el5.centos.plusxen Xen: xen-3.0.3-25.0.3.el5 DRBD:

Hello, for some strange reason I can not get quota to work with Samba 3.5.8. The quoata system itself works fine (using "repquota /mountpoint") and via NFS, but Samba does not report the correct free space (df command in smbclient). Instead the real free space on the disk volume is shown to smb clients (tested from Windows and smbclient). The quotasystem in use is the new quota

Hello list, If i take a drbd over two hosts configured as dual primary, i can access files via ocfs2 from both sides. For this, on both sides i'ld have to mount the ocfs2-partition locally and both sides have their own ocfs-DLM, as far as i understood? So in Detail: 1. /dev/drbd0 configured in dual primary, taking one partition from each host 2. drbd0 is ocfs2 formatted 3. ocfs2-tools are

a previously rock solid reliable server of mine crashed last night, the server was still running but eth0, a Intel 82574L using the e1000e driver, went down. The server has a Supermicro X8DTE-F (dual Xeon X5650, yada yada). server is a drbd master, so that was the first thing to notice network issues. Just a couple days ago I ran yum update to the latest, I do this about once a month.

Hiya, I'm new to Centos but learning rapidly but I have been using FreeBSD. I'm trying to setup a HA NFS server using 2 machines. Both machines are running 4.3 updated to the latest via Yum. I did yum groupinstall drbd-heartbeat and yum install kernel-module-drbd-kernel-module-drbd-2.6.9-34.EL to match my kernel. The problem I have is that on 1 machine drbd works fine, but when I start

We're trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) . Setting up a single primary disk and running bonnie++ on it works. Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ works When setting up ocfs2 on the /dev/drbd0
