[PATCH 0/3] Add disks to LVM pool backend
by Daniel Barboza 10 Feb '14

10 Feb '14

From: Daniel Henrique Barboza <danielhb(a)linux.vnet.ibm.com> This patch series implements the backend changes to allow disks/partitions to be added to an existing LVM (logical) pool. The process, as discussed previously in kimchi mailing list, is to use 'vgextend' and 'virsh pool-refresh' commands to add the disks and then refresh the pool. It is also worth noticing that the existing data from the disks/partitions being added to the pool will be erased/lost. To test the patch: $ curl -u root -H 'Content-type: application/json' -H 'Accept: application/json' -X PUT localhost:8000/storagepools/<pool_name> -d '{"disks": ["/path/to/disk1", "/path/to/disk2"] }' Tip: to test the patch over and over with the same pool and disks without the need to destroy/create the pool: $ vgreduce <pool_name> disk1 disk2 $ virsh pool-refresh <pool_name> The above commands will restore the logical pool to its previous state, before adding disks 'disk1' and 'disk2' Daniel Henrique Barboza (3): Add disks to LVM pool: control and model changes Add disks to LVM pool: API changes Add disks to LVM pool: mockmodel changes docs/API.md | 5 ++++- src/kimchi/control/storagepools.py | 2 +- src/kimchi/mockmodel.py | 12 ++++++------ src/kimchi/model/storagepools.py | 35 +++++++++++++++++++++++++++-------- 4 files changed, 38 insertions(+), 16 deletions(-) -- 1.8.3.1

[PATCH 0/5] Host's repositories management support
by Paulo Vital 10 Feb '14

10 Feb '14

WIP: This V1 supports only YUM. APT will come in V2 due to finish tests. This patch set provides support to host's repositories management operations. At this point, an agnostic class is providing support to backend and REST API operations. In addition, YUM (for RHEL, Fedora, SLES and OpenSuse) and APT (for Debian and Ubuntu) specific classes are provided to support the operation os each software update system. To test the backend execute the following commands: $ cd tests $ sudo ./run_tests.sh test_model.ModelTests.test_repository_create $ sudo ./run_tests.sh test_model.ModelTests.test_repository_update $ sudo ./run_tests.sh test_model.ModelTests.test_repository_disable_enable To test the REST API, execute the following commands (all them are agnostic of the host's distro): 1) Get list of all repositories enabled in the host: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/ -X GET 2) Create a new repository: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/ -X POST -d' { "repo_id": "fedora-fake", "baseurl": "http://www.fedora.org", "gpgkey": "file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-fake-19" } ' 3) Get information from a specific repository: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/fedora-fake 4) Update a specific repository: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/fedora-fake -X PUT -d' { "repo_id":"fedora-fake", "repo_name":"Fedora 19 FAKEs", "baseurl": "http://www.fedora.org/downloads" } ' 5) Disable a specific repository: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/fedora-fake/disable -X POST -d '' 6) Enable a specific repository: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/fedora-fake/enable -X POST -d '' 7) Delete a specific repository: $ curl -u <USER> -H 'Content-type: application/json' -H 'Accept: application/json' http://localhost:8000/host/repositories/fedora-fake -X DELETE Paulo Vital (5): Host's repositories management: Update API.md Host's repositories management: Update REST API Host's repositories management: Update backend.

Discussion: 312 - LVM VG is left when removing logical storage pool
by Ramon Medeiros 10 Feb '14

10 Feb '14

Well, you can also test using virsh. Libvirt is not removing the vg and the pv when you delete a logical storage pool. The question is: is it better to fix libvirt, submiting a patch for they, or just remove the vg and pv on kimchi? -- Ramon Nunes Medeiros Software Engineer - Linux Technology Center Brazil IBM Systems & Technology Group Phone : +55 19 2132 7878 ramonn(a)br.ibm.com

[PATCH] Fix controller base code: Update function is not using model_args
by Rodrigo Trujillo 10 Feb '14

10 Feb '14

The model_args variable is used to pass information to functions. Specially in functions of sub-collections and sub-resources, it is used to pass the main collections and resources names/classes. The wrapper update function from control base was not using model_args, then some resouces might miss this information.

[RFC V2] Host's repositories support
by Paulo Ricardo Paz Vital 06 Feb '14

06 Feb '14

Hello guys. Here is the v2 of this RFC. v2 -> v1: * Changed repo_id to be optional in collection POST. Back end will create one if user doesn't provide one; * Dropped repo_name from collection POST. This will be automatically inferred by the baseurl; * Dropped enabled from collection POST. Each repository added by user will be disabled by default. User needs enabled it after the creation; * Dropped gpgcheck from collection POST. This will be automatically inferred by the presence of a gpgkey; * Dropped repo_type from resource GET; * Changed enabled to be required in resource GET; v1: This is the RFC for the Host's repositories support (task "Register YUM, apt, zypper repos" of 1.2 sprint 3). The support will be provided by adding in the control/host.py a new collection (Repositories), responsible to manage all repositories of the system, and a new resource (Repository), responsible to operate with a specific repository. All this management/operations will be transparent to host's package management system, being provided by one of the new back end classes. The back end support provides 4 new classes: 1) Repositories (object): Class to represent and operate with repositories information in Kimchi's perspective. It's transparent to host's package management system, and can execute all operations necessary: add repository, get all repositories list, get information about one repository, update a repository, enable and disable a repository and remove a repository. This class will load in run time the necessary classes to work with the host's package management: YumRepo for YUM systems based, AptRepo for APT systems based and ZypperRepo for Zypper systems based; 2) YumRepo (object): Class to represent and operate with YUM repositories. Loaded only on those systems that supports YUM (e.g. Fedora and RHEL), it's responsible to connect, collect and provide information of YUM repositories in the system. Also it's responsible to create/delete the files in disk to maintain the repositories in system after disconnection. 3) AptRepo (object): Class to represent and operate with APT repositories. Loaded only on those systems that supports APT (e.g. Debian and Ubuntu), it's responsible to connect, collect and provide information of APT repositories in the system. Also it's responsible to create/delete the files in disk to maintain the repositories in system after disconnection. 4) ZypperRepo (object): Class to represent and operate with Zypper repositories. Loaded only on those systems that supports Zypper (e.g. OpenSuse), it's responsible to connect, collect and provide information of Zypper repositories in the system. Also it's responsible to create/delete the files in disk to maintain the repositories in system after disconnection. Bellow I present the REST API for the repositories support. ### Collection: Host Repositories **URI:** /host/repositories **Methods:** * **GET**: Retrieve a summarized list of all repositories available * **POST**: Add a new repository * repo_id *(optional)*: Unique repository name for each repository, one word. * baseurl: URL to the repodata directory when "is_mirror" is false. Otherwise, it can be URL to the mirror system for YUM. Can be an http://, ftp:// or file:// URL. * is_mirror *(optional)*: Set the given URI of baseurl as a mirror list, instead of use baseurl in repository configuration. * url_args *(optional)*: Arguments to be passed to baseurl, like the list of APT repositories provided by the same baseurl. * gpgkey *(optional)*: URL pointing to the ASCII-armored GPG key file for the repository. This option is used if yum needs a public key to verify a package and the required key hasn't been imported into the RPM database. ### Resource: Repository **URI:** /host/repositories/*:repo-id* **Methods:** * **GET**: Retrieve the full description of a Repository * repo_id: Unique repository name for each repository, one word. * repo_name: Human-readable string describing the repository. * baseurl: URL to the repodata directory when "is_mirror" is false. Otherwise, it can be URL to the mirror system for YUM. Can be an http://, ftp:// or file:// URL. * url_args *(optional)*: Arguments to be passed to baseurl, like the list of APT repositories provided by the same baseurl. * enabled: Indicates if repository should be included as a package source: * false: Do not include the repository. * true: Include the repository. * gpgcheck *(optional)*: Indicates if a GPG signature check on the packages gotten from repository should be performed: * false: Do not check GPG signature * true: Check GPG signature * gpgkey *(optional)*: URL pointing to the ASCII-armored GPG key file for the repository. This option is used if yum needs a public key to verify a package and the required key hasn't been imported into the RPM database. * **DELETE**: Remove the Repository * **POST**: *See Repository Actions* * **PUT**: update the parameters of existing Repository * repo_id *(otional)*: Unique repository name for each repository, one word. * repo_name *(otional)*: Human-readable string describing the repository. * baseurl *(optional)*: URL to the repodata directory when "is_mirror" is false. Otherwise, it can be URL to the mirror system for YUM. Can be an http://, ftp:// or file:// URL. * is_mirror *(optional)*: Set the given URI of baseurl as a mirror list, instead of use baseurl in repository configuration. * url_args *(optional)*: Arguments to be passed to baseurl, like the list of APT repositories provided by the same baseurl. * enabled *(optional)*: Indicates if repository should be included as a package source: * false: Do not include the repository. * true: Include the repository. * gpgcheck *(optional)*: Indicates if a GPG signature check on the packages gotten from repository should be performed: * false: Do not check GPG signature * true: Check GPG signature * gpgkey *(optional)*: URL pointing to the ASCII-armored GPG key file for the repository. This option is used if yum needs a public key to verify a package and the required key hasn't been imported into the RPM database. **Actions (POST):** * enable: Enable the Repository as package source * disable: Disable the Repository as package source

[PATCH] Fix debug report - NEED TESTS
by Rodrigo Trujillo 05 Feb '14

05 Feb '14

In Fedora 20, the sosreport tool saves the report file in /var/tmp, which crashes kimchi. The --tmp-dir options should be the right approach but it is crashing in Fedora 20 (RHEL works). While waiting sosreport fix, this patch feache the file path and name from sosreport output. This code works on Fedora 20. Need more tests in Ubuntu(s), RHEL and older Fedora.
