provisioners: add reconfiguring of PID limit The container runtime CRI-O limits the number of PIDs to 1024 by default. When many PVCs are requested at the same time, it is possible for the provisioner to start too many threads (or go routines) and executing 'rbd' commands can start to fail. In case a go routine can not get started, the process panics. The PID limit can be changed by passing an argument to kubelet, but this will affect all pids running on a host. Changing the parameters to kubelet is also not a very elegant solution. Instead, the provisioner pod can change the configuration itself. The pod is running in privileged mode and can write to /sys/fs/cgroup where the limit is configured. With this change, the limit is configured to 'max', just as if there is no limit at all. The logs of the csi-rbdplugin in the provisioner pod will reflect the change it makes when starting the service: $ oc -n rook-ceph logs -c csi-rbdplugin csi-rbdplugin-provisioner-0 .. I0726 13:59:19.737678 1 cephcsi.go:127] Initial PID limit is set to 1024 I0726 13:59:19.737746 1 cephcsi.go:136] Reconfigured PID limit to -1 (max) .. It is possible to pass a different limit on the commandline of the cephcsi executable. The following flag has been added: --pidlimit=<int> the PID limit to configure through cgroups This accepts special values -1 (max) and 0 (default, do not reconfigure). Other integers will be the limit that gets configured in cgroups. Signed-off-by: Niels de Vos <ndevos@redhat.com>

Make CephFS plugin stateless reusing RADOS based journal scheme This is a part of the stateless set of commits for CephCSI. This commit removes the dependency on config maps to store cephFS provisioned volumes, and instead relies on RADOS based objects and keys, and required CSI VolumeID encoding to detect the provisioned volumes. Changes: - Provide backward compatibility to provisioned volumes by older plugin versions (1.0.0 or older) - Remove Create/Delete support for statically provisioned volumes (fixes #382) - Added namespace support to RADOS OMaps and used the same to store RADOS CSI objects and keys in the CephFS metadata pool - Added support to mention fsname for CephFS provisioning (fixes #359) - Changed field name in CSI Identifier to 'location', to denote a pool or fscid - Updated mounter cache to use new scheme - Required Helm manifests are updated - Required documentation and other manifests are updated - Made driver option 'metadatastorage' as optional, as fresh installs do not need to specify the same Testing done: - Create/Mount/Delete PVC - Create/Delete 5 PVCs - Mount version 1.0.0 PVC - Delete version 1.0.0 PV - Mount Statically defined PV/PVC/Pod - Mount Statically defined version 1.0.0 PV/PVC/Pod - Delete Statically defined version 1.0.0 PV/PVC/Pod - Node restart when mounted to test mountcache - Use InstanceID other than 'default' - RBD basic round of tests, as namespace is added to OMaps - csitest against ceph-fs plugin - NOTE: CephFS plugin still does not detect and address already created volumes but of a different size - Test not providing any value to the metadata storage parameter Signed-off-by: ShyamsundarR <srangana@redhat.com>
