Hi,
i try to create a LVM backed qcow image, but it seems qcow does not
like LVM.
=== create qcow image LV ===
# lvcreate --name xendom_qcow --size 100G xenvol
# mkreiserfs /dev/xenvol/xendom_qcow
# mount /dev/xenvol/xendom_qcow /var/lib/xen/images
=== create base LV and fill with data ===
# lvcreate --name xendom_base_qcow --size 10G xenvol
# mkreiserfs /dev/xenvol/xendom_base_qcow
# mount /dev/xenvol/xendom_base_qcow /mnt
# tar cpjf domu-base.tar.bz2 -C /mnt
=== create file backed qcow image ===
# qcow-create 5120 /var/lib/xen/images/xengate_root.qcow
# xm block-attach Domain-0
tap:qcow:/var/lib/xen/images/xengate_root.qcow xvda1 w 0
# mount /dev/xvda1 /mnt
[... mount is hanging forever ...]
# dmesg
[...]
ReiserFS: xvda1: checking transaction log (xvda1)
blk_tap: Can't get UE info
???

Next try,
using a logical partition ...
=== prepare image partition ===
# mkreiserfs /dev/hdc5
# mount /dev/hdc5 /var/lib/xen/images
=== prepare base partition ===
# mkreiserfs /dev/hdc6
# mount /dev/hdc6 /mnt
# tar cpjf domu-base.tar.bz2 -C /mnt
=== create file backed qcow image ===
# qcow-create 5120 /var/lib/xen/images/xengate_root.qcow
/dev/hdc6
# xm block-attach Domain-0
tap:qcow:/var/lib/xen/images/xengate_root.qcow xvda1 w 0
# mount /dev/xvda1 /mnt
[... changing some files ...]
# umount /mnt
[... umount is hanging forever ...]
# dmesg
[... nothing interesting ...]
Do i anything wrong here? Or maybe a broblem with reiserfs?
BTW, how stable is qcow considered at the moment? Reading the README
it seams quite mature to me.
