similar to: DRBD on a xen host: crash on high I/O

Hi. The short story... Rush job, never done clustered file systems before, vlan didn't support multicast. Thus I ended up with drbd working ok between the two servers but cman / gfs2 not working, resulting in what was meant to be a drbd primary/primary cluster being a primary/secondary cluster until the vlan could be fixed with gfs only mounted on the one server. I got the single server

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.

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 guys! I can?t find an answer in google, so my last hope is this mailing list. Story. I have two servers with same arrays. Servers connected by DRBD. I used ocfs2 as file system, also I used NFS4 to access to the ocfs2 drive. I do not have any idea, but the allocated descriptors in /proc/sys/fs/file-nr increasing every time while drive accessed. So after some time allocated descriptions over

Hi, I would normally post this to the drbd list but it so low traffic/low volume (plus Austria might be asleep right now) I figured i'd ask someone here in case they have gotten drbd working on centos. Right now my system says i'm only the 971st person to even install it... It's been out for years, so likely this just means version 8. But you'll only see a couple of posts

centOs5.5/samba4/named here is a short guide setting it up to work. I added TSIG for bind-master amd bind-slave. Update to samba4 alpha13 added (installing git on CentOs 5.5).

First of all do not install the bind

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.

Hi to all, I am mounting a simple cluster for use mail/virtualbox/samba in two servers, in active/active mode (not for virtualbox). In my testings some times the drbd system needs wait some time for start (sync protocols), or because some times the node are down many days. I create a script for wait for a sync, and check that the "ip of interconect cluster" are up an running. and go up

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".
