When listing logical volumes, ignore the ones which don't get activated automatically. No /dev/VG/LV device node is created for these ones which confuses APIs that attempt to do 'guestfs_lvs' followed by opening the device node. Note that 'guestfs_lvs_full' is unaffected by this change. --- daemon/lvm.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git

lvm2 2.02.107 adds the -S/--select option used in lvs to filter out only public LVs (see RHBZ#1278878). To make this work again with versions of lvm2 older than that, only on old versions filter out thin layouts and compose the resulting device strings ourselves. The filtering done is much simplier than what "-S lv_role=public" will do, but should be good enough for our need. ---

Hi, this series improves the way LVM is used in the appliance: in particular, now lvmetad can eventually run at all, and with the correct configuration. Also improve the listing strategies.

The appliance has no LVM system ID set, which means that lvm commands will ignore VGs with a system ID set to anything. Since we want to work with them, pass --foreign at least when listing them to see them.

This hook script tries to address the fact that a RHEV-H installation will format all the storage devices available in the machine in order to create HostVG and AppVG with all the available space. It may be the case that RHEV-H needs to respect and co-exist with a proposed partitioning scheme, not getting all the storage space for HostVG and AppVG volume groups. The proposed solution adds the

Do you have some comparasion of IO performance on thin pool vs. qcow2 file on fs? In my case each VM would have its own thin volume. I just want to overcommit disk-space.

Hi! I need to convert a KVM virtual machine from LVM to a qcow2 image, and wonder if this is the best way to do it (*1): [$] qemu-img convert -O qcow2 /dev/vg_name/lv_name/ /var/lib/libvirt/images/image_name.qcow2 If this is the best way to do this, will this keep the information on: /dev/vg_name/lv_name/ untouched? Thanks, and please point me towards another mailing list if this it not right

It looks like older versions of lvm2 (recent enough to have selectors) do not recognize '1' (and '0') as boolean values. Switch to 'yes', which seems to be supported.

v2 was here: https://www.redhat.com/archives/libguestfs/2017-June/msg00008.html This series gets as far as a working (and faster) reimplementation of ‘guestfs_list_filesystems’. I also have another patch series on top of this one which reimplements the inspection APIs inside the daemon, but that needs a bit more work still, since inspection turns out to be a very large piece of code.

Hello, Novice programmer. I'm writing C source code and compiling it in as *.dll in the terminal by R CMD SHLIB foo.c. It works, I'm on a 64 bits windows system. I have the lastest R 2.15.0 and Rtools using the gcc 4.6.3 compiler. However, that was a hello world run, and I installed GSL for the 64 bit system for fast MCMC. The Rcpp package was easy to use, but I opted for a C with GSL
