Sheepdog disk images
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Sheepdog is a distributed storage system for QEMU. It provides highly
|
||||
available block level storage volumes that can be attached to
|
||||
QEMU-based virtual machines.
|
||||
|
||||
You can create a Sheepdog disk image with the command:
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
qemu-img create sheepdog:///IMAGE SIZE
|
||||
|
||||
where *IMAGE* is the Sheepdog image name and *SIZE* is its
|
||||
size.
|
||||
|
||||
To import the existing *FILENAME* to Sheepdog, you can use a
|
||||
convert command.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
qemu-img convert FILENAME sheepdog:///IMAGE
|
||||
|
||||
You can boot from the Sheepdog disk image with the command:
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
|qemu_system| sheepdog:///IMAGE
|
||||
|
||||
You can also create a snapshot of the Sheepdog image like qcow2.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
qemu-img snapshot -c TAG sheepdog:///IMAGE
|
||||
|
||||
where *TAG* is a tag name of the newly created snapshot.
|
||||
|
||||
To boot from the Sheepdog snapshot, specify the tag name of the
|
||||
snapshot.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
|qemu_system| sheepdog:///IMAGE#TAG
|
||||
|
||||
You can create a cloned image from the existing snapshot.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
qemu-img create -b sheepdog:///BASE#TAG sheepdog:///IMAGE
|
||||
|
||||
where *BASE* is an image name of the source snapshot and *TAG*
|
||||
is its tag name.
|
||||
|
||||
You can use an unix socket instead of an inet socket:
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
|qemu_system| sheepdog+unix:///IMAGE?socket=PATH
|
||||
|
||||
If the Sheepdog daemon doesn't run on the local host, you need to
|
||||
specify one of the Sheepdog servers to connect to.
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
qemu-img create sheepdog://HOSTNAME:PORT/IMAGE SIZE
|
||||
|qemu_system| sheepdog://HOSTNAME:PORT/IMAGE
