[Xen-users] Centos 5.2 using LVM -> DRBD 0.82 -> Xen Problems

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".

Error: Device 768 (vbd) could not be connected. /etc/xen/scripts/block
failed; error detected.

 

 

drbd.conf contents:

global { usage-count no; }

resource xendrbd0 {

  protocol C;

  startup { wfc-timeout 0; degr-wfc-timeout     120; }

  disk { on-io-error detach; } # or panic, ...

  net {  cram-hmac-alg "sha1"; shared-secret
"whateverpass";allow-two-primaries;after-sb-0pri
discard-zero-changes;after-sb-1pri discard-secondary;max-buffers 8192; }

  syncer { rate 500M; }

  on mrhappy.whatever.com {

    device /dev/drbd0;

    disk /dev/data1/dns1;

    address 192.168.10.160:7788;

    meta-disk internal;

  }

  on mrtickle.whatever.com{

    device /dev/drbd0;

    disk /dev/data1/dns1;

    address 192.168.10.161:7788;

    meta-disk internal;

  }

}

I guess the drbd type of block device is unknown to xen. /dev/drbd0 is 
just a standard block device, so it should be something like :

disk = [ ''phy:/dev/drbd0,hda,w''
,''file:/root/centos52.iso,hdc:cdrom,r'' ]

In any case, I would advise you to slice your drbd device with lvm so 
you have more flexibility in block device management.

Cheers,

Denis

Re: [Xen-users] Centos 5.2 using LVM -> DRBD 0.82 -> Xen Problems

You might want to read the messages I''ve posted here recently with the 
subject "drbd 8 primary/primary and xen migration on RHEL 5".

The block-drbd script provided by drbd (which enables the "drbd:"
syntax
in xen config files) does not work, at least not on HVM vms (I haven''t 
tested PVMs). By the time the script is executed, qemu-dm is already 
running and has already bailed on the device.

You can try using my qemu-dm wrapper script found at this URL:

http://www.antibozo.net/xen/qemu-dm.drbd

Save the wrapper script as /usr/lib64/xen/bin/qemu-dm.drbd, and modify 
the "device_model" line in your xen config file to point to the
wrapper
script.

Alter the disk line to use "phy:/dev/drbd0" instead of using the 
"drbd:drbd0" syntax. Make sure drbd0 is in secondary state *on both 
peers* before you start the vm. The script logs to the daemon facility, 
so watch your /var/log/messages.

Let me know how it goes.
