Xen project Mailing List

Hi Walter,

You are welcome, here I send you the 4 files you asked for. Let's say I got Xen tools
compiling them from source, #make install xen-tools and so on... So the version is the
same for Xen 4.1.1 I'm using. It is Debian 6 (Squeeze).

And thanks for you offer, in fact I am really interested in getting DRDB working, never configured it.
I have found this: http://notes.benv.junerules.com/xen-drbd-and-live-migration/
which is a guide to have DRBD working with Xen and Live Migration without shared storage but I
haven't configured it yet. The thing is that I wonder if DRBD replicates img files.

I have all my DomUs in img, is it the same replication for LVM? And if it is, once there's a failure and
the backup takes over the VM, how can I resynchronize the image on it to the primary host using DRBD?

Thanks Walter,
Best regards,
Tony.

hi tony,

thanks for replying J, well:

- the file "/boot/.config-3.1.5"

- a domU config file with the disk remus section (don't know where you put them, maybe in "/etc/xen/.cfg")

- do you use drbd?

- the file "/etc/xen/xend-config.sxp"

- what version do you use? squeeze? xen? xentools?, drbd?

a lot of things, I know J, I got the xen 4.2 beta running on a squeeze box and use at the moment drbd for disk replication. in case you don't have drbd we could exchange knowledge.

thanks walter

Hi walter,

I can send you my kernel config file, /boot/.config-3.1.5. And, what other config files do you need?
Could you specify the full path please?

Tony.

hi tony,

i know it is another request, but could you send me the kernel file and the config files to get remus run with debian squeeze and kernel 3.1 or 3.2?

thanks a lot, walter

ps: what xen version do you use?

Hello everyone,

I have setup Remus on Debian Squeeze and kernel 3.1.5. Remus and disk replication works perfect for Ubuntu systems,
but when I start Remus for Windows Sever 2003 (running Microsoft Exchange Enterprise 2003) it crashes giving the
following error:

root@neutrino:~/working-remus# xm create exchange-hvm.cfg
root@neutrino:~/working-remus# remus exchange-hvm 192.168.2.4
qemu logdirty mode: enable
xc: error: Error when writing to state file (4a) (errno 104) (104 = Connection reset by peer): Internal error
qemu logdirty mode: disable
PROF: resumed at 1326315866.106150
resuming QEMU
tc filter del dev vif3.0 parent ffff: proto ip pref 10 u32
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
Exception xen.remus.util.PipeException: PipeException('tc failed: 2, No such file or directory',) in <bound method BufferedNIC.__del__ of <xen.remus.device.BufferedNIC object at 0x24b7510>> ignored
root@neutrino:~/working-remus#

It seems that on the backup remus or Xen cannot assign a vif1.0 to the DomU since #ifconfig -a doesn't show a new vif there
when starting remus.

Any help would be highly appreciated!

Tony.
