Hello, I'm looking for some assistance in modifying the rsync code Situation: I used to back-up some of my (unmounted NTFS) disk partitions remotely using the following shells construct: dd if=/dev/hda1 | gzip | ssh me@backupmachine 'cat > /backup-dir/hda1-backup.gz' But now I want to use rsync for this, since transfering 10 gig takes a litle to long if a file of a few kB has

Hi, I''m trying to clarify if it''s at all possible to live resize a disk image. After trying and failing it seems that the reason a disk image cannot be resized - is that domU is only able to detect changes in partitions (eg. partprobe), not in block devices as the xvd driver lacks a rescan feature. My domU sees disk images as blockdevices - that is without a partition table,

Hi, I am working as a system administrator at an internet platform service provider, and I am currently seeking to re-new our Xen virtualization infrastructure for which I am mostly responsible for. Currently, we run Xen 3.4.2/3.4.3 on RHEL/CentOS 5.x (5.7) as Dom0 with CentOS 5.x pv-guests. Based on my experiments, I am currently looking into Xen 4.1.2 on RHEL/CentOS 6.x (6.2), with a

Hi, currently i'm following https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit. I 'm playing around with it and it seems to be quite nice. What i want is a daily consistent backup of my image file of the guest. I have the idea of the following procedure: - Shutdown the guest (i can live with a downtime of a few minutes, it will happen in the night). And i think

Good day, Using 3.0.3-13.fc6, I ran into the following issue during a live migrate (on the receiving host): [2007-12-11 11:12:45 xend 5539] DEBUG (blkif:24) exception looking up device number for hda2: [Errno 2] No such file or directory: ''/dev/hda2'' Apparently, the host that guests are migrated to looks up the block device major/minor by searching for the device node

With the default settings in my Supermicro motherboard CentOS calls my SATA drive /dev/hda. If in bios setup I change 'Native Mode Operation' from auto to 'Serial ATA' it boots up calling the drive /dev/sda. I keep thinking its likely better under /dev/sda not? Any problem switching it to that after install? Matt

HI, i''m currently trying to connect a rails app using the "her" gem/library (since active ressource is gone since rails 4) to Puppet''s REST API. Now, "her" or activeressource both speak json, while Puppet speaks pson, which should be nearly the same according to some posts here. Communication already works but it seems that the response objects are not

Hi, just upgraded my testsystem to 3.0.4 (using the provided source rpm, xen-3.0.4.1-1.src.rpm, rebuilt it to run on non-PXE but no changes besides that, and it doesn''t look like the 3.0.4-testing HG has major differences so far?) and I have two problems with rebooting domains (xm reboot, or reboot from inside the domain). 1) the kernel-commandline keeps growing. On the first boot

Hello ext users, in a recurrent need to be able to traverse large filesystems (10-350M inodes) backed by spindle-based RAID arrays, I tried several solutions (like intercepting readdir and sorting by inode, playing with cache hints, and such), to no avail. Since I'm mostly facing ext3 and ext4 filesystems, I wrote a tool based on libe2fs which replaces the 'find /' part by

Hey all, I''m thinking about moving my 2.0.7 install over to 3.0.0 for eventual use in a production environment. Two questions: 1) Do people think 3.0.0 is ready for production - or is it just a testing/unstable playpen? 2) What do I have to change - just the xen-2.0.7.gz for do I have to recompile the dom0/domU kernels too? Cheers, Matthew Walster

Hello all fellow Mac OS X Railers. I''m just setting up a new MacBook from scratch. Everything has gone very easily, so I decide to attempt to install RMagick from scratch once again, something that I''ve wrestled with in the past, finally punting and going with a DarwinPorts ImageMagick install then direct gem install of RMagick. Well, I had no problems and have achieved
