similar to: Gluster / DRBD Anyone using either?

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Outdated?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"

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, 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, 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, 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:

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.

Hi We've got drbd going between 2 nodes:) ATM there is un-partitioned space on each node but (we think) they are syncing OK. It looks as though it has synced the whole partition (2GB) from the primary node 1 to the other node: node 1 smb1:/home/steve # cat /proc/drbd version: 8.4.4 (api:1/proto:86-101) GIT-hash: 3c1f46cb19993f98b22fdf7e18958c21ad75176d build by SuSE Build Service 1:

I reboot the master, replication resumes just fine, but the /data filesystem doesn't get automounted til I manually mount it. -- john r pierce, recycling bits in santa cruz

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

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 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".

Hi all, I've been wrestling with a problem with drdb and centos. I have successfully created one drbd resource, but when I try the create a 2nd, I get an error on one of the nodes: Lower device is already mounted. Command 'drbdsetup /dev/drbd1 disk /dev/hdd1 internal -1' terminated with exit code 20 The partition is not mounted from fstab etc and is newly created with parted after

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

Hi All. I have two running servers (drbd primary, drbd secondary). When there is a problem with one of them we switch to the second one. Currently on the /dev/drbd0 (it has /xxx ext3 filesystem directly on it) we have some filesystem problems (after fsck -n). I would like to correct these errors but the filesystem should be unmounted first (I would like to avoid it if possible). Is there a way

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
