search for: getsize64

When fetching a storage volume over SSH, we were detecting its size with a simple 'stat -c %s'. While this works fine for files, it won't return the correct size of a block device. This patch uses the output of 'blockdev --getsize64' for block devices, and stat as before for regular files.

Hi list. I''m running Xen 4.0.1 on Debian. I''m trying to live resize a block device : - I have a arbitrary block device in my dom0 (/dev/mapper/vm-vol42). - I start a PV domain with that device as a disk (disk = [''phy:/dev/mapper/vm-vol42,xvda,w'']). - I resize vm-vol42 in the dom0 (adding size only) - the dom0 sees the device''s new size. -

Hallo, linux-btrfs, First I create an array of 2 disks with mkfs.btrfs -d raid0 -m raid1 /dev/sdb1 /dev/sdd1 and mount it at /srv/MM. Then I fill it with about 1,6 TByte. And then I add /dev/sde1 via btrfs device add /dev/sde1 /srv/MM btrfs filesystem balance /srv/MM (it run about 20 hours) Then I work on it, copy some new files, delete some old files - all works well. Only df

Unless you're lucky, the target volumes won't be in a storage pool, so libvirt will return an error. For libvirtxml we know that the storage is local, so we can inspect it directly. We use qemu-img to determine format and file size. --- lib/Sys/VirtV2V/Connection/LibVirtXMLSource.pm | 48 ++++++++++++++++++++--- 1 files changed, 41 insertions(+), 7 deletions(-) diff --git

...e to keep my domUs untouched for the migration process so i tried to start a domU on my new xen host with the old configuration and old domU kernel. But it fails to access the disks and i don''t know what am i missing!? The disks are accessible from the new xen host with e.g. blockdev --getsize64 /dev/xbd/test1.sda2 Has anyone an idea for me what''s wrong? Is it possible that device names within the domU has changed? Additional info: ==================================== root@xenhost:~# cat /etc/xen/test1 name = "test1" #cpus = "" vcpus = "8" memory...

Hi Rich, This is v3 series to add support for resizing MBR logical partitions. changes to v3: 1. merge patch 1 and patch 3 in v3 2. let mbr_part_type return 'primary' for GPT partitions 3. add test for resizing logical partitions 4. fix extending the extended partition (yet). see patch 7. changes to v2: 1. remove p_part_num 2. remove filter_parts 3. name the function

This started as a simple warning-elimination change. I'll get back to that series shortly ;-) It turned into a factorization and constification exercise during which I got a taste of ocaml. Thanks to Rich Jones for help with a few snippets in generator.ml. The overall result is that many previously-manually-maintained bits from daemon/*.c functions are now hoisted into the automatically-
