[Xen-users] tap2:remus:backup_ip:9000|aio:/path_to_disk.img not working - OSError: [Errno 2] No such file or directory
Hello,
I''m using Xen (installed from source - "hg clone
http://xenbits.xen.org/xen-4.0-testing.hg") on Debian Lenny. Dom0 kernel is
2.6.32-bpo.5-xen-686.
Until now I have successfully ran the Lucid Ubuntu as domU guest, defining
disks as (and also as file:):
disk = [''tap2:aio:/home/xen/domains/lucid/disk.img,xvda1,w'',
''tap2:aio:/home/xen/domains/lucid/swap.img,xvda2,w'']
However, when I try "disk
[''tap2:remus:backup_ip:9000|aio:/home/xen/domains/lucid/disk.img,xvda1,w'',
''tap2:remus:backup_ip:9000|aio:/home/xen/domains/lucid/swap.img,xvda2,w'']"
I
have no luck.
Please, can you tell me what''s wrong? I have spend so many time
googling,
but no one seems to address this issue.
Can someone tell me if this happens when installing xen hypervisor directly
from deb packages (version 4.0 for Debian squeeze)?
I''ll appreciate your help (I''m really stuck).
Thanks in advance.
Best regards,
Manuel Silva

Can you confirm that you have the remus part working correctly? Hope that helps.

Re: [Xen-users] tap2:remus:backup_ip:9000|aio:/path_to_disk.img not working - OSError: [Errno 2] No such file or directory
Hello Todd,
thank you sou much for your support.
In fact, I can run "remus --no-net myvm backvm".
However, when I try (without --no-net option) "remus -i 1000 myvm
backvm",
it returns:
Disk is not replicated: tap:aio:/home/xen/domains/lucid/disk.img,xvda1,w
Disk is not replicated: tap:aio:/home/xen/domains/lucid/swap.img,xvda2,w
modprobe -q sch_queue
Traceback (most recent call last):

xen.remus.device.BufferedNICException: could not load sch_queue module
I tried to install sch_queue from
"/home/altino/xen-4.0-testing.hg/tools/remus/kmod", but without
success.
I''m using Debian Lenny 5 and kernel 2.6.32-bpo.5-xen-686 (from apt-get
install linux-image-2.6.32-bpo.5-xen-686).
Should I try linux-image-1.6.18 from xen (hg clone
http://xenbits.xensource.com/linux-2.6.18-xen.hg)?
Everything seems to work with Xen, except Remus. I simply cannot synchronize
VM''s (principal and backup), since I cannot define
"tap2:remus:backup_ip:port|aio:path_to_file" (but I can use
tap2:aio:path_to_file).
Kind regards,
Manuel

Re: [Xen-users] tap2:remus:backup_ip:9000|aio:/path_to_disk.img not working - OSError: [Errno 2] No such file or directory
Dear Todd, I have Xen and this features working: - xm migrate --live myvm mybckphost - remus -i 200 myvm mybckphost However, I just simply cannot put remus working in order to synchronize disks. It''s impossible to specify "tap2:remus:backup_ip:port|aio:path_to_file". It keeps giving me the error "*mounted = devtype in [''tap'', ''tap2''] and taptype != ''aio'' and taptype != ''sync'' and not os.stat(fn).st_rdev OSError: [Errno 2] No such file or directory: ''backup_ip:9000|aio:/home/xen/domains/lucid/disk.img*" What do you mean with "*backup_ip:9000|aio:/home/xen/domains/lucid/disk.img is not addressable*"? Image file */home/xen/domains/lucid/disk.img* does exists and works when specifying "tap2:aio:/home/xen/domains/lucid/disk.img" (in this case without Remus). Note: I''m using Paravirtualized, not HVM. Really, after googling weeks, I don''t know what else do...

[Xen-users] Re: tap2:remus:backup_ip:9000|aio:/path_to_disk.img not working - OSError: [Errno 2] No such file or directory
hello Manuel, I met the same problem with you. ''tap2:aio:/home/xen/domains/lucid/disk.img,xvda1,w'' is OK. But when using ''tap2:remus:backup_ip:9000|aio:/home/xen/domains/lucid/disk.img,xvda1,w'' ,have no luck!!And the error message is as same as yours. my system info is as follows: xen version:xen-4.2-unstable dom0 kernel:2.6.40 dom0 OS type: centos-5.5(x86_64) domU type:PV I have googled weeks,but have no constructive results. Have you addressed this problem and how? best regards~ -- View this message in context: http://xen.1045712.n5.nabble.com/tap2-remus-backup-ip-9000-aio-path-to-disk-img-not-working-OSError-Errno-2-No-such-file-or-directory-tp3312775p4736626.html Sent from the Xen - User mailing list archive at Nabble.com. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
