The main goal of these patch series is to implement a new API that allows to retrieve created device-mapper devices for volumes and partitions back after they have been created. As part of this patch: - required libdevmapper version was bumped to 1.02. I think it is safe because it was released more then 10 years ago; - newer version of libdevmapper allowed to simplify code base a little bit; - libdevmapper (and a good practice) suggest using UUID for device-mapper devices. It is get implemented as well. Presence of...

Original version linked from here: https://bugzilla.redhat.com/show_bug.cgi?id=1808977#c8 There is no change in the code in this series, but feedback from the original series was we shouldn't lose the error message in patch 7. When I tested this just now in fact we don't lose the error if debugging is enabled, but I have updated the commit message to note what the error message is in the

These commits, along with the associated changes to common: https://www.redhat.com/archives/libguestfs/2020-March/msg00286.html support the transparent decryption and inspection of Windows guests encrypted with BitLocker encryption. To do the BitLocker decryption requires cryptsetup 2.3.0 (although cryptsetup 2.3 is not required for existing LUKS use). It also requires a new-ish Linux kernel, I

As discussed in the emails today, this is the third version addressing most points from the v1/v2 review. You will need to pair this with the changes in libguestfs-common from this series: https://www.redhat.com/archives/libguestfs/2020-September/msg00050.html Rich.

Are there any plans for a type of "snapshot" support, which could be use to make point in time consistent backups, similar to what lvm would allow you to do for a local volume? I'm really looking for a good way to back up my ocfs2 volume, but so far, all we've been able to use is rsync and custom scripts. Are there any other options? -- Michael S. Moody Sr. Systems

Hi 2 all ! I have problems with concurrent filesystem actions on a ocfs2 filesystem which is mounted by 2 nodes. OS=RH5ES and OCFS2=1.2.6 F.e.: If I have a LV called testlv which is mounted on /mnt on both servers and I do a "dd if=/dev/zero of=/mnt/test.a bs=1024 count=1000000" on server 1 and do at the same time a du -hs /mnt/test.a it takes about 5 seconds for du -hs to execute: 270M
