similar to: FSCK on mounted filesystem (LVM/DRBD)?

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 am currently installing drbd on Centos 6.3 x86_64 and have two possible repos to choose. Which one in your opinion is better/provides more stable packages/etc.? Best regards, Rafal Radecki.

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:

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

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

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Outdated?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, i''ve a problem with drbd 0.7.10 module on an xenU OS (testing). I''ve compiling drbd with "make clean all" then "make install" without error. modprobe drbd OK with no error too and now and trying to start drdb /etc/init.d/drbd start Starting DRBD resources: can not open /dev/drbd0: No such device or address [ d0 can not open /dev/drbd0: No such device

Hi all. I am currently working for a hosting provider in a 100+ linux hosts' environment. We have www, mail HA solutions, as storage we mainly use NFS at the moment. We are also using DRBD, Heartbeat, Corosync. I am now gathering info to make a cluster with: - two virtualization nodes (active master and passive slave); - two storage nodes (for vm files) used by mentioned virtualization nodes

Hi all, Where i want to arrive: 1) having two storage server replicating partition with DRBD 2) exporting via GNBD from the primary server the drbd with GFS2 3) inporting the GNBD on some nodes and mount it with GFS2 Assuming no logical error are done in the last points logic this is the situation: Server 1: LogVol09, DRDB configured as /dev/drbd0 replicated to Server 2. DRBD seems to work

Hi All. I have a setup in which I have two servers serving nfs share. The nfs service is made highly available with pacemaker. When the primary server goes down the secondary starts nfs service. Service IP is floating between servers but they have NO "shared" storage/filesystem so NFS state/connection information in case of failover is lost. I have two clients. When the failover from

Hi guys I have few problems with live migration ... and I need some professional help :) I have 2 xen servers ... CentOS 5.3 and I want to have a high available cluster Now let`s begin .... xen0: [root@xen0 ~]# fdisk -l Disk /dev/sda: 218.2 GB, 218238025728 bytes 255 heads, 63 sectors/track, 26532 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start

Hi Everyone, I''m trying to get Xen to use a native DRBD device but it seems it will not create the virtual machine. It does not seem to like the DRBD device type, any ideas on what might be wrong? I''m pretty sure my xen config file is OK and the DRBD device looks fine too. Full details below. xm create centostest Using config file "./centostest".

I have a pair of centos 6 systems, with a rather large raid thats DRBD replicated from box 1 to box 2... box 1 mounts this as /data when box 1 reboots, /data doesn't get mounted, but the drbd replication starts up just fine. the entry in fstab is... /dev/drbd0 /data xfs inode64 1 0 once the system is booted up, if I `mount /data`, it mounts just fine.

Regardless of the filesystem (i''ve used reiserfs, xfs, ext3), whenever I mount a fresh DRBD partition I get some nasty kernel messages. This is under Debian Sarge, Xen kernel 2.6.11.12-xen0 (dom0) using DRBD v0.7.11 (pulled from Debian "testing"). This is what I did to create the partition. On both nodes I created a new LVM storage device and started DRBD: # lvcreate

Hi all. I am currently designing a server room. I would like to be able to draw a 2D (in the future 3D) project. Do you know any tools? Which one can you recommend? Best regards, Rafal Radecki.

Hi there First of all apologies for the lenghty message, but it's been a long weekend. I'm trying to setup a two node cluster with the following configuration: OS: Debian 6.0 amd64 ocfs: 1.4.4-3 ( debian package ) drbd: 8.3.7-2.1 lvm2: 2.02.66-5 kernel: 2.6.32-45 mdadm: 3.1.4-1+8efb9d1+squeeze1 layout: 0- 2 36GB scsi disks in a raid1 array , with mdadm. 1- 1 lvm2 VG above the raid1 ,

trying to follow the ha-drbd HOWTO on the centos wiki... I prep two identical systems with centos 5, leaving some disk space unassigned (they only have one scsi drive), create /dev/sda4 partitions on each to use for the repdata... I install the modules, create a /etc/drbd.conf like... [root at svfis-blade03 ~]# more /etc/drbd.conf # # please have a a look at the example configuration file in

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 ~]# vgcreate

Dear All, Currently using RHEL6 Linux and Kernel Version is 2.6.32-71.el6.i686 and DRBD Version is 8.3.10 DRBD is build from source and Configured DRBD with 2 Node testing with Simplex Setup Server 1 : 192.168.13.131 IP Address and hostname is primary Server 2 : 192.168.13.132 IP Address and hostname is secondary Finally found that drbd0, drbd1 mount failed problem *Found some error messages
