[Xen-devel] Remus stopped with full protection

Remus stopped with full protection.
Hi everyone:

I am trying to deploy Remus on two servers following the instruction on the
official

website http://dsg.cs.ubc.ca/remus/doc.html. I''ve succeeded runnig
Remus
using "remus -

-no-net myvm mybackuphost". I can see a continual stream of messages on the
primary host

and I can do failover even pulling the power plug using the shared storage
DRBD.

The problem occurs when I want to step further and try to add disk
replication and

network buffering as the official documentation said.

I let each of the physical hosts has an identical copy of the disk image
available at the same path like /dev/vgxen/hvmsnap .

Then,I create the hvm and do the remus without "--no-net":
[root@server2 img]# xm list
Name                                        ID   Mem VCPUs      State

Rhel5-hvm1                                   1   512     1     r-----

[root@server1 img]# remus 1 server2
qemu logdirty mode: enable
Saving memory pages: iter 1   0%ERROR Internal error: Error when writing to
state file
(4a) (errno 104)
Save exit rc=1
qemu logdirty mode: disable
then the program stops.

The error is located at line1361 xc_domain_save.c. The errno 104 standard
for "connection reset by peers".
I''m not sure whether there there are some mistake about the network
socket.

I''ve been stunked by this for two weeks. Do I miss something or could
anybody tell what I should do next.

Thanks for any feedback and suggestion!


Following are some additional infomation:

I have updated xen-unstable to the lastest tip, so it includes patches
against Remus

like ''IMQ for linux'',''control tool'', as well
as ''Patch * of 2'' deliveryed on
02 Dec.


Some details about my enviroment:
Two homogeneous servers each with 4 GB of memory and 160 GB of hard disk.
Rhel5.3 x86_32 with kernel 2.6.18.8 compile against xen-unstable.

I have this xen HVM:
  1 import os, re
  2 arch = os.uname()[4]
  3 if re.search(''64'', arch):
  4     arch_libdir = ''lib64''
  5 else:
  6     arch_libdir = ''lib''
  7 kernel = ''/usr/lib/xen/boot/hvmloader''
  8 builder = ''hvm''
  9 memory = ''512''
 10 disk = [
''tap:remus:server1:9000|aio:/dev/vgxen/hvmsnap,hda,w'']
 11 #disk = [
''tap:aio:/home/ninja/img/hvm.img,hda,w'',''file:/home/ninja/img/CentOS-5.3-

 12 #disk = [

  c:cdrom,r'']
 14 #disk = [
''tap:aio:/home/ninja/img/hvm.img,hda,w'',''file:/var/ftp/pub/rhel-server-5.

  3-i386-dvd.iso,hdc:cdrom,r'']
 15 vif = [''type=ioemu, mac=00:1c:3e:17:22:13'']
 16 #boot = ''dc''
 17 boot = ''c''
 18 name = ''Rhel5-hvm1''
 19 acpi = 1
 20 apic = 1
 21 device_model = ''/usr/'' + arch_libdir +
''/xen/bin/qemu-dm''
 22 vnc=1
 23 vncdisplay=2
 24 sdl=0
 25 opengl=1
 26 vnclisten="0.0.0.0"
 27 vncpasswd=''''
 28 serial=''pty''

disk = [
''tap:remus:server1:9000|aio:/dev/vgxen/hvmsnap,hda,w'']
hvmsnap is a lvm snapshots using as the hvm disk path.

location of the error code:
1351                 if ( pagetype != 0 )

1355                     if ( run )
1356                     {

1358

1363                             goto out;
1364                         }
1365                         run = 0;
1366                     }
1367                 }

 some other operation records:
I also have tried using paravirtualized virtual machine as GuestOS, yet it
is still failed with the same error.

Are here any errors in /var/log/xen/xend.log on either host?

Re: [Xen-devel] Remus stopped with full protection

Thank you very much for your reply.

I create hvm using spicified remus configuration file(add
''tap:remus''):

[root@server1 img]# xm list
Name                                        ID   Mem VCPUs      State
Time(s)
Domain-0                                     0  2046     8     r-----
1505.3
Rhel5-hvm1                                   2   512     1     ------
28.2

The state of HVM first appears as ''r'',then after a while it
turns into ''no
status'' like above.Since Remus claims that it will will block writes to
disk
until I start the remus script, so I guess this is the normal condition.(I
tested the image with common operation like ''xm create''
without using
"tap:remus"  and logging in with vnc. it is ok)

Following is the contents of xend.log since I create a HVM and run remus
script. it seems that there is no infor about running ''#remus myvm
backuphost'' but only infor on creating hvm.

I notice that there is an error "AttributeError:
''NoneType'' object has no
attribute ''memory_sharing''" at line 2483. I
don''t know whether it is the
reason that causes remus failed. Maybe I should fix this problem first.

Brendan has posted "HVM live migration error, probably related to
20691:054042ba73b6 " on 21, Jan. The problem is much like that I
encountered, yet the version of my xen-unstable is 20550.
