CLVM enhancements and fixes (#12617)
This PR enhances the existing CLVM implementation which was based on the deprecated CLVM technology which was based on corosync/pacemaker. With RHEL 7 having reached EOL, CLVM seems to be broken. CLVM supports RAW volumes on LVM , where as CLVM_NG support QCOW2 on LVM.

Further details: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Modernized+CLVM%3A+Enhancements+and+CLVM_NG+support

NOTE: On testing - it was identified that incremental snapshots for clvm-ng do not work as expected. As of now it's been removed from scope. So, CLVM and CLVM_NG would only support full snapshots.


* add support for proper cleanup of snapshots and prevent vol snapshot of running vm

* remove snap vol restriction for sunning vms

* refactor clvm code

* add support for live migration

* add support for migrating lvm lock

* clvm deletion called explicitly

* made necessary changes to allow migration of lock and deletion of detached volumes

* fix create vol from snap and attach

* add support to revert snapshot for clvm

* add support to revert snapshot for clvm

* make zero fill configurable

* make setting non-dynamic & fix test

* fix locking at vol/vm creation

* fix revert snapshot format type and handle revert snapshot functionality for clvm

* 1. Create clvmlockmanager and move common code \n
2. handle attaching volumes to stopped VMs \n
3. Handle lock transfer when VM is started on another host

* add license

* remove command/answer classes from sonar coverage check

* add support for new gen clvm with template (qcow2) backing

* Add support for clvm_ng - which allows qcow2 on block storage , linked clones, etc

* fix test and use physical size + 50% of virtual size for backing file, while virtual size + pe for disk

* migrate clvm volumes as full clone and allow migration from clvm to nfs

* fix clvm_ng to nfs migration, and handle overhead calc

* support live migration from clvm_ng to nfs and vice-versa

* add support to migrate to and from clvm to nfs

* fix creation of volume on destination host during migration to clvm/clvm-ng

* support live vm migration between clvm -> clvm-ng (vice-versa), nfs -> clvm (vice-versa) and nfs->clvm-ng (vice-versa)

* add unit tests for clvm/clvm_ng operations

* Add support for incremental volume snapshots for clvm_ng

* prevent snapshot backup for incremental clvm_ng snaps, fix build failure, add unit tests

* fix lockhost on creation of volumes from snap and fix bitmap issue when migrating a vol with incremental snap

* restrict pre and post migration commands to only kvm hosts where vm has CLVM/CLVM-NG volumes

* evist lock tracking - use lvs command to get lock host than DB

* add test for pre/post migration

* Create a CLVM storage adaptor

* update existing clvm get stats method

* fix precommit check failure

* Apply suggestions from code review

* Apply suggestions from code review

Co-authored-by: Suresh Kumar Anaparti <sureshkumar.anaparti@gmail.com>

* improve lock host retrieval logic and quicker retrival using db host as first check point and then fanning out

* add proper support for resizing of clvm_ng which calculated PE correctly for qcow2 metadata

* fallback to full snapshots for clvm-ng - incremental not supported in 4.23

* expunge volume detail of lock host on vm expunge

* if vmmigration with volume is done to the same clvm volume group, then dont do data transfer, just lock transfer and vm

* add clvm pools with deterministic uuid , so as to prevent adding the same pool twic

* added a small improvement to factor in a senario when lv is inactive on all hosts, could happen in storage outage issue

* address comment - extract common code for endpoint identification if clvm pool type

* Address comments - add early return guard to reduce indentation

* minor improvement - when migrating vm with volumes, if there's a failures, change the clvm vols to exclusive on source from shared, and on success, change dest vol to exclusive only for cross-pool migration

* cleanup unused code and tests for incremental snaps for clvmng and other cleanups

* allow storage browser to list lv in clvm, fix clvm shrink, overprovisioning factor isnt used for clvm pools - so set it to 1 and prevented display of provisioning type for clvm

* no need to have locktransfercommand to execute in sequence

* increase lv cmd timeouts to consider cluster load

CloudStack UI

A modern role-based progressive CloudStack UI based on Vue.js and Ant Design.

Screenshot

Getting Started

Install node: (Debian/Ubuntu)

curl -sL https://deb.nodesource.com/setup_24.x | sudo -E bash -
sudo apt-get install -y nodejs
# Or use distro provided: sudo apt-get install npm nodejs

Install node: (CentOS/Fedora/RHEL)

curl -sL https://rpm.nodesource.com/setup_24.x | sudo bash -
sudo yum install nodejs

Install node: (Mac OS)

brew install node@24

Optionally, you may also install system-wide dev tools:

sudo npm install -g @vue/cli npm-check-updates

Development

Clone the repository:

git clone https://github.com/apache/cloudstack.git
cd cloudstack/ui
npm install

Override the default CS_URL to a running CloudStack management server:

cp .env.local.example .env.local
Change the `CS_URL` in the `.env.local` file

To configure https, you may use .env.local.https.example.

To use the community Simulator QA server you can do this:

echo "CS_URL=https://qa.cloudstack.cloud" > .env.local

This may be required for newer npm versions:

export NODE_OPTIONS=--openssl-legacy-provider

Build and run:

npm run serve
# Or run: npm start

Upgrade dependencies to the latest versions:

ncu -u

Run Lint and Unit Tests:

npm run lint
npm run test:unit

Fix issues and vulnerabilities:

npm audit

A basic development guide and explanation of the basic components can be found here

Production

Fetch dependencies and build:

npm install
npm run build

This creates a static webpack application in dist/, which can then be served from any web server or CloudStack management server (jetty).

To use CloudStack management server (jetty), you may copy the built UI to the webapp directory on the management server host. For example:

npm install
npm run build
cd dist
mkdir -p /usr/share/cloudstack-management/webapp/
cp -vr . /usr/share/cloudstack-management/webapp/
# Access UI at {management-server}:8080/client in browser

If the webapp directory is changed, please change the webapp.dir in the /etc/cloudstack/management/server.properties and restart the management server host.

To use a separate webserver, note that the API server is accessed through the path /client, which needs be forwarded to an actual CloudStack instance.

For example, a simple way to serve UI with nginx can be implemented with the following nginx configuration (to be put into /etc/nginx/conf.d/default.conf or similar):

server {
    listen       80;
    server_name  localhost;
    location / {
        # /src/ui/dist contains the built UI webpack
        root   /src/ui/dist;
        index  index.html;
    }
    location /client/ {
        # http://127.0.0.1:800 should be replaced your CloudStack management
        # server's actual URI
        proxy_pass   http://127.0.0.1:8000;
    }
}

Docker

A production-ready Docker container can also be built with the provided Dockerfile and build script.

Make sure Docker is installed, then run:

bash docker.sh

Change the example configuration in nginx/default.conf according to your needs.

Run UI:

docker run -ti --rm -p 8080:80 -v $(pwd)/nginx:/etc/nginx/conf.d:ro cloudstack-ui:latest

Packaging

The following is tested to work on any Ubuntu 18.04/20.04 base installation or docker container:

# Install nodejs (lts)
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs debhelper rpm
# Install build tools
npm install -g @vue/cli webpack eslint
# Clone this repository and run package.sh
cd <cloned-repository>/packaging
bash -x package.sh

History

The modern UI, originally called Primate, was created by Rohit Yadav over several weekends during late 2018 and early 2019. During ApacheCon CCCUS19, on 9th September 2019, Primate was introduced and demoed as part of the talk Modern UI for CloudStack (video). Primate was accepted by the Apache CloudStack project on 21 Oct 2019. The original repo was merged with the main apache/cloudstack repo on 20 Jan 2021.
