ATA failover between datacenters
Hi Everyone, Does anyone know of any ATAs that can do proxy failover without using SRV. I don't want to rely on dns if at all possible. Basically, I have Asterisk boxes in two different data centers and I need ATAs to be able to uses the server at DC2 if DC1 goes down. The servers are already in a HA setup at each datacenter. I am looking for added protection if one of the datacenters

XCP
Hi there, We are using latest version of XCP on 6 hosts. While issuing VM.start or VM.start_on xmlrpc functional call , it says : {''Status'': ''Failure'', ''ErrorDescription'': [''SESSION_INVALID'', ''OpaqueRef:cfb6df14-387d-40a1-cc27-d5962cba7712'']} However if I put VM.start in a loop maybe after

Rsync between 2 datacenters not working
Hmmm, looks indeed like changing the mtu helps, strange thing is that with the bigger mtu sometimes I had no problems and often TB are copied without problems. Problem is I can't test the connection that much because the connection has been established by a third party and it is just some vlan without any hops. But thanks for the link to the nfs-test that looks interesting!

Rsync between 2 datacenters not working
If reducing the MTU is helping, you might look into turning on Path MTU Discovery. NFS can be fast for large transfers if you tune it. http://stromberg.dnsalias.org/~strombrg/nfs-test.html NFS is not terribly secure though - at least v2 and v3 weren't. Not sure about v4.

Rsync between 2 datacenters not working
You could try using an automounter, like autofs, in combination with sshfs. It'll be slower, possibly a lot slower, but it should be more reliable over an unreliable connection. I've been using: remote -fstype=fuse,allow_other,nodev,noatime,reconnect,ServerAliveInterval=15,ServerAliveCountMax=40,uid=0,gid=0,ro,nodev,noatime :sshfs\#root at remote.host.com\:/ BTW, I'm not sure

Xen with openvswitch integration
Dear all, Again, I have some question here and I hope some one have experience how to do it. I have Xen 4.2.1 installed from sources and working with XM toolstack. I will use this xen in order to run Remus high availability with DRBD. Does any one know about openvswitch integration with xm toolstack, since Xen wiki only confirm XCP have natively support openvswitch

XCP: disk2vhd -> xenconvert (to ovf) -> xe vm-import
Hi all, I`m evaluating methods for nightly "snapshot" a physical win2003 to xcp vm. I know it would be a lot easier and reliable just to to one convert one time and start to generate real vm snapshots, but at this time I cannot use this method. I tested the sequence: disk2vdh -> xenconvert (to xcp), but a big deal of using this method is that xenconvert does not send

XCP vs XenServer (free edition) or is it XCP mature enough?
Hello, I am a system manager of a datacenter. Is this moment, we about 30-40 xen servers running 2 or 3 domUs each of them. We are now using (standalone) xen over debian lenny. We manage each xen server independently, but we are looking for a central management console. At this moment, I have the doubt about using citrix xenserver (the free edition) or XCP. I didn''t know much

Redundant and Geobalancing setup
Hi, I use dovecot for a long time now, but only as a single isolated server each time. I joined a company a few years back. We had trouble with compagnies hosting our mail, supposedly full redundant and so on. The company is small, but we have many dealers around the world, and it's growing. Mail became the fist choice for clients to contact the dealers. No mail, and we loose sales. For

Remus blktap2 issue
Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:imagePath notation does not work for me, although this

BLKTAP
I noticed recently that there is no real easy way to get the kernel driver for blktap working in mainline. I''ve pulled down the source from Daniel Stodden''s linux git tree on xensource, but it looks like it''s for debian and I''m running Fedora 14, so I''m trying to sort it out. I run the 3.1.x kernel and don''t want to go back to the 2.6.32 that

How to get the checkpoint size in remus code?
Hi, I''m doing my master research and I need to adapt remus code. Now... I wanna get the checkpoint size (memory + disk) on each period. Does someone know what function does this? I think some *fd *object''s function in remus code could just get the memory size. Does someone help me? Thanks _______________________________________________ Xen-devel mailing list
