Public bug reported:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
New
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.

The behaviour should be expected. Since qemu 2.10, image locking is
enabled which make multiple QEMU processes cannot write to the same
image, even if boot snapshot and backing file at the same time are
not allowed.
You could get image info with the option "-U" as below:
$qemu-img info -U $ImageName
The reason qcow2 is not allowed is because metadata has to be read
from the image file, and it is not safe if the image is being used
by the VM, because it may update metadata while we read it,
resulting in inconsistent or wrong output.

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
New
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.

Thanks for the explanation, I thought it might be related, but:
1. The command executed is:
qemu-img create -f qcow2 -o backing_file=/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2 /tmp/libguestfsWrA7Dh/overlay1.qcow2
And the error:
qemu-img: /tmp/libguestfsWrA7Dh/overlay1.qcow2: Failed to get shared "write" lock
It's not clear why it'd need a lock on a freshly created qcow2 file, or why it'd fail taking one.
The backing file is indeed shared - are we concerned it might be in use?!
2. How do I know if qemu-img support the '-u' option or not? Is there
some way to probe for it?

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
New
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2

And it's OK if I kill the VM of course.

1. The error prompt may be misleading. I guess your backing image should
be running. It should report that "failed to get the lock of backing
image". The operation will be allowed in the future.
2. Check the help doc of qemu-img, the you can get the support sub-command by force share option "-U".
$ ./qemu-img --help | grep -- "-U"

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
New
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.

The higher layers deal with inconsistent output. We want a way to
turn off locking when *we* know that it's safe, qemu doesn't have a
way to know that.
Interestingly the -U option is undocumented, but it seems like what we
want here.
Yaniv, how about this (only lightly tested):

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
New
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.

qemu-img: fails to get shared 'write' lock
Status in QEMU:
Fix Committed
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2

And it's OK if I kill the VM of course.

Sorry I noticed this bug is filed against qemu. The fix was done in
libguestfs, it's not a bug in qemu as far as I know.

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
Fix Committed
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.

Title:
qemu-img: fails to get shared 'write' lock
Status in QEMU:
Fix Released
Bug description:
Description of problem:
Somewhere in F27 (did not see it happening before), I'm getting while running libguestfs (via libvirt or direct), a qemu-img failure. Note: multiple qcow2 snapshots are on the same backing file, and a parallel libguestfs command is running on all. However, it seems to be failing to get a lock on the leaf, which is unique, non-shared.
The VM is up and running. I'm not sure why qemu-img is even trying to get a write lock on it. Even 'info' fails:
ykaul@ykaul ovirt-system-tests]$ qemu-img info /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
qemu-img: Could not open '/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2': Failed to get shared "write" lock
Is another process using the image?
[ykaul@ykaul ovirt-system-tests]$ lsof |grep qcow2
[ykaul@ykaul ovirt-system-tests]$ file /home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2
/home/ykaul/ovirt-system-tests/deployment-basic-suite-master/default/images/lago-basic-suite-master-host-1_root.qcow2: QEMU QCOW Image (v3), has backing file (path /var/lib/lago/store/phx_repo:el7.4-base:v1), 6442450944 bytes
And it's OK if I kill the VM of course.
