Hi everyone, This patchset is the latest approach I''m using for the Ceph storage daemon to keep track of which data has safely committed to disk. The basic idea is to not use the (problematic) user transaction ioctls at all. Instead, the daemon quiesces its own write requests, initiates an async snapshot, and then continues. The snapshot approach is nice because it provides rollback.

There are several bugs at error path of create_snapshot() when the transaction commitment failed. - access the freed transaction handler. At the end of the transaction commitment, the transaction handler was freed, so we should not access it after the transaction commitment. - we were not aware of the error which happened during the snapshot creation if we submitted a async transaction

This simulates a dirty shutdown to permit a later automatic power on. OS X uses this mode

Hi I'm quite new to KVM/libvirt0 so hope you can help I'm using Ubuntu Lucid 10.04 and libvirt0 0.8.1 When I try a :- snapshot create vm_name I get an error, ie 'error -5 while writing' Googling doesnt bring anything up. Taking snapshots of a vm when it isnt running works fine. Can I really only create snapshots of a vm when it isnt running ? -- Kind regards Julian

Hi Chris, This is the extent of my current queue of Btrfs snapshot/subvol/commit stuff. Most of these were posted several months ago. Can be sent upstream during this merge window? Not having this functionality is becoming a bit of a roadblock for our efforts to keep the Ceph data in a consistent state. These patches are also available from

Hi, how to save the current state of the running vm as a file and restore the last running state later by using the file as a arg of qemu cmd line? bruce _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I am trying to use virsh's snapshot-create command on a VMWare vm that has multiple disks in its device list, but the command is failing with the error: "Could not create snapshot: FileNotFound - file [pool] filename.vmx". However, this command works if my vm only has one disk in its device list. I am using libvirt 0.9.10, and the storage pool is nfs mounted between the machine that

Hi everybody, I am trying to take snapshot of a particular iscsi disk mounted inside the guest operating system. I have created my own snapshot feature for that. Could someone please suggest the better choice for stopping read/write operations on disk out of the two to take snapshots, or if you have any better solution, 1) freeze filesystems ( using domfsfreeze ) and then take the snapshot or,

Hi there, I''m running several VMs within Xen, and now I''m trying to create/revert snapshots of my VMs. Along with Xen and blktap2, another utility, vhd-util is also delivered, and according to its description, i guess I can use it to create/revert VM snapshots. To create a snapshot is actually easy, I just call |vhd-util snapshot -n aSnapShot.vhd -p theVMtoBackup.vhd | But

Hi, I want to take snapshots of a iSCSI devices from a target that hasn't snapshot/cloning capabilities (it's a Infortrend A16E storage array). What method are you using to make snapshots/clones of iSCSI targets using Open-iSCSI + CentOS? What about using Open-iSCSI + LVM snapshots system? For example: - Take a LVM snapshot in the initiator with "lvcreate". - Give read-only
