Ok - in that case I hope someone else can tell you the right way to mount this (and it may well be fuseblk, but i've not used that myself) and I'll read the answer and learn :) In the past, for something like this I would have done mount -o loop,offset=32256 /dev/mapper/nintendo-backupos /mnt/backups but that probably isn't right for you, and isn't helpful (well, it become arduous to calculate the offset) if the type 83 partition wasn't the first one. -serge -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

I've done the copy from gnome-terminal just for testing, and the same thing happens, plain cp, no -p. I don't know :) I'm thinking about running a script that would change the files to the correct permission.. but this seems like a terrible way to go about fixing this. man acl says: Under "Object Creation and Default ACLs" 1. The new object inherits the default ACL of the containing directory as its access ACL. This works great :) I don't think man acl says anything about copying an object into a folder and what should happen to it, if it does I don't understand the words it's using. How do ACL's work when files get copied from somewhere to somewhere else (such as my jump drive to my ACL enabled partition)? Thank you for your consideration Paul.

so fuseblk is what is actually returning -EBUSY. What kind of
fs is actually on nintendo-backupos? Are there any interesting

Can you define 'extra work'? If you want it to be really fast, make sure that the VM backing stores are shared between the two servers, and at the same pathnames on both. With maverick you can ask libvirt to move the backing store for you. -serge -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam
problem while mounting an LVM

Re: problem while mounting an LVM
Well, it's possible that you have it mounted in another namespace. Can you provide output of: 1. ls -l /mnt/backup (make sure that directory exists :) 2. ls -l /dev/mapper 3. cat /proc/self/mountinfo 4. cat /proc/self/mounts 5. cat /proc/1/mountinfo 6. cat /proc/1/mounts thanks, -serge Quoting Tapas Mishra (mightydre...@gmail.com): > mount output is > /dev/sda1 on / type ext4 (rw,errors=remount-ro) > proc on /proc type proc (rw,noexec,nosuid,nodev) > none on /sys type sysfs (rw,noexec,nosuid,nodev) > none on /sys/fs/fuse/connections type fusectl (rw) > none on /sys/kernel/debug type debugfs (rw) > none on /sys/kernel/security type securityfs (rw) > none on /dev type devtmpfs (rw,mode=0755) > none on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) > none on /dev/shm type tmpfs (rw,nosuid,nodev) > none on /var/run type tmpfs (rw,nosuid,mode=0755) > none on /var/lock type tmpfs (rw,noexec,nosuid,nodev) > none on /lib/init/rw type tmpfs (rw,nosuid,mode=0755) > none on /var/lib/ureadahead/debugfs type debugfs (rw,relatime) > > nintendo is a volume group which holds these LVMs > > On Mon, Oct 4, 2010 at 2:20 PM, Jordon Bedwell wrote: > > > On Mon, 2010-10-04 at 14:13 +0530, Tapas Mishra wrote: > > > mount /dev/nintendo/backupos /mnt/backup/ > > > mount: /dev/mapper/nintendo-backupos already mounted or /mnt/backup/ > > > umount: /mnt/backup/: not mounted > > > > What is '/dev/nintendo'?

copying an rsync backup in a new LVM
I am not clear if I am doing the correct thing so some one point me to the correct thing. I created a snapshot Volume of an LVM which holded a guest OS. I mounted this snapshot and using I took a backup on a server connected remotely. Now on Server A I created a new LVM this server A is different from all the above servers. I created a filesystem on this LVM and want to copy the rsync backup in this filesystem on A. But after creating the new LVM which has just a filesystem but no OS installed how do I mount it so that the rsync backup which I am having some where I can copy and use this to have a new VM on A. -- ubuntu-server mailing list ubuntu-server@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-server More info: https://wiki.ubuntu.com/ServerTeam

Re: how to transfer an LVM Guest OS on KVM Lucid to another server
Tapas, There is a command virsh migrate --live instanceName qemu+ssh://vmserver06/system. Though I haven't had much luck with it. Check out the last post in this forum: http://ubuntuforums.org/showthread.php?t=1152271 The other option I have used is shutdown the virtual machine and just manually move over the xml and the file that runs the virtual machine. I would like to hear your take on any of this if you ever get it working correctly across 3 or more machines. The pain point is also having a shared NFS location for each server running KVM. I don't have any fancy SAN/NAS devices so I/O through gigabyte ethernet is a concern when running many virtual machine all trying to do disk I/O.

I am searching for some information. I used virt-manager to create 4 guest OS on KVM. Let us call this server A I am running another server where KVM is running call this server B.
