Calling guestfs_is_lv on btrfs subvolume throws an error.

The guestfs_canonical_device_name API was rewriting /dev/mdX as /dev/sdX. This is wrong since (eg) /dev/sd0 is not a device name, so if you pass the canonicalized name back to the API it will fail. virt-v2v was one tool doing this. --- src/canonical-name.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/canonical-name.c b/src/canonical-name.c index ae7b468..d72768f 100644 ---

This patcheset fixes errors in virt-sysprep and virt-sparsify. Here we have a common functionality: is_btrfs_subvolume. Doesn't it make sense to turn it into guestfs API? Also I found an issue. In 'virt-sysprep fs-uuids', the uuids for ALL filesystems are regenerated as many times as many roots are in guest. Is it done intentionally? Maxim Perevedentsev (3): mllib: add checking

RHEL 4's mkinitrd will fail to recognise that root is on LVM when running on a recent kernel/udev due to changes in naming. This patch detects LVM root for RHEL 4, and uses a dirty hack to frig mkinitrd if required.

virt-sparsify shouldn't die if sparsifying a filesystem that contains read-only LVs. https://bugzilla.redhat.com/show_bug.cgi?id=1185561 I thought about trying to make the LV writable temporarily, but I suspect that if the sysadmin has made the LV read-only, then they probably did it for a reason, so we shouldn't touch it.

If we want to permit more than 255 drives to be added, then we will have to add the disks to the same virtio-scsi target using different unit (LUN) numbers. Unfortunately SCSI LUN enumeration in the Linux is not deterministic (eg. two disks with target=0, lun=[0,1] can be enumerated as /dev/sda or /dev/sdb randomly). Dealing with that will require some very complex device name translation on the

I have a virtual machine in a Xen LV, that I would like to backup from hostA to hostB because hostA is software broken. How do I copy and recreate that LV on hostB?

Hi. I want to make a snapshot from a logical volume and noticed that there must be enough free disk space in the volume group. Actually there is no free disk space left. How do i shrink online /var without losing any data or restore from backup? I do not have physical access to the server. Specs: Dell PE SC1430 with a 5/i RAID Controller one RAID 1 array from the Dell RAID controller 2

I know how to change the UUID of Physical Volumes and Volume Groups, but when I try to do the same for a Logical Volume, lvchange complains that "--uuid" is not an option. Here is how I've been changing the others (note that "--uuid" does not appear in the man pages for pvchange and vgchange for lvm2-2.02.26-3.el5): pvchange --uuid {pv dev} vgchange --uuid {vg name} Any
